Sennheiser PC37X randomly goes bad after disconnecting the cable ?
Greetings, Yesterday I was using my headset like normal with my macbook, just listening to music and on a call with people like usual, and the headset was perfectly fine. The stock wire that came with the headset is extremely long and yesterday it annoyed me very much that it kept getting tangled with itself, so I decided to see if the cable is replaceable. I pulled out the cable from the headset and saw the adapter, and looked online for a replacement. Upon plugging it back in, the audio sounded extremely muffled and washed out. Im not sure what I did wrong to make it mess up like that as I've always taken good care of it, ive had it for about 2 years and its always just been chilling on my desk, but anywho I thought the cable just went bad and ordered a replacement. The replacement came, and the issue is still persistant, so I am not sure what the issue is I've tried multiple different headsets and the issue is not with the port, and I also tried it with my windows laptop and...

So what does that mean for audio? Well Aptx can transmit over bluetooth up to CD-quality (16-bit / 44.1kHz) if both devices are aptx. As mentioned earlier, if one of the devices does not have aptx, then it will go back to Bluetooth quality.
AAC can only transmit over Bluetooth up to 256 kbps. Which means that it is much lower quality than aptx. So what are the benefits of AAC? Well the benefits are mainly for compression of audio. So an AAC compressed audio sounds better than an MP3 audio file at similar bitrates.
For wireless, than Aptx is way better than AAC. Which is too bad that Apple doesn't support it.
PLEASE NOTE: AAC does support higher than 256kpbs, but Apple only currently sells music at 256kbps. There are rumors that they will eventually start selling higher quality than that, so in theory AAC can stream higher than that, but we'll have to see in the future.

Technically, CD-quality (16 bit/ 44.1kHz) isn't lossless either, though to be sure better than AAC. In my situation, I have a modest CD collection, a smattering of HD tracks (thanks Lynn Records 24-bit days of Christmas!), but the vast majority of my music library is AAC anyway. iTunes supports importing CD's into AAC at 320 bkbs already, it would be interesting if those files played natively... but ultimately just having AAC in Bluetooth headphones is a boon for practically my whole music library and portable use (storage/listening environment). When I'm at home to appreciate the finer differences in master-quality audio, I have higher-level wired headphones and a whole DAC/amp setup to support it.
I posit the challenge that almost any background noise (office noise, conference, train, cars, etc) will destroy any benefit from anything encoded at greater than 256 Kbps AAC.
