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...

I own two Lasmex L-85 headphones. My impressions:
Build quality is stellar: smooth metal and high-grade plastics used throughout. They have and open-back design, with less sound leakage (out) that most open-back headphones. Comparatively, a fair amount of outside sound is let in.
The L-85 stock earpads' openings are too small to encompass normal-sized ears, so they would be classified as having an on-ear design. Fortunately, the pads are easily replaceable. To improvement comfort and to sound-stage width, I replaced the stock pads with various Brainwavz Earpads.
Unfortunately, the L-85's frequency response is drastically V-shaped, with a wide bass-to-lower-mids hump and too much treble. Using Brainwavz protein leather earpads installed, a FiiO Q1 mkII DAC/amp, and a free Windows program called Equalizer APO, simply copy-paste the following into the 'Edit text' bar of the Graphic Equalizer:
GraphicEQ: 30 0; 35 -5; 40 -7.5; 45 -9; 52 -10.5; 60 -11.25; 70 -11.75; 80 -12; 120 -12; 160 -11.75; 200 -11.5; 250 -10.75; 315 -9; 400 -6; 500 -3; 630 -1; 800 0; 1000 -0.5; 1500 -2; 2200 -4; 4000 -6; 20000 -6
In iOS (iPhone, iPod, iPad), the Pop , Lounge, or Treble Reducer presets are suitable.
Brainwavz Hybrid Earpads improve the airiness of the sound. I configured this profile with them installed:
GraphicEQ: 20 0; 25 -4.25; 32 -7.5; 40 -9.5; 50 -10.75; 60 -11.5; 70 -11.9; 80 -12; 100 -12; 160 -11.75; 200 -11.25; 250 -10; 315 -8; 400 -5; 500 -2.5; 630 -1; 800 0; 1000 -0.75; 1500 -2.25; 2200 -4; 4000 -7; 20000 -7
And finally, on another pair of L-85s (that have less bass and treble than the first headphone), I installed Brainwavz Angled Sheepskin Leather Earpads and configured this profile:
GraphicEQ: 21 0; 25 -3.5; 30 -6; 36 -8; 44 -9.5; 53 -10.25; 65 -10.75; 80 -11; 120 -11; 160 -10.75; 200 -10.25; 250 -9.5; 315 -8; 400 -5; 500 -2.75; 630 -1; 800 0; 1000 -0.75; 1500 -2.25; 2200 -4; 4000 -5; 20000 -5
The driver used in this headphone is likely the one discussed here: https://www.head-fi.org/threads/lasmex-l-85-headphones.817590
In summary, the Lasmex L-85 is a well-constructed, value-conscious headphone with capable drivers. With some initial effort (pad exchanging and customized EQ applied), they can be transformed into an absolutely superb headphone that will compare favorably to more expensive models.

Now I'm curious to find out if a pair of HD6XX (with or without EQ) sound better than my EQ'd L-85s with angled Brainwavz sheepskin pads installed. The HD6XX scales well with higher-end DAC/amps - but is limited from lower-end amps. So that could be an important aspect to consider for prospective buyers of either headphone.
Nevertheless, I guarantee my L-85s are more durable and comfortable than the HD6XX. Plus, the Lasmex earcups fold 90-degrees (in both directions), and it uses a standard, singled-sided, 3.5mm connection - not a double-sided proprietary connection like the HD6XX, which is really only beneficial if running the headphones in a balanced set-up.
I find these to be pleasant enough even without an EQ, but it is great to know that my ears can tell a V-shape curve.
I invite you to try-out my EQ correction for these. Curious to hear your thoughts on what it does to the sound.
