Koss - KSC35 Wireless

I use a KSC35 wireless as my travelling and I love them but unfortunately clip-ons are a dead end. Audio-Technica stopped production of even the EW9, and only Koss remains as the remaining maker of decent sounding ones. The only company even coming out with new models is Aune with the AC45/55. Even in asia the market has gone towards IEMs for portable use and full sized headphones for at home.

Koss excels at the 50 and under bracket.  The KSC35, KSC75, and Porta Pro are all well loved.

Look up Koss KSC35 or KSC75. You’ll save a few bucks and get top-notch quality. These are clip on but the sound is otherworldly, and they’re open enough. My musician friend recommended these.

The KSC35 Wireless is my go to for this.

Any closed over-ear headphone that sounds substantially more accurate than the S4R without going to exotic ultra-expensive vintage Stax? Maybe too much to ask for compared to those I put above it. The ESP-9 is awesome but HEAVY. DT1350 is on ear. Heck, the Koss practically is too with the shallow Koss pads. ER4S tier is too high a bar obviously for over ear closed. My headphones ranking goes something like: Stax 009 ER4S Stax SRS-2170 Koss ESP-950 HD580 Koss ESP-9 DT1350 Ollo S4R 1.1 DT990 Pro Sony MDR-EX15 (hard to rank these, actually) KRK 6400 K701 HD25 Ixos MOS DJ1001 Airpods 4 ANC Koss Sporta Pros and KSC equivalents Koss ProDJ100 Sony V6 & 7506 (bit too bright and glassy) Harman Kardon ANC Fly (too muddy but ok utility ANC headphone)
