There are very good reasons to use two or more transducers.Dynamic transducers are cheap and lightweight. Unfortunately when you use one driver, then it needs displacement to play bass and phase accuracy to play highs. The former requires big size, the latter small size, or you'll get destructive modes all over FR.

So far we arrived at a consensus that 40mm driver is the golden compromise, however the bass will roll off and it doesn't look good in the marketing material. That's why 50mm driver are being marketed towards the "casual consumers". They have more displacement, but are bad at everything else and really only work with waveguides.

So you want to split the signal. The problem is that you need to find the actual drivers. Not only that, once you find the drivers of the right size, they need to make some quality noise. This is difficult, but it doesn't end there. The high quality drivers need to be mass manufactured or else the headphone will cost a fortune. So you end up using whatever basket of sketchy parts you can collect. In this case it seems like they found some Chinese earbud speakers, which probably were too small to cross them to the big boys, so they had to use two of them. Two drivers have more output and if they're small enough, they play like one driver. I probably sound very critical here, but this is actually how you design good audio.

The big boys still play quite high IMO, but what do I know. Optimally you want the bass to be completely separated from the rest but, as above, it's not always viable.

With drivers as small as theirs, they probably realised that they can reorient them so they're playing with the idea of HRTFing the driver's response. The important part is that they are as close to your ear canal as possible.

When you use multiple drivers of the same kind, the costs go down. Sometimes that's the difference maker. There's this company that makes loudspeakers out of tweeters. They can undercut other manufacturers and that's why they're popular.

In the past a headphone like this was not a viable option. Today we're getting to the point, when energy efficient and highly integrated chips can handle devices like these. The goal right is to find that secret sauce.

What is lossless? Is it audio without any kind of compression? If so, where can I get some?

Look within occupational safety/recreational shooting instead of audio. 3M, MSA, and Walkers all offer electronic hearing protection that filters out loud noises but amplifies anything below 85dB. If the battery dies they just turn into earmuffs. Get gel pads if you can afford the extra $50.

This hobby needs experience. Amplifier is amplifier. Though, you need to know things behind it. Class D, Class AB, Class A. These has different tech behind it and also power consumption. The quality of the power supply as well. These are the things that make the amplifier sounds differently.

umm…

So in the above picture, you will see three new designs that I’ve been working on with what I consider one of the best dynamic headphone drivers available no matter the cost. (They are all custom tuned- and if people wanted they could say how they want their set customized JUST for them)

anyway..

back to the story of how I came to this place…

They all measure extremely low in distortion and have a very revealing sound that digs deep into the recording on all spectrums of the frequencies . I’ve been testing them with DATSv3 I’ve been testing them with my CypherLabs Prautes Tube amp using Telefunken G73r tubes and with my solid state Ray Samuels Apache amp along with my FIIO Q5s and of course my Apple phone with the dongle (I had to test the dongle of course- and surprisingly it sounds really good with the Apple iPhone) - the headphones are very easy to drive since they’re rated 32 ohms with a minimum of 114 dB rated, but they do scale up to reveal the differences in amps and DACs… I could’ve chosen a 300 ohm or 250 ohm driver but my goal was to make a headphone that sounds fantastic with all devices that most people have around the house or may buy later on- my goal was to make them as beautiful sounding as my Vandersteen speakers- and anyone who knows they scale up beautifuly but always sound composed- and although they can play super loud - like the Vandesteens the do low volume detail EXTREMELY well- a rarity in headphones I think- where usually most typical headphones need huge amounts of volume to sound alive - with these it isn't necessary to have high volume to reveal all the details but when you want a club like experience in your head they can do it with distortion - kind of like a gentle giant or a performance car with loads of HP on tap when you need it... you wont have to buy expensive gear to make them sound good… but they will pay off when you do in the future.

SOooooo a little more background - it’s been nearly two years and all this testing and perfecting all sorts of dynamic drivers and tuning them as best I can - I had to find beautiful cups with very comfortable headbands that were reliable and would work on just about anyone's size noggen - so I’ve combined them as you can see in the pictures- with very nice real genuine hard wood designs that don’t look dorky but actually look kinda beautiful if I do say so - like the ones you see here in this picture - one is cherry one is walnut and one is dark walnut and all of them are very light under 45 ounces for the whole headband and set up …anyway the fractal mesh that I’ve been using on all of my headphone mods is also included in this new design, and I think no matter how much more research and development I do I don’t think I could perfect this any better I truly am loving the way the sound, and anyone who’s listen to them at my place feel the same way- spending hours going back-and-forth between probably 25+ headphones that I have here - and I don’t think anybody could find something better no matter the cost so I’m trying to keep these extremely low priced and high-quality and of course have sound quality that competes with some of the best in the market place - no matter if they are competing with $700-$2900 ranges - I feel completely confident that these will end anyone’s pursuit and finding the ultimate dynamic Headphone for crystal clear, highs, beautiful, smooth midrange and extremely deep bass that digs deep in to the recordings.

So far, I’ve only had three people actually take ownership of them, and every single one of them are hooked and text me daily on how much they appreciate the sound on these, and keep telling me I should raise my price, but I’m looking just for other opinions and for people to try them … I welcome anybody’s opinion or feedback I’m always looking to make things better and better…and I don’t think I’m using hyperbole here by saying all of this - I’m trying to be sincere and honest I really don’t think anybody will be disappointed - please pm me if you have questions

They're playing with interesting ideas. The video doesn't make the whole argument for that type of headphone and you see on the graph that they didn't fix all the problems in their FR at least in this prototype. Standing waves still make it difficult to reproduce high frequencies accurately.

