The chips are nice and solid, the board is sturdy and has little rubber feet on the bottom to keep from sliding around if you bump the table. I havent used these for long durations, but with about 4 hours a day of active listening, I can go weeks between charging. cm899837 And they are super small the largest being no bigger than maybe 3" x 3". And 1 thing I couldnt believe is how heavy they felt. cm899837 The shoes are right there when I need them, no more shoes on floor and Husband is happy. cm899837 I previously bought (and returned) the m50x and 598cs, but I will be keeping the 599. Overall, pretty nice. This was a great read. cm899837 Everyones ears are different but I found these to be less comfortable than my Aircoms, also sold on Amazon. All other issues still exist 3 months later.
