The AF32s offer good clarity and deliver a good amount of bass. They also play loud and work pretty well with all types of music. MEElectronics talks about their openness, and I thought they sounded pretty open ("open" means that they don't sound canned). I did experience some listening fatigue after about 45 minutes, but you can switch to wired mode if you want.
Like the Creative headphones, these are by no means an audiophile-grade set, but I thought they sounded better than a lot of in-ear Bluetooth headphones I've tested and delivered almost as good sound quality as the pricey (also an on-ear model), which cost significantly more and aren't as comfortable to wear. I also thought they were superior to a pair of Jay Bird Wireless SB2TR Sportsband Bluetooth headphones I had in-house.
The MEElectronics set also performed better than the Creatives for making calls. The microphone is "hidden" in the right earcup so it's a little far from your mouth, but my test caller said my voice sounded pretty clear (especially indoors) and was impressed with the sound quality.
Finally, battery life is rated at 12 hours on a single charge, which is quite good and 2 hours more than the Creative headphones offer. I was able to use them for a full week on my daily commute without having to recharge (my total commute time for the day is around an hour).
The AF32 headphones offer similar sound quality to the identically priced Creative's WP-350 Bluetooth headphones. Both sound very good for sub-$80 Bluetooth headphones, but the AF32 gets the upper hand in comfort and sound quality. In all, these are very solid Bluetooth headphones for the money and I have no problem recommending them at this price.
