    These are some nice over ear phones, lower priced but sound great. I got these for my wife who has a tiny noggin and she loves them, I have a big ol melon and they feel great, so kudos there.
    The manual they supply is… challenging but not impossible.

    Finally got an opportunity to pair them with my phone. Wonderful sound, full and clear the mic on the headphones are real sensitive to sound it picks up the sound of my typing on the keys while I’m working. I don’t have a problem with though. I really like them. 👍

    These headphones have a great floor, and are easy to connect. The sound is much fuller than I had expected. However, the only drawback is rhat the ear cups are slightly smaller than I am used to. It’s not a bad thing for me since my ears are small, but it may be a problem for larger ears.
