Customer Reviews
JBL? Worth every penny - and much more comfortable than youd think!,
So, lets be clear. JBL have been innovating audio technology since the beginning of the last century, ergo, theyre NOT some fly by night cheap Chinese firm producing knock-off goods to make money off gullible punters. These Bluetooth Headphones are among some of the best made on the planet (for the price youre getting them for) - and years of innovative technology have gone into them. They DONT have noise cancelling technology built into them, but they DO sound as good as some headsets costing over twice as much. Theyre built quite solidly - certainly NOT flimsy. Im using them with my iPad mini 4 and iPhone 6s Plus - and they work flawlessly. They clamp quite well onto your head, so you wont loose them while jogging. You can make or receive calls with them too. High quality music sounds fantastic, and theyre not TOO bassy, but the Bass is certainly there. It hasnt dropped a Bluetooth connection yet, something my £300 Bose QC35 headset invariably does without warning! You could buy a lot worse for the money. These are meant to be my walk in the street BT headphones - didnt want to be mugged for my Bose QC35s by some brazen moped muggers. These JBLs do the job and do it well. p.s. My top of the range Japanese car also has a factory installed 9 speaker JBL audio system. I absolutely trust the technology, and Im pleased with these bargain priced smartphone compatible BT headphones. Surprisingly, these do not hurt me ears after prolonged use! :)
