I was kind of amazed with these.
£13 for a pair of decent sounding headphone (but i’m no audio geek). Not great. But… and its a HUGE but …
These cheap little headphones come with noise CANCELLING, not isolation (they have that too), but actual black magic cancelling that you normally pay £50+ for.
And, it works, so yeah. Not a bad deal ! Oh and they have a inline microphone, so you can use the with your phone to make calls. Not bad at all.
