So, without any extra room, everything. After a couple of months = 2/10. For some reason, I just do not "feel" these shoes exactly. They were comfortable to walk around in and protect your feet from whatever may be on the ground. I already have the W-KING 50 watt bluetooth speaker for outdoor use and was looking for a more compact bluetooth speaker to have around the house and also as a backup to my outdoor speaker. First, the whole thing smells. 5mm to 1/4" adapter. But this fits perfectly. The sound quality is amazing for a speaker so small. They?re easy to use and connected to my phone within seconds, overall really love these
