Rad said: I liked the SMS Sync by 50s. They’re comfortable and have good overall sound quality, especially with vocal music. But for a $399.95 pair of headphones, they have too many big and little problems -- the worst being the drifting Kleer signal and how little they masked outside noises -- for me to recommend them without hesitation.

Read the SoundStage! Xperience review.

The gist: Worth closer to 50 cents than 400 bucks.
