Customer Reviews

SMS Audio Headphones1/30/2013
Good looking, Comfortable, Loud, Bass isn’t overpowering, price lower than Beats
Adapter range isn’t 50ft as advertised.
Other Thoughts:
For those who didn’t like those headphones cause of noise cancellation, it doesn’t have it. It was never advertised to be either. These are not noise cancelling headphones.

Love me sum 5010/1/2012
These are the best headphones I ever had. Better than bose, skullcandie and Beats. I love the sound and the wireless feature is just insane!!!

Freedom from wires6/26/2012
wireless with anything!
sounds good with most things
wish it was a little clearer
Other Thoughts:
The Sync is an incredible advance in wireless technology in the audio business. You’re free of cumbersome cables, which is awesome. I bought it to use while walking and commuting. It is very very good for these purposes, tho i wish it was a little bit brighter/clearer?
Overall I’m very happy with my purchase. More companies need to incorporate this type of wireless feature.

Sync by 501/22/2012
the sound quality is really good, and a lot of features.
It doesn’t cancel noise at all. You can hear whatever happens, and doesn’t feed the ears sometimes (Studio is more comfortable)
Other Thoughts:
It doesn’t cost 400$, and will not recommend to buy one. The worst is noise cancelling!

Best sound quality and great durability...
Other Thoughts:
Every single headphone lover should definitely get these.

Good buy12/28/2011
Sound is impressive, very sharp.
I had to send mine back for an excange. My sound would cut in and out from time to time. Forward and back buttons to not work. On most apple and Comp devices. An upgrade part will be out in Jan.
Other Thoughts:
Looks damn good.
