  • December 7, 2018 at 6:48 pm

    Is there a ship date as of yet?

    • December 8, 2018 at 8:56 am

      The company is trying to raise additional funds to complete the manufacturing of the YARRA 3DX. As a result, there is no ship date. And there is a very real chance that the company fails to deliver the promised YARRA 3DX sound bars at all.

      • December 8, 2018 at 9:38 pm

        I hope you can understand my frustration, but why, if there is very little chance of our pledges bearing fruit with delivery of the Yarra 3DX, do you continue to demonstrate it and tell everyone it is so good? You’ve all but admitted that it won’t be getting made, why demo it; don’t you understand the sensitivities of those who pledged $’000’s and who will get no return?

        • December 9, 2018 at 7:44 am

          I went to London to demonstrate the unit to friends and people with distribution opportunities because these individuals were interested in partnering with me in getting YARRA 3DX manufactured and delivered. These same people will be very helpful in funding a new company targeting the same product line using the same technology. There will be a new 3D audio sound bar from myself or others — it’s just going to take longer than before.

  • December 7, 2018 at 7:13 pm

    Happy Holidays, Mark and Family!
    No reply necessary, but I am a bit surprized that a more accurate forecast of the launch cost of the Yarra wasn’t made. That seems to be the crux of the launching of a new enterprise. What about Shark Tank?

    The other idea I had, retro as it is, was to introduce the box as a DIY kit. That would no doubt exclude some buyers but possibly some of the adept might offer the assembly at a price lower than factory. Don’t know. The other problem is persuading someone (like me) who have $$$’s invested in conventional sized speakers, that it is possible for a phased box to actually work. But which would they ultimately choose — who would buy their old setup? Sounds like a free trial is necessary. Ship a trial system out for 10 days – if they want one, ship a new one. This is a huge key to Amazon’s success – you essentially run NO risk in buying from them.
    Good luck

    • December 8, 2018 at 8:59 am

      Robert, the funds raised through the campaign were sufficient to pay for the tooling, development, parts, and manufacturing of 2700 units. Unfortunately, the company spent the money on normal company operations and do not have the resources to complete the remaining tasks — including manufacturing and shipping.

  • December 7, 2018 at 7:32 pm

    Appreciate your efforts to help see this through to fruition.

    Merry Christmas

  • December 7, 2018 at 7:57 pm

    Hi Mark. I started to get excited when I saw this most recent post. Like you, I have (2) units coming. Tues. I am going to pop in on Comhear again and see if I can do some more listening. It has been a few months and I didn’t get to hear the new sub.
    I hope you are able to do something.
    Take care.

    • December 8, 2018 at 9:01 am

      Glen, my efforts to rescue the YARRA 3DX have proven unsuccessful. I hope we all get out sound bars but it’s difficult to imagine how additional investors will be excited by spending $1M to make the backer community whole.

  • December 8, 2018 at 2:21 am

    ‘ I was hoping it would be the YARRA 3DX but perhaps a new venture will have to take the lead.’
    Is that a hint on something coming, or just a sigh?

    • December 8, 2018 at 9:02 am

      I am already talking to the very same partners about producing a bigger and better sound bar akin to the YARRA 3DX. I’ll let everyone know when I’ve got specifics.

  • December 8, 2018 at 2:26 am

    Can you please describe, how exactly did you bring a DVD-Audio content (‘Love’) into Yarra. Thank you in advance.

    • December 8, 2018 at 9:03 am

      I used DVD Audio Extractor. It can rip audio files from DVDs or Blu-rays.

      • December 9, 2018 at 10:50 am

        And what file format did you input into Yarra after ripping the DVD Audio disc ‘Love’?

        • December 9, 2018 at 12:49 pm

          The YARRA 3DX can accept PCM, AC3, or APTX HD via TOSLink, HDMI, or USB. I took the wav files from the rip and created an interleaved AC3 (Dolby Digital) files and added it to the DVD iso image.

          • December 9, 2018 at 1:27 pm

            When you say PCM, do you mean multichannel PCM, or stereo PCM?

          • December 10, 2018 at 5:39 am

            The YARRA 3DX works with stereo PCM, multichannel Dolby Digital and multichannel APT X HD.

