Poor quality, connection produces static

Poor quality. Used with a Chromecast Audio and "dumb" speaker. First of all, this cable cannot sit quietly -- during setup, without any audio, this cable produced static/noise/interference. I have another cable, under the same circumstances, that is completely quiet. With audio, the sound is dull. If I didn't have a side-by-side comparison, I might think this cable was ok. However, I swapped back and forth a few times and found this cable was inferior to what I already own.

I owned the old, non-xbox version of these headphones and loved them. They lasted for 4 years, and the drivers finally blew out. I bought these thinking they would be the same thing just with a new cable, but immediately noticed very loud static. Looking around on the internet and Razer's support site, it looked like the problem was bad USB shielding, but I tried many different power sources -- different USB ports, different computers, and several dedicated AC/USB converters (phone bricks). Nothing had any effect on the static. This is a huge design flaw with no workaround, and I would give this a big DO NOT BUY for any reason.

Gives static in picture. Not the cables - they work fine without this splitter.

I think I have a defective pair. There is constant static throughout the listening of music. I unplugged and plugged it back in to check if it was the connection, but it's not because it happens with my laptop too.

The picture looks really nice on amazon, but when you look at it in person, it looks really cheap (it's plastic-y).

Power adapter has a terrible hum noise and interference permanently.

I ordered this cable to connect between my DAC and headphone amplifier. Unfortunately, when it is connected it produces noise and static interference into my headphone which I never had anything like it with other cables. The noise problem seems to me something wrong with the soldering or improper grounding or shielding of the cable. No choice but to return it.

I had mine for a week and they broke. Lots of static and the quality is very poor.

cord goes bad / static prone after 3-4 months of use.  Second set to do this.  Cord is hardwired and cannot be replaced.

Lose connection, generates terrible noise on the line. Completely unusable.

Microphone quality on this thing is horrendous. I'm a tech savvy guy so I know what I'm doing and I get insane static from the microphone input on this thing. And "this item does not qualify for return." Buyer beware. If you need this for a microphone as well as a headset, look elsewhere.

Perhaps you get what you pay for, but this cable resulted in a very spotty connection, it does not work when fully plugged in, and experiences significant interference from nearby power cables. Not worth it if you really care about quality.

I bought this adapter a few months back and have had problems with it eversince. I connected it to my TV and powered up fine then paired with my bluetooth headset. It worked fine for about 20 to 30 minutes then started receiving a lot of static. I turned it off restarted but would not reconnect so I repaired it again and it did the same thing all over again. I have been trying ever since with no success I have 3 wireless sheadsets and none of them work with this adapter. All my headsets do the exact same thing that I have described they connect then the static after 20 to 30 minutes then won't automatically repair after turning off my headsets. I thought it was my headset at first until I tried my other headsets and now I realize it is the adapter itself as my headsets work with everything else that I connect to. Return date is expired' I had to give one star to submit this review!

While the fit and audio sound are good, there seems to be a problem with the posts making a good connection when plugged into any audio jack causing lots of static from the microphone ring. Have tried on  multiple laptops, tablets and phones. They have now been filed away in the junk earphone box. Would not recommend this product.

Connection very loose,  takes forever to charge due to bad connection

Power adapter attachment made a very poor connection with the unit itself, necessitating the unit to be wedged against something something for the adapter to make contact with the internals. In addition, the output quality was markedly worse than the composite signal itself, which flabbergasted me. I tried two separate TVs, two HDMI cables, and three different game consoles. Each made everything much blockier and blurrier. In addition, the sound quality was worsened leaving barely any bass and making highs tinny.

I might have received a defective unit, but for how cheap and flimsy the thing felt, I didn't feel like trying my luck again.
