They are a decent size although I?m not sure why they all have a scuff mark on them?? I bought these for my son as a Christmas gift but I would have probably returned them if Christmas wasn?t next week. I have already saved money. Can also listen to music while I ride Do not hang it to anything. It needs a strong signal/soundcard so doesnt perform as well with an iphone but this is a computer headset after all. My boy loves them, please note the other Croc is woody so they dont look like a a pair still cool Thank you Cambridge audio for making an amazing and affordable set of wireless buds. - Sound quality is better than I expected. I recommend it for freshening items in between visits to the cleaners. Trick I didnt know is holding the side buttons down for 3+ seconds will put it in pairing mode.