          • December 10, 2018 at 4:34 am

            And why to lossy Dolby Digital and not to lossless PCM, your and our favourite format?

          • December 10, 2018 at 5:39 am

            The system does a lot of processing and MCH PCM is not possible.

  • December 8, 2018 at 3:08 am

    I would love to hear one of these as if it works as advertised (and based on the above I have no reason to doubt that) then it’d be an ideal solution for people like me who’d like an immersive 3D sound but who can’t face the hassle of running speaker cables around a room and setting up AV receivers etc. Actually it is not so much me but my wife who’d object. I did look at using a 2.1 system with BT speakers for the rear channels but then you still need to get them positioned and mounted and near to power points unless you want to live with batteries which need constant recharging and risk dying in the middle of a movie or music listening session. Therefore the Yarra 3D sound bar would be just what I am looking for. I did try listening to one of the Yamaha sound projector sound bars and while it did sort of work it wasn’t that brilliant either. So I’m rooting for the company behind this to get their finances sorted out and start delivering product. I hope you enjoyed London!

    • December 8, 2018 at 9:05 am

      The trip to London was great. I was thrilled to be able to visit Abbey Road and visit with friends. There are a lot of people just like you that will benefit from a 3D audio sound bar. The Yamaha and other “bouncing” sound bars don’t do it for me either.

    • December 10, 2018 at 11:04 am

      John, which Yamaha beamforming bar did you try? I use a YSP-2700 and have been quite satisfied with that once I ran the room correction and then tweaked the settings manually using the MusicCast app. Until this Yarra product somehow hits the market in some iteration Yamaha products may be the only option. I will also admit that these sound bars, while somewhat functional, sure do not hold a candle to a fully immersive 5.1 system like Mark demonstrated at Axpona. Unfortunately my new home did not have room for separates.

  • December 8, 2018 at 3:27 am

    Ah Mark, I can’t believe you were just up the road from me in Guildford! It’s an interesting town with its famous university (University Of Surrey), with its strong links to space and satellite development (SSTL) at the research park. Nearby is also the home of the Mullard Space Science Laboratory, The Academy of Contemporary Music, and Hurtwood House. Of course the locale is also home to musicians such as Bill Bruford, Paul Wellar, Kenny Jones, and Eric Clapton. And there’s lots of history here too. I hope you had an enjoyable visit, and with a bit of luck you’ll be back to Guildford again soon, perhaps you can stay a little longer.

    • December 8, 2018 at 9:08 am

      Thanks Sean. I really didn’t know much about where I was…my friend Richard has the connection to the area. I’m sure I will be back in the near future. My youngest son was just awarded a fellowship to the Richard Rogers Wimbledon House for the fall of 2019.

  • December 8, 2018 at 10:47 am

    I put money down based on your recommendation of product and company. I won’t be doing it again.

    • December 8, 2018 at 10:51 am

      Trevor, I understand and regret the situation that occurred with the YARRA 3DX. When I started consulting for the company, the CEO and team were competent, honest, talented, and forthright. In the intervening many months, most of the original people have left including the former CEO and my close friend the CSO. The product was — and is — a genuinely innovative piece of engineering and does what it’s supposed to do. The operation of the company under new management has resulted in all of us — including me — losing our pledges. I’m sorry I wasn’t able to rescue the product. I tried.

  • December 8, 2018 at 6:25 pm

    Thank you, Mark! I hope you Mona have a wonderful Christmas & New Year! Also, thanks for all you’ve done in trying to fix this mess. From all of the reviews I’ve been reading, usually in your posts, we’re really going to miss out on a great sounding product.


    • December 9, 2018 at 7:40 am

      A sound bar that incorporates beamforming and wave field synthesis will make is way to the marketplace in the near future. It is indeed unfortunate that YARRA 3DX will likely not be that product. But I’m pushing hard to bring the same development team together to build the Beamsonic 2.0. Stay tuned.

      • December 11, 2018 at 1:19 am

        ‘But I’m pushing hard to bring the same development team together to build the Beamsonic 2.0. Stay tuned.’
        Please be sure that it has enough processing power to handle multichannel PCM.

  • December 8, 2018 at 11:41 pm


    Thanks for the update. I understand the frustration you are feeling and just hope I can own one of these soundbars in my lifetime. Even if it means having to buy one from another company that will actually be able to build them.

