They technically worked, but sound bad (lots of static, barely fit into the socket on the headphones, and felt very cheaply constructed. Do not try this for astro a50'sI had a set of Turtle Beach X11's sitting around that I had been unable to use on my Xbox One for a few years now. I was constantly trying to figure out a way to rig them up so the mic would work with the One, but to no avail. The game audio worked just fine with them because it comes from the optical port, but the mic would not. I found these cables were really low price, so I figured why the heck not. Got them, plugged it into the bottom of the X11 inline switch, plugged the other end into the 3.5mm port on my Xbox One controller, and VOILA!!! It worked just like it should. Pretty happy with this. The only concern I have is how thin the wire is. I'm wondering how long until the tiny wires inside it start to break. Especially with my 14-year old son using it, too. I guess that is one reason I got the 3-pack. LOL Anyway, works like a charm. Get it if you have X11's that you haven't been able to use since the 360 days.Bought this as a replacement cable for the Astro A50 Gen 2 and Turtle Beach PX4's. Fits perfectly for the PX4 but it's quite snug on the A50's as rubber part of plug is fatter than port on A50 (thus, you don't hear the plug snapping into place). However, once you have it inserted, it works just fine. Had the plug been slightly thinner, it would've been a perfect fit.This cable made my Astro A50s sound quality terrible, I had to trim around the plug just to fit my Astros, and the first cable I used broke in 2 days, I guess that’s why they send you 3. Just buy the correct Astro Cable, buy once cry once.Works wonderfully with the Turtle Beach headset that needed a replacement cordIt worked perfectly for our turtle Beach headset so my son could play with it on his Xbox one he was very happyI lost my original cord this one works perfectlyWorks for connecting my old turtle beach X12 ear force (made for Xbox 360) to Xbox one controller with adapter. No static, clear voice going in and out. Went to every store I could think of except a radio (because I don’t think they exist anymore) trying to finding a 3.5 mm to 2.5 mm jack and finally ordered online and hoped it worked. Fulfilled its purpose.Funciona excelente en Astro A50 Gen 1
