bought fiio eh11s because i could not resist the novelty for $40 shipped, but honestly these are just awesome. zero compromises and the sound is surprising for the price. tuning out of the box is questionable as many others have reported (apparently it is trying to replicate the porta pros?), but the builtin eq can clean this up nicely. if these can have an on-device eq, there is no excuse for any other pair of bluetooth headphones.
