My experience with the QC30 has been really great. Noise cancelation is very good when the earpieces are properly fitted in my ear - better than my QC20i. The sound with music is definitely better than my QC20i's. Excellent separation, clarity and base.

Noise Cancelation quality and adjustability, Comfort, Mic during calls, Excellent Sound Quality, Connects to 2 devices, Bose Cust; Service

Neckband can rotate; BT connection is a bit weak sometimes

The good .SOUND IS GREAT,NOISE CANSELING IS TOP The bad..KLINPING IN VERY SHORT DISTENS,AND IN GYM BAND IS MOVING A LOT. Conclusing ..ITS NOT FOR GYM WORKOUT,Y HAT TO RETURN IT ..

If it were one or two sets that'd be different but FIVE!! Ridiculous! Great sound great noise cancellation but DO NOT FALL IN LOVE! And Bose Customer Service.... HA!! Not great at all!! Do not waste your money!

I thought its going to be the best headphones i buy but on the other had, it was not. my old Samsung level U quality is better. The microphone has issues I think, everyone i call cannot hear me well, so i had to switch to level U again.

Comfortable in ears Noise isolating great

Neck band slips around neck Bose updates are very poor Sound has to be turned up maximum but still seems low Not worth the money

Having already purchased the Bose Quiet Comfort, 35 series 2 - I felt living in London, I was almost saying "hey guys take this off my head", I never felt safe enjoying music at my leisure. The Quiet Control is well hidden.

Two things Just are unacceptable. The shocking telephone experience for the person on the receiving end of the call if you are in a noisy environment such as a coffee shop, and the awful Bluetooth range.

The quality of the product is amazing! I love the quiet control, it is super useful in common transportation but also to study at the university around loud students... However it is super annoying not to be able to connect them with the computer, they should seriously do something about it !

"Noise cancelling is amazing and sound quality excellent. Also very light, perfect for travelling. Design could be improved but overall very pleased. " Show More

You can already tell if this iem is for you by looking at the pros and cons. I personally use it a lot due to the sake of convenience (rechargeable battery, noise cancelling, wireless) and it gets the job done. I might give this a five stars had it been priced $150, but every Bose overcharges.

Battery life; noise cancellation; convenient

Price; audio quality is only ok
