Pros: They sounded okay while they actually worked as Bluetooth headphones.
Cons: The rechargeable batteries in both pairs failed to recharge very soon after I bought them. Obviously, if you can't recharge them, you can't use them as Bluetooth headphones. I already own a couple pairs of wired headphones, so I gave them to my kids.
Summary: i bought one of these but under the brand of Aluratek or something. It was alright in the beginning but now it just sucks. The main reason is that it broke in a few months time. One of the speakers just stopped working. Also, the build quality is pathetic. The whole construction is cheap plastic with almost no metal except the screws. The sound is low end which isn`t surprising with its price.
