Review on iJoy ISO Wireless Over Ear Foldable Stereo Headphones with Bluetooth 5.0, 30-Hour Battery, Built-in Microphone - Black/Red by Chris Cooper

In the end they are worth your money. The bass is decent and the mids are great. Will they sound like $350 Beats Studio phones? no But for $30 you probably won't find a better one. The noise cancellation is fair, as with most entry-level phones on the market. The main downside (and it's significant) is comfort. 30 minutes is the longest I could wear. They are too heavy for their size and don't fit as well as they should. The battery life is very good. Charge it once a week and use it for a few hours a day with no problems.
