Slightly fiddly to recharge, but they work well and the sound quality is good. I cannot confirm how long the battery lasts but I used them for about 40 minutes without any problems. No complaints, as expected. Warps a little if you sway your front wheel side to side and when the crank is all the way into the stand; you cannot get a full rotation with the pedals or else they will hit the stand. Cos, completely neutral headphones are awful for bog standard listening. So this is my first time buying a Chromebook and Im not going to lie for the price its actually worth it. love the price and the sound quality Nice quality backpack but small. The depth and shine are amazing! Such a shame, as they are very comfortable for the time they are still in one piece.
