My only gripe with these is that they are loose. Its not worth trying another pair because this will always be a weak point in the design, and Im not willing to risk that a new pair will last only a little longer, and then I wont be able to return them. It isn?t flush so it rubs my little girls feet raw. Sound quality is pretty good for a pair of beats, better than solo3 I find, not too bassy for beats but still extremely boosted. El sonido mejora usando los tapones auditivos que vienen incluidos, pero se pierde el objetivo de no tener nada dentro del oído. However, I paid $72 for it but the tag on it said $60. The only thing to be aware of is that the foam is not as thick as the original stock foam in the Beats Solo 2. To be honest i mainly play the hode mode something very satifying about killing many zombies. Living in the midwest this was the first time I rode in over 3 months with winter being here now . The sound and battery seem to be the same from the previous version to this, though im sure there might me be some minor upgrades im not aware of.
