Even so, the headset is much better than what you can find in Dollar Store, or Below Five; and at least the same quality when compare to what you can find in the market for $10 range,Sound quality is not bad, no heavy bass - if you are looking for that :(Noise cancellation is done by good seal of earbud, I dont think there is electronic circuit for that. Connection is excellent, comfort is brilliant, sound quality is great and battery life is borderline infinite. Not ideal for sport (I used them on a spinning bike) since they get uncomfortable with the sweat, but its probably the case for all over-ear headphones. My granddaughter loved these, I would buy again, great price too! But I didnt do any gaming with them. My heel hits at just the back end making it very uncomfortable to wear. Please keep in mind that this item is the headphones only and does not include anything else - no transmitter / charger is included. Theyre made from a birki-flor (?) material that is essentially vinyl with a soft felt lining. This shoe is very comfortable. I may try to heat the plastic shields and bend them inward a bit to correct the issue.
