Syba OG-AUD63048 NC-1 Cobra 2.1 Dual Driver Headphones with Built-In Amplifier and In-line Microphone - Retail Packaging - Black

They work okay, but the vinyl covering the headphones is completely peeling off. I bought these as a gift for my elderly father who is in a nursing home, and every time I take them off of him, he has black flakes all over him.

My father in law loves these as it gives him the opportunity to turn up the volume on the headphones as these headphones have their own internal amp. You can also adjust the bass, but the volume was his favorite function as other headphones were simply not loud enough for him to hear. They cover the whole ear and you just plug them into the USB port to charge them and the other cord goes into the headphone jack....these were one of the only headphones I found that had an amp built in at a reasonable price....

Good amplification. Bass a little heavy, and high frequency lacking some, but overall very please with the purchase. Being USB re-chargeable is a great bonus. Also like to good noise canceling. Great on a airplane with most any player.

Great sound, controls are not convenient tho
