So far a great pair of headphones that are pretty inexpensive to me and they are pretty nice and kind of durable even though they are made out of plastic... I like them they feel snugg and are really nice because they are adjustable and you can adjust the ear cup parts! The leather foam feels really soft and comfy and I saw a video of a guy taking the headphones apart just to see what they are made of and they look decent inside... So far I've had them for a few days and they work really really well! The battery is AWESOME I really believe that they do have 20hrs+ to last up to 15-20 hours because in the first day that I had them I charged them up and used them that whole day and they didn't even decrease in battery life. The next day I wore them and I watched a show that has hour long episodes and that didn't drain the battery and I didn't see a little bit of a decrease until today and it wasn't even halfway! They were still above halfway so these are the best headphones and I'd definitely recommend them! Thanks for the awesome headphones and for the price they are a steal! I hope this is helpful I thought that maybe these wouldn't be great but after buying them and using them I'd definitely recommend to anyone wanting a cheap pair of headphones that's last a long time in battery life! Be careful though because of the plastic material it may be fragile so use the carrying case! But the headband seems pretty strong so I don't see a problem which is usually how most headphones break but these look pretty good! Thanks for reading have