    • December 9, 2018 at 7:46 am

      Thanks Kit. It’ve very disappointing to see the way the company squandered a rare opportunity. The lack of vision, incompetence, and inability to see the obvious makes it even worse. There are plans to move into the same market with a bigger and better 3D audio sound bar — run by people that have integrity and a solid plan.

  • December 10, 2018 at 6:06 am

    Mark, WE WERE THE BACKERS. We funded a this project well over a year ago based on seeing a product that was fully designed and manufactured in enough units to demo its capabilities at trade shows & backer events. Based on all the conversations and updates there were evidently enough units made to distribute to a select group. Based on all that was presented who would not have thought that the project was not ready to launch? All the talk & PR about working out the details and tweaking the design now appears to have been a delay tactic for the company to make there exit. Above you say “The company is trying to raise additional funds to complete the manufacturing of the YARRA 3DX.” Who would partner with a company that has mismanaged over $800K and failed to produce the product for the initial backers? I’m sure there were a lot of us who were influenced by your recommendations and need to reconsider things moving on. Very disappointing Mark. As they say, Fool me once….

    • December 10, 2018 at 6:57 am

      Mike, everything I had stated was true. Company management spent the money that was supposed to mass produce the product on company operations. It is ready to manufacture and I spent lots of my own money, time, and resources finding partners to take it over and get you your bar. The CEO declined my offer. You’re right that I doubt anyone will invest additional funds in a company that has spent millions of dollars without anything to show for it. I can definitively state that there was no fraud involved. YARRA 3DX exists (there are about 10 EVTS units) and is ready to manufacture when the bills are paid. It is very disappointing for me as well. I did everything I could and more to get the backers the units they deserve.

  • December 10, 2018 at 9:19 am

    Hi Mark, How can a CEO decline an offer when they have no intention of delivering a product that they accepted alot of funds for? Sounds like fraud to me! THe feeling of getting Burned will likely exclude me from any future purchase.

    • December 10, 2018 at 1:59 pm

      He told me that he wants to reserve the right to offer the underlying technologies to other potential consumer electronics companies. If AIX and partners couldn’t be given so sort of exclusive protection against a directly competing product in the consumer marketplace, we couldn’t proceed. It was proving very difficult to raise the funds to make backers whole, but I had the pieces in place. Comhear and its management have demonstrated a lack of empathy and understanding of the entire situation.

  • December 10, 2018 at 10:55 am

    So based on Comhear company press it seems that they raised funds via Kickstarter, and then migrated those funds to another crowdfunding site called Indiegogo, where they raised even more money. Then they proudly announced the relocation of their corporate headquarters to some new site, probably using all the crowdfunding money. Someone needs to sue and put a lien on that property if possible based on the terms of the crowdfunding sites. I am sure some of the backers are attorneys and would be more than happy to step up on this. Being a happy owner of a Yamaha sound bar with beamforming technology I did not succumb to this initial offer, but have to say I was very tempted a time or two. I’m glad now I did not even if my current technology does not match up with the Yarra bar.

    • December 10, 2018 at 2:01 pm

      Larry, it is indeed unfortunate that the company was severely mismanaged after we successfully raised enough money to develop, manufacture, and deliver all 2700 units to KS and IGG backers. It seems there is sufficient anger and motivation to cause the company’s reputation and bank account to diminish.

  • December 11, 2018 at 4:39 am

    Hi Mark
    Thank you for being so forthright and honest with the backers on ks.
    Although this leaves a bitter taste, as I have stated on the ks comments page as well, I fully trust your efforts to bring this to market (you were the only reason I put down money the first time) and if you do end up starting a campaign please let the community here know I’m sure there will be plenty of backers including myself

  • December 11, 2018 at 7:13 am

    I’m so glad that I did not recommend this to family and friends, and that I commited to one unit only. It still stings but could have been much worse! I would be surprised if this company has a future

  • December 12, 2018 at 10:24 am

    I received no cooperation on my visit to La Jolla. It is a shame no product is forthcoming. I had the luxury of spending 2 solid hours listening to the Yarra 3DX at the new headquarters, several months ago. Both the Near Field and Far Field sessions were very impressive, which had me investing in (2) units. The original developers were great people. I hope Mark is able to come up with something.

