    If this works out and is good, I'll most likely get a pair too. Definitely appreciate the transparency from the manufacturer. My only concern at this point is the detachable cable. I'm not sure if high voltage bias lines, detachable cables, and aftermarket cable manufacturers that have no clue what they're doing are a good mix. Otherwise looks very promising.
  2. DIY Audio Heaven tested a M&J headphone with this design including frequency response for each driver. https://diyaudioheaven.wordpress.com/headphones/measurements/mitchell-johnson-jp1-dj/ There appears to be no crossover. The dynamic driver contributes most of the sound while the electret pretty much plays in the background. The FR is a mess. At least the cheapo version I can understand, but for hundreds of dollars? Thanks for the teardown.

    Thanks for the offer, but no, I don't have them anymore. I had like 3 or 4 pairs at one point.

    No. They needed a good fit or they would sound off, too dull with a big dip in the upper mids. With the headband, I couldn't get them positioned right, and without the headband, they wouldn't stay in my ears unless the tips were physically big enough to be wedged inside the ear firmly enough to stay put. Then they would cause pain after 15 minutes and my ears would literally swell shut for days. So I couldn't use them. Yeah, they sounded great. What Kevin said is spot on. I preferred them over most things, especially for vocals. I don't know if the new one has a different driver, and I haven't tried the new tips. Sadly, as I get older, ergonomics only become more important.

    Where do you see L300 measurements in that thread? I only see L300LE. The only comparative measurements for the L300 I've seen are Tyll's and the ones here. As to whether or not they're more or less linear than previous Lambdas, see for yourself. My L700 audibly rolls off in the bass but as spritzer said, not that much. There is still audible extension down to 20hz, but sub-bass is quieter than it should be. Not a big deal IMO. Also I wear glasses that break the seal. The SR-003 I had and really liked how it sounded but the fit was awful to the point of actually causing pain after about 10 minutes, so I gave up on using them. That was with the old tips and the old drivers. Looking at the new tips, I'm still skeptical. Lastly, using aftermarket pads, especially non-Lambda ones, on Lambdas is something I'd be careful with. The driver/ear distance in an electrostat is important and changing it will change the sound.

    Well from what I remember Koss hasn't changed the original ESP950 since it was introduced, which was in the early 90s. A few years ago they were hit with a massive embezzlement crisis where a high ranking employee stole millions from the company. They're not exactly the world's biggest headphone manufacturer either, and I'm guessing that must have hurt. Considering that the 950 is a low volume marginal product, and everything else that has happened to them, spending R&D time fixing the original's issues or developing a thoroughly optimized new version is probably not high on the priorities list. Still, if you want one, I second Purk's suggestion to get the original, and I've seen them retail as low as $400, though that was some years ago too. The price will fluctuate and if you're not in a rush to get one now, there will certainly be a good deal to be had. That is, if you don't want to buy an L300 instead.

    Cloth earpads that produce lint and drivers with no dust covers. What could possibly go wrong? I wonder how the warranty would work on these. Do you send them in to Koss in the usual way or do you have to go through Massdrop? If there is the usual lifetime warranty it might not be that bad... I still wouldn't though, until they get some dust covers.

    These are not the forums you're looking for. Also, get the Massdrop HD58X and save your money.

    I've said it before, but I guess it bears repeating... I have no idea why Sonoma Acoustics went with a Warwick Audio driver for their statement headphone, since that driver was designed to be a modular, low-cost alternative to a traditional electrostatic driver. They would have been better off with just about any other high-end driver, including off-the-shelf dynamic ones... but I guess you can't charge $5k for a system if you use plain vanilla dynamic drivers. Or maybe you can these days, considering the crazy prices everyone else is charging. The FR looks quite nice in Tyll's measurements, and I'm guessing there's a lot of nifty DSP work going on in there to massage some semblance of neutrality out of these drivers, but it's wasted effort that would be better spent on something that performs well in the first place. Hopefully if they do a follow up headphone, they'll use an actual high end driver.

    People have been spreading the idea that driver/ear distance with Lambdas doesn't matter and you can use whatever pads you want, and it's become common knowledge. I guess 10db of midbass hump and nothing below 50hz qualifies as great bass to people.

    RIP TB. Pretty much the first youtuber I ever seriously watched. The gaming industry is today just a bit worse off than it was yesterday.

    I'm also impressed with the Gilmore Lite Mk2, got mine a few days ago. Clean, smooth, transparent, very nice with the HD650 and Focal Clear.

    I've emailed Stax in the past and gotten a response in English. So either someone speaks it over there, or Google translate does. But the sad truth of being a small company is that you never have enough time, people, or money to do everything that you need to do. So them simply not having gotten around to translating everything, or not wanting to spend the money to hire someone to do it, is pretty understandable.
