Sony DR-BT21iKB Wireless Headphones


Control your iPod from far away!

The headphones are much more lightweight than similar models. They offer great levels of comfort. iPod controls are available on the headphones

Low bass range, some edges are sharp and uncomfortable for some users, signal wanes when you are on the other side of a wall from your iPod

This comfortable headphone set fits snugly on your head as you listen to your music in high quality. It also connects easily to your iPod via wireless to allow you to listen to your favorite playlists.

Good, but not great.


For bluetooth the sound is great. i can hardly feel them on my ears anymore. however to do this i had to wrap gauze around the frame above my ear because it was fairly sharp there. Mine were refurbished but nothing is wrong with them as far as i can...

Great Sound! wireless freedom, lightweight ;

Comfort above the ear, doesnt work well through a wall ;

I wish I had found this sooner


I'm an A/V guy -- "A/V freak" would be more appropriate at times. I waxed and waned over buying this for about two weeks and finally did so about two weeks before I deployed. I think it is the best set of headphones I've ever had. Not only can I listen...

The Best


The product was more than I expected. I bought the headphones for my workouts but now I use it for all my daily duties around the house. I have no problems with the volume because I found the switch on the headphones. I can control my ipod from the...

Good product


I also use this when working out the gym and on the subway, but my one issue is that it doesn't get loud enough and I sometimes can't hear everything despite cranking the volume all the way up. (I'm not hard of hearing, it just that surrounding noise...

Nice wireless headphones for your iPod


If you're looking for good quality wireless headphones, look no further. This product does exactly what it says it does. The sound quality is excellent for wireless headphones and yes, it will work from 30ft. This feature doesn't actually excite me...

Does exactly what the product information says it does

The headphones disable the volume control on your iPod, requiring you to control the volume from your headset
