Pros: extremely articulate high frequencies, makes older songs sound alive and way more detailed, brings vocals clearly to the foreground

Cons: NOT FOR BASSHEADS...if you are used to Beats by Dr. Dre or cheapo earbud they'll sound tiny and squeaky to you...try some Sennheiser HD 202 II instead...once they break... try these so you'll enjoy all the details missing from other earphones

Overall Review: Cheap armature headphones make great portable AUDIOPHILE companion, extremely easy to drive, I don't need to carry an amp to get good, detailed sound from my ipod/smartphone

Got the wrong merchandise delivered. Called multiple times for 3 months and still cant merchandise returned...useless costumer service.
