Replacement Audio upgrade HiFi Cable For Sennheiser HD4.40 / HD 4.40 BT / HD4.50 / HD 4.50 BTNC / HD4.30i / HD4.30G / HD400S Headphone Extension Cords

Review: Works with HD400s - I can confirm that this cables works with the Sennheiser HD400s headphones. It fits into the 2.5mm port and rotates/locks in just like the cable that comes standard with the headphones. I was having issues with the original cable when plugging into certain devices or extension cables, and this takes care of that. I got the 3 meter length cable, and now I can plug my headphones into my PC speakers and listen to music from my bed which is what I wanted to do all along with the HD400s. Lastly, I'll say the build quality matches the price. I wish I didn't have to spend $20 to get the full experience out of these headphones, but this cable is definitely an improvement over the standard one in all regards. The cable sleeve feels really durable, and the cable itself is surprisingly light and flexible. Two thumbs up for anyone looking to replace the stupid cable that comes with the HD400s.
Review: Sturdy and works as expected - EDIT: I apologise for the bad review. It turns out I was listening to YouTube while on a call, and the call was making the audio sound bad for some reason. The cable is fantastic; the audio sounds good, and it is sturdy and flexible. It fits snugly in my phone with no chance of falling out. Below is my original review, ignore that. That was purely user error. The cable works, I guess, but it's far too bad for me to say it's worth buying. The sound quality is TRASH. This isn't a defect with the headphones audio port, my HD 4.50 BTNC sounded great with the original cable. I would avoid this product

### ⭐⭐⭐⭐ Works with Sennheiser HD 4.50, including locking mechanism
*by A***R on August 31, 2024*

I'll keep it simple, the cable itself fits, works and seems well made. The included 1/8" to 1/4" adapter may not work for you. When I initially used it I plugged it into my preamp 1/4" headphone jack using the included adapter and only had sound from the right ear. Bummer. Tried it with a different 1/4" adapter and it works. If I use the included adapter, fully seat it, and then pull it out about 1/16", I then get both channels, so it may be my preamp. Tried it with the 1/8" plug directly to my laptop headphone jack and it also works just fine. Haven't tried it in a plane headphone jack, but I imagine it will work fine there too. The locking mechanism into the headset itself also works, but takes a little effort to get the plug to seat fully before you can turn it to lock, but this loosens up after a few uses. Not quite as good as the OEM but nothing ever is. All in all satisfied with the cable itself, not the headphone 1/8" to 1/4" adapter. YMMV as this may be my specific preamp jack not being compatible with this particular adapter.
