For the price these are not bad little headphones. I do not listen to my music at the max, so have not had any instances of leakage and angry stares from people around me. What I did notice was that I had to turn off the equaliser on my phone, which made the sound a lot clearer. I am not audiophile so cannot comment on if the sound quality is due to the wood or not, but for me they have good clarity and the right amount of bass.
My only concern is the tangling of the cable and wondering how long they will last before something breaks. Time will tell, but if you are after a cheap pair of headphones, then I would consider these.
