This headphone has a really good sound.
But... it is made with a "loose" cable with a mini-jack for headphone socket and a micro-jack for inserting into the headphone itself, and this is miserable to say the least.
You can barely turn your head without the connection in one channel disappearing.
After a few months of use, I took the consequence.
I took the left side apart (where the micro jack is inserted) and soldered a fixed cable on, and it now works flawlessly.
