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: 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
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.
