One of the big issues Ive had with every pair of Sony headphones Ive owned is the aesthetic breakdown. The volume is static and depends on how high you have them turned up. Adorable product, especially for Adventure Time fans. The shoes are nice and sofe. When you just run drills you won?t notice the traction too much as i play indoors. So, would I buy them for their retail of £350? Not a chance. Blue lights blinked all night versus 10 minutes and shutting down per the manual. And I do mean PINCH! So soft, light, comfortable and they have pockets! You get what you pay for, I suppose, but I think it?s rather sub par.
