Product arrived in perfect condition via Revain Prime. The headphones were originally purchased for decryption purposes, not for the intended purpose of gaming. I searched for headphones based on ratings, reviews and Prime compliance. The earbuds are a little bulky, heavy, but comfortable AND offer excellent noise isolation. The ear cups only adjust up and down and stay in place. Tested audio output at high volume and playback with Spotify Premium Equalizer. Bass output is a little lower, but the output is crisp and clear. Not recommended for music lovers or gamers who expect rich audio output. Flexible microphone. At first I thought the blue ring (on the speakers) would glow, but it's just one color. The headphone jack has a jack if your device supports both headphones. And a microphone in a connection. A headphone and microphone splitter is included. In general I recommend. Isolation also allows me to isolate my girlfriend when she is talking to me.
