I’ve bought these air dopes 1&1/2 year back . They are so awesome. Till date i’ve never faced a single issue with them. The sound quality is soo good. If you charge them up for at least 1-2 hours you can use them for a long time(you can watch a minimum of two films of length 3hrs/can listen to an youtube tutorial continuously for 5-6 hrs).If you are looking to buy boat’s best air dopes under 1500/- then this is the best deal for you.The design is so could that your ear wont get hurt, even though you use it for longer hours.So I highly recommend this product