One idea that I like is that they're splitting the signal into two bands which will help reduce intermodlation. That means that even when the drivers play bass loudly, frequency response in the upper range is not being altered by it.

I'm personally not interested in getting high frequency transducers to the front. I prefer to have them as close to your ear as possible.

I also like that they are not too big, which helps with low frequency extension. I'm afraid they might be heavy.

We will see how it evolves. The first iteration likely will have issues, but two models down the line they might squeeze some performance out of it.

So I’ve been working on finding the best dynamic drivers available spending thousands on R&D and combining them with a beautiful comfortable headset made from real wood - I am using my patent fractal mesh and well I think these will be very hard to beat…. Continued below…

Only times it happenned to me was a few weeks ago, after trying to use the Koss Porta Pro for my walk home(1h20 more or less) that I usually do with IEMs. Because there's a river that runs alongside the path and has quite a fast flow depending on the time of the year and weather, it can get very noisy to the point you have to almost scream to have a conversation with someone else, and thus without even noticing I pushed the volume too much to cover the noise of the river ...

​

The high pitched noise in my ears took about 48 hours to finally completely disapear ... Lesson learned, only gear that isolate well for the walk home from now on ...

Are you guys seriously using spotify ? I switched to Tidal and it's a lot better if you have good headphones.

Exactly this

Give yourself to the Dark Side, Luke

How can one thing vibrate 2000 times and second and 80 times a second at the same time ? Answer is it does not.

Try superpositioning two waves of 80hz and 2000hz and then you get a pattern of vibration which doesn’t look like 80 and 2000 but it’s a pattern which is the resultant of 80 and 2000. At some parts it’s added I amplitude (at time periods both parts are in the positive cycle and is present in the same time slice. Read superposition to undertand exactly the way in which how this pattern is formed.

Then this pattern of vibration reaches your ear where again different haircells deflect differently as they have different thresholds to produce an auditory signal.

Same. I downloaded my entire collection on FLAC (and I don't use it), most of them are on CD that i use something but i everyday Spotify. Classic.

I one time order a CD from japan just so I could hear the rest of an album I found on youtube lmao. The album doesnt exist anywhere else except as physical CD's.

Our hearing is objectively mono individually; one dimension. Our ability to tell direction is an evolutionary trait categorizing the frequencies and time the sound is heard between ears. Our ears are incapable of discerning direction without our brain telling itself what specific sounds in a specific order mean. Our brain is easily tricked by simply recreating those specific frequencies or adjusting when/if each ear hears a sound.

There isn't a substantial enough difference between people's ability to discern direction to need a significant personalized change to achieve a given 3d effect. Everyone's hearing is rarely accurate to direction, especially up and down anyway.

All that aside, a smart headset is a really interesting way for someone to label audio processing. Adaptable audio already exists and is not practical for headphones, as for actual physically 3d sound I'm pretty sure that exists and they are called "Speakers" specifically surround sound setups. As for headphones, binaural audio mixing is vastly more practical and is highly effective. Even to the point people, mostly audiophiles, make up nonsense terms and other weird things to headphones capabilities.

If your Audio Mastering is shit and you didn't do it right it doesn't matter how special your headphones are it won't sound good. But if you do it right then you can get a convincing 3D effect out of shitty decade old $5 ear buds you found in the back of your closet.

I don't quite understand the push back against the multiple drivers. Here are my observations:

• I have never heard a sound reproduction system that can be even closer to the original sound of the orchestra. During reproduction, the timbre of the instruments, the fidelity of the multiple instruments producing the sounds together are lost. As the source of sounds gets more complex, the worst the divergence gets.

• A single driver cannot produce all frequencies at the same magnitude. That's why we have subwoofers. Low frequency sounds from a smaller driver cannot have the same magnitude as the larger driver. Just like a large drum sound louder than small drum for the same frequency.

• A driver cannot immediately changes its movement due to inertia. Now there are techniques like planar drivers, electrostatic drivers to reduce the challenge but each solution comes with its compromise. This is also why we have equalizers to compensate on the physical limitations of the driver.

Now going from a single to multiple drivers introduce more noise as we add more processesing. Yet it also adds more flexibility to reproduce sound by using specialized driver for given target frequency.

We also need to understand the source of the sound. For orchestral sound like classic music, jazz music, the challenge is higher as the goal to reproduce original sound. For pop and rock music, sound is already engineered as there is no original sound but multiple soundtracks that are mixed by an engineer for optimal listening pleasure for target configuration. For the latter, two drivers are sufficient if the sound engineer targeted headphone based listening.

In a world with perfect microphone and perfect driver, yes we only need two drivers but they are not. The music is also not always mixed, prepared for two drivers.

>New song appears on Youtube and nowhere else
>You listen to it in inexpensive gear and love it
>It then comes out in FLAC
>Get your fancy gear and appreciate all the extra details you missed

That's a big win in my books buddy. Not every single session has to be critical listening

the difference is def minimal but when i've spent 4500 on my current chain chasing diminishing returns i might as well get the free return.

You almost understood it but I think if you look deeply superposition once again you would understand how this meme is meaningful and deeply true. I had a hard time in understanding this for long, and one day I got in!!

*bit depth of 1, bitrate of 1 would be 1 bit per channel per second, which wouldn’t sound too good

I'm in the middle

If I can get the highest quality possible, I will. Same with video files, always choose the best bitrate, even if it means 100gigs per movie xD
