: Not many- one of few avialable when first released
: Mediocre fidelity, lousing design for staying sealed in ears
When I bought the Nokia BH 505 there were not many choices for stereo bluetooth headsets. I liked the head band idea but this design with the slightly flexing headband always popped the buds out of the ears and broke the isolation making it lousey to listen to with all the ambient sound (and sometimes noise) interfering. I gave them away just a couple months later.