    • December 14, 2018 at 10:01 am

      It’s s drag that the company has not lived up to its promises. I haven’t completely given up yet.

  • December 12, 2018 at 11:16 pm

    Thanks to this Yarra fiasco, I will NEVER fund any e-begging future projects.

  • December 16, 2018 at 3:09 pm

    I also put down money for a soundbar which it seems I have lost due to operational decisions taken by the company’s management. We backers have in effect provided the company with free working capital which it is now unable to repay. It therefore sounds to me as if the company is knowingly trading while insolvent, which in some jurisdictions is a criminal offence. It should be wound up without delay before other people get burnt.

  • December 18, 2018 at 9:01 am

    I think the communication and comments here, created by Mark, have them communicating with the backers again. All we can do is wait and see. I’m hoping they might pass information on to Mark when it becomes available.

    • December 26, 2018 at 7:20 am

      We’ll see where this goes. I’ve made an offer to work with the company and new Chairman to get the sound bars delivered. I’ll keep you posted.

  • February 18, 2019 at 8:36 pm

    Any updates since you last post?

    Thank you,

    • February 19, 2019 at 11:19 am

      I’ll get another post up soon.

    • February 20, 2019 at 1:43 pm

      Michael, Comhear has a variety of products for commercial installations. The MyBeam ProAV was one of their first products. I’m not aware of any major customers but there may be some. I never heard the one advertised but they are fundamentally different than the YARRA 3DX.

      • February 20, 2019 at 2:07 pm

        Thanks for quick response Mark. It may be fundamentally different, but the specs on it are certainly promoting it for the same market segment as the YARRA 3DX. This is not being marketed for commercial installations.
        “Get a reliable, crystal clear 360° immersive sound experience in an elegant, compact speaker shell that perfectly complements PC set-ups, gaming consoles, home entertainment systems and small spaces.”

        It’s just a bit confusing given where we’re at with the YARRA situation. BTW, will you be calling in to the conference call on Monday?

        • February 20, 2019 at 2:11 pm

          The MyBeam speakers don’t have Dolby Decoding or Binauralization software in them. Yes, I will try to do the call but I’m teaching a class starting at 8:30. I hope someone records it.

  • July 3, 2019 at 5:13 am

    Today it arrived!

    Mark, today I really got one of the two Yarra 3DX!!

    Thanks a lot for all the effort that you and of course Peter put into this. And I think you are a pleased as I am, that the backers now got what they paid for in the first place.

    You did an excellent job tuning the speakers. The sound is full, rich and spacial. I am just listening to various Pink Floyd recordings, these are perfect showcases for the Yarry 3DX, I am impressed.
    And I absolutely love the subwoofer. Such a tiny box, but what a bass! Without it the Yarra is just a squeaking box. Agaian perfectly tuned.

    This first Yarra is for my desk. And at the moment I am really happy with just listening to music in the “surround” mode. Pink Floyd, “Time” the clocks, at the start unbelievable! All around me.

    I also listened to your Blueray, great recordings, very good selection.
    The chamber music came as surprise to me, as all the other mixes are very wide and open, this one just sits in the middle. “Tiny” is what comes to my mind. But a good fit, it’s chamber music, isn’t it?.

    So a big thank you again!!

    • July 3, 2019 at 10:53 am

      Stefan, congrats on your new acquisition!! I haven’t heard a peep regarding my two units. I’ll keep waiting.

  • July 3, 2019 at 11:36 pm

    Hi Mark,
    Can you confirm that the Yarra 3DX will work with bitstream (Dolby) via Toslink? I’m using an Xbox One X as a source and it has only 2 options for the optical out (uncompressed stereo or bitstream (Dolby or DTS). Is bitstream (Dolby) the same as “AC3”?


    • July 11, 2019 at 10:27 am

      Yes, the original design planned for Dolby Digital (there is an internal decoder) and then binauralization prior to the beam forming speaker output. TOSlink is the connection.

  • July 11, 2019 at 12:25 pm

    Thanks for the feedback Mark. I was confused by the Yarra quick start guide which states for optical: Make sure the audio settings in the output device are set to PCM format.

