I went on a large audio setup 'training' course in which I learned nothing I didn't already know. The dudes there were suggesting that on loud audio systems (large PA) mp3s sound like garbage and only lossless will do. "Garbage in, garbage out" they repeated whilst playing noisy lossless recordings of badly recorded and mastered music.

I didn't have the heart to tell them they were clueless and that when you're playing poo poo that loud, the room you're in makes far more of a difference than that of a 320kbps mp3 and a flac.

Dude also totally didn't get what I meant when I asked about their sub placement which was under the tops, which 99% of the time is the worst possible place for them.

Question: Has anyone else noticed that the left and right audio channels are swapped?
Answer: I just tested and you are correct. Tested on Windows 8.1 with balance controls and with left/right test mp3's. It would seem that this product is fatally flawed.

If anyone was curious I just bought this last week and my audio channels were properly oriented.

Did have an issue though under Linux where going below ~25% volume would flat out mute the USB audio channel. Easily fixed though.

I both own and operate a pirate ship.
The place I used to work used 5/8" or 3/4" thick Canadian MDF for speaker boxes. Unless you got a bad batch it was hard and would take machining and leave a hard edge. If it was crummy then it would be a bit softer and leave a fuzzy edge. Once we got a load of boxes made in China for some reason and they were made of 3/8" MDF that was so soft you could leave marks in it by hand, aside from the lovely workmanship they were made of garbage. MDF smells bad and makes dust that will kill you, but if you get the good stuff it's a great material for speaker boxes.
Also once we got a load of MDF that was made from corn stalks and when cut it smelled like french fries. :v:

It's a Linear tracking turntable and this particular one can be mounted to a wall. I never had it in that configuration though.

I don't have that one anymore. I have a different linear tracker, a Technics SL-J33. It's not wall mountable nor is it playable in vertical orientation. But it looks cool and that's why I have it.

Looks like it could be a real thing:

quote:

OAEs and hearing aid fittings.

The concept behind this lies in the ability of OAEs to identify regions of the cochlea with damage, which can assist in programming a hearing aid. When OAEs are absent, we assume hearing loss of greater than about 25 dB HL at the frequency where the emission is absent. In difficult to test patients, or any patient for which we cannot obtain audiometric threshold data, the absence of an OAE gives us some idea of hearing levels. In conjunction with ABR, we can use this data to program amplification for these patients. Absent OAEs in conjunction with audiometric thresholds of 70 dB HL or greater can be an indicator of a cochlear dead region, which in turn can influence the hearing aid selection and programming.

http://www.audiologyonline.com/articles/otoacoustic-emissions-beyond-newborn-hearing-838

So it seems to make sense, but I'd argue that high quality components and two way system, the psychological effect of the calibration process and the weird fit would have more effect on the perceived sound quality than the correction by itself.

They're probably getting testimonials from people who've never used decent headphones too.

Would be interesting to get an example of a user's set of corrections and see just how much effect it's having.

The physical device itself is completely pointless, an in-ear monitor can already provide much better deep bass than a conventional set of headphones.

If the doubled noise isolation is important, just use IEMs and a wear a conventional set of ear defenders over them.

Individual calibration is a good idea, but there's no reason to use a specific set of gimmicky headphones for that. Samsung has had an "adapt sound" feature on their phones for a while, you calibrate it by listening to a series of tones at different frequencies and identifying whether you hear them in your left or right ear or not at all. It actually works surprisingly well, so I imagine a more in-depth version of that should be able to increase perceived sound quality.

Olympic Mathlete
Feb 25, 2011

I'm intrigued to see what happens if the headphones decide you should be listening to a certain EQ and you don't like the EQ... "yeah but your ears and your brain WANT you to listen to it like this" Essentially they could force any old lovely EQ in, probably don't even have to have any electronics in them, if they adjust per user then each set is going to sound the same to you no matter what, right? You've no actual way of telling multiple pairs apart... Shroedinger's headphones, are they doing anything or not? How can you tell?

It has to be something stupider than speaker cable towers, and that's probably peak stupid so far.

Something like "Passive disharmony absorbers", little passive devices you mount around your listening room that will absorb any disharmonic sounds and prevent them from being reflected. Obviously they would cost three-four figures each and for optimum sound quality you should have at least one per wall and one in the ceiling.

Speaking of snake oil (i.e. most of this thread), I recall there being an article a while back where someone bought one of those ridiculously expensive "power conditioners" and cut it open, revealing that it was literally nothing more than a cheap cable inside a fancy-looking block of wood. I've tried to google for it, but I can't find it any more. Does anyone know the article I'm talking about?

I am a fervent proponent of a properly implemented volume-dependent loudness function.

Boost the bass and treble (or cut the mids) at low volumes and gradually back off the EQ as the volume control is turned up, ending with a completely flat EQ at around 80dB SPL.

That's how it actually works in a lot of old-school stereo amps, but you have to turn up the volume way too far before the EQ is completely flat. But that's why the best vintage amps have mute functions to cut the signal by 15-30 dB. With my Akai AM-2600 on -30 dB mute, loudness on and bass dialed back two clicks, the loudness is absolutely perfect through my JBL 4410s.
