-I thought the slightly bigger size compared to the G305 wouldnt be a big deal and it kinda isnt but its still a bit of a problem since it restricts me with vertical movement and horizontal movement to a lesser degree. This speaker has 30W of speaker and it definitely shows. Like a fuel gauge in a Ferrari, the battery will deplete VERY fast while streaming or with WiFi and BT enabled. The fit was good, however the plastic strap rubbed on my inner arch in a very uncomfortable way so I had to return. The bottom cushioning is nice but its ruined by the tough leather straps that roughly dig into the top of your feet when walking. The installation is a bit tricky but I managed! Its colour is soo soo cute soft pink, but one ear cord working one not So I bought a pair of my own and I absolutely LOVE THEM. But overall satisfied with all of the color variety of beads Once I got the skin on once it got scratched it shows white and makes it look ugly.
