I repurchased these yesterday after returning initially and I agree with the sentiment of others that these are simply excellent sounding buds. I've tried the B&O H5, Freedoms and am currently using the Jabra Elite Sport for workouts. These Bose blow them away in terms of sound quality, fit and comfort. Sound quality in particular is impressive. I originally returned these for the QC30 which CNET referred to as a "noise cancelling version of the Soundsport" but I was not impressed with the QC30. The sound profile is different on the QC30 and I much prefer the Soundsports. I agree with AppleRobert that these are the best sounding BT buds on the market if you can accept the somewhat low max volume and open design neither of which bother me.
How is the comfort of the soundsport compared to the qc30? I want to get the qc30 but the neck thing really bugs me and I can't really justify 300 dollars other then the active noise cancelling
