I bought this because im a frequent music listener i like to hear the good thump and those sweet 808's so when the specs said capable of 20hz i just wanted to give them a try and they work. You're getting what you came for but the problem here is that there is leakage from the ear. the design is not meant to be in the ear and that makes sound come right in. when im running or in my car all i can hear is the road and my own steps. It also muffles the sound and the bass is unhearable not to mention the bass is not what it says. It's actully roughly about 34-36hz and up. none the less decent headphones for its price.

The cable is longer than seen in the product photos, They droop far below the ears, looking silly. One can insert the earbuds upside down and lay the cable behind the ears, but this is a compromise and the cable will easily fall. I believe that James B. Lansing would have directed that the product supplied match the one in the pictures.

No doubt, the sound quality is great. I'm using it from 2 weeks and comparing to my other few brands, I'm disappointed in 2 factors, the battery should last for a full day at least but this hardly is up for 6 hours without continous use. Secondly, they haven't provided any rubber cushion of small, medium and large size with the earphone and it is losely fixed in the ear. Difficult to stay while in the move.