    • July 16, 2019 at 6:08 pm

      I just started testing the Yarra. Generally good but a few questions. So far I’m not noticing any sense of sound coming from behind me. I’ve checked that with the speaker channel verification on your older AIX sampler disc, as well as with the Xbox One X outputting DD 5.1 via TosLink. Any suggestions on how to clearly demo sound from behind one’s head? Yarra settings? Yarra positioning? What about height of the Yarra relative to one’s head?

      I believe others are also having difficulty achieving the sensation of rear channel sound. Any advice much appreciated. Excited to finally have a unit.

      • July 21, 2019 at 7:40 am

        Michael, the system emulates the sound of a 5.1 surround system and its unlikely that you will experience sound directly behind your head. In some occasions (a moving sound for example) will seems to travel behind you, but in general think of a 5.1 setup with sound coming from the 110-120 degree position of a properly set up home theater.

        • July 21, 2019 at 2:27 pm

          Hello Dr. Waldrep,

          Thank you for your work and assistance to the Yarra backer community.
          I would appreciate if you would confirm whether the Yarra should be set to ‘Stereo’ mode or ‘Surround’ mode when handling already binauralised content? (for example, as you did with your Yarra & Smyth A8 demo combo?)

          I would have thought double processing the content should be avoided and thus the Yarra be set to stereo? However, I have tried feeding it pre-binauralised content in the form of ‘Dolby Atmos for Headphone’ (from PC and Xbox One) and if the Yarra is set to output in ‘stereo’ mode, the surround effect is somewhat unimpressive; not much better than what I get pumping that same Atmos for Headphoned content into my old stereo speakers.
          Setting the Yarra to ‘surround’, however, really does make everything seem more 3 dimensional, even though this is applying Yarra’s binauralising on top of the already pre-binauralised Dolby Atmos for Headphone source content. . .?

          Many thanks

          • July 30, 2019 at 12:34 pm

            I hope to get my own YARRA 3DX units shortly. I’m not sure what they’ve done with the software at this point. I’ll see if I can find out.

  • July 28, 2019 at 12:51 am

    Dear Dr Waldrep,

    Based on your conclusion for this post
    “…..I believe the answer is a full featured sound bar. I’m dedicated to making one available as soon as possible. I was hoping it would be the YARRA 3DX but perhaps a new venture will have to take the lead.”

    Could you please be a bit more specific on this idea? How would the new beamforming sound bar be as compared to the existing Yarra 3DX? For example, more than 12 drivers inside and also larger ones? The electronics to be more complex: decoders for Dolby Atmos, DTS:X and Auro-3D?

    I think other Yarra 3DX owners and I are interested to reading your thoughts, if possible.

    Thank you for your time.


    • July 30, 2019 at 12:38 pm

      George, the YARRA 3DX was designed to be affordable and demonstrate the power of beam forming audio. The drivers, amplifiers, and other components are not the highest available. The realization that the proper signal reaching our left and right ears is everything that we use to evaluate sound including fidelity, directionality, and balance makes me believe that a well done sound bar could replace MCH setups, headphones, etc. I’ll see if I can elaborate in a new post.

  • August 1, 2019 at 8:54 am

    Re Stereo vs surround mode for pre-binauralised content:

    Thank you Dr. Waldrep for your response, I eagerly await your findings.

    I have tried feeding the Yarra a variety of content, some of it ‘true’ binaural such as the famous “virtual barbershop” demo and some of it ‘converted’ binaural, i.e. originally discrete multichannel surround content that had been run through a binauralisation algorithm such as Dolby Atmos for Headphone, DTS Virtual X, Creative SBX surround etc.

    In all cases the placement of the directional cues required the Yarra to be set to surround mode in order to be remotely correct.

    e.g. In the virtual barbershop demo, if the Yarra was set to stereo mode, rather than *my* hair being cut, it would sound like *somebody else’s* hair was being cut a foot or two in front of me.
    Setting the Yarra to surround mode would rectify cue placement, but as with all other binaural or binauralised content fed to the Yarra, doing so had a highly detrimental effect on the quality / fidelity of the audio.

    To summarise, in my experience thus far, the only way to get good surround *and* good audio quality at the same time from the Yarra is when it is natively decoding Dolby Digital 5.1 content.

    Many thanks
