The bass is like Wow, the noise cancelation I had my TV usually blast and didnt hear . Still it manages to block some low frequency repetitive noise. The top thong is looser than youd see on Reef sandal (like for fatter feet). They sound great, with a rich, vibrant quality to their audio reproduction. It looks smart and works really well. The sound across all spectrums is improved but I must caution that , if you update, you cannot roll back to the old version. I had a very similar pair my grandma gave me a few years ago and I loved them. I have bought a second one for upstairs. Ao verificar, alguns dados não bateram com o original, fora estes aspectos de qualidade sonora, número que se encontra abaixo da borracha de encaixar no ouvido. Bottom Line: For me they a better than average headset for a great price.
