Now for 100 $ you have nothing ... This statement is not quite true. For a small fee you can still afford a nice sound, comfortable, sturdy headphones that offers good performance ... but beware, it is necessary to sort.

2- Audio Technica ATH-WS55 

For less than 100 $, the ATH-WS55 from Audio-Technica find takers, it no doubt ! It delivers dynamic sound while remaining clean and balanced, with well positioned midrange and treble released but not aggressive. Despite the label Solid Bass, Audio-Technica avoids the pitfall of "Noise Cancelling" helmet. A good mix that allows a pretty good versatility in the WS55. The only point that may need to be improved, it's ergonomics (single-sided cable, a touch less pressure of the bow, true folding mechanism).

3- AKG K 518    

The AKG K518 offers a good price / quality ratio for eclectic music lovers who's looking for a helmet more than just a headphones. Provided large circular 69 mm headphones, the AKG relatively well isolated from outside noise. Overall, the K 518 delivers good sound quality, although the sound reproduction can be a bit nicer for some songs. 

Quite elegant with its range of 7 colors available, however it can be uncomfortable to wear over time. Comes with carrying case and with a long string of more than one meter, the AKG K518  proves quite convenient to use and convenient to the greatest number.
