Your products are near perfect. I've been looking for a very high quality Bluetooth music and intercom setup with full length boom mic. The SPH10 is great - I'd like to see a version that moves the electronics to the behind-the-head band, allowing earbuds to be hooked up and attached to the frame by the ears, which will still support the boom microphone. This would allow for noise isolating earbuds, as well as a slimmer overall profile. The electronics and battery pack behind the ehad would not bother me if packaged intelligently. Thank you.
