I have a pair of JBL T460BT bluetooth headphones that cost me around £30 in the UK and they’re brilliant. Im my opinion, many headphones over $50 or £50 are very over priced and not good value for money. I use these mainly with my phone and the sound quality is very good with the dynamics just right and loud enough to enjoy the music without going to distorted levels and I can chat to my girlfriend on messenger when she calls me due to the built in microphone.
