Good comfortable headphones

It is difficult to find a decent pair of wired head phones. The sound they produce is balanced. You don't need to increase the volume to enjoy the music.I would have liked better noise canceling.When I buy wireless phones , I will consider this brand.

Okay for the price

The headphones are cheap and durable. It is great to wear to the gym and doesn't fall out. Best part is that the pricing makes it so I don't really care if they break, but seems durable. Sound quality isn't the best but still gets the job done.
