Treble: There is some nice energy in the lower to mid treble area and everything sounds very sweet and almost soothing at lower to moderate volumes. If you?re expecting the normal high quality bushacre 2 I?d avoid this pair. Its charges my iPad gen6 very well for not being fast charge capable. Seems to do the job. The battery life is fine as well. In terms of noise reduction--they perform well for audio-book consumption, considering that my routes are along busy multi-lane roads in urban San Francisco. Cute sandals but the leather is very stiff. I purchased several of the 4? & 6? dock lines. I dont worry about loosing my grip and having them snap, like a rubber band, and potentially harm someone or something near me. Right size right width perfect.
