The textured instep makes standing comfortable, plus you can easily slip your foot out for a little relief or a little air, then back into a comfortable shoe. For comparison of the K701/K702 to the consumer headphone reference level, the AKG K701/K702s 105 db SPL at 1 V into 62 Ohms translates to about 93 dB SPL at 1 mW into 62 Ohms. I know it comes with 10 different adapters but why not just make a model for each brand instead of giving me 9 pieces I don?t need? Not very impressed with their product. I ordered the yellow in my normal size and they fit perfectly! It was easy to mount and we have had no trouble mounting four adult bikes. They?re very comfortable, stay tight in the ears, and have good sound quality for the price. I was certainly skeptical, but thus far, it?s held up just fine. I wont ever buy anything from this company again, for the disrespect to US Citizens. Glad I sized up!
