The bluetooth range is good compared to other wireless headphones I have tried. Its a very professional studio condenser microphone and I do not think you would notice a difference from using this microphone versus a $3,000 microphone. My husband said he could he me very clearly when I was talking with him, and I could hear him perfectly as well. I always struggle to find comfortable sandals and have spent a fortune in the past in the search for the perfect pair. I will come back to this review in another month for update. They do not create that large of a profile from the front. Or the corridors bluetooth disco bulb. Well written and fast moving. Cushion is average. I enjoyed the X but I feel that it didnt truly live up to the hype, however I did grow extremely accustomed to my Apple Watch.
