I agree that there is a genuine need for a "set minimum BPM" feature. I also very much like the wireless suggestion.

May I also suggest improving your audio quality? It is currently (perhaps) on a par with an AM radio. It should be improved to at least FM quality. Further, if you used stereo, you might even make subtle use the left and right channels to help differentiate inhale and exhale tones.

The wireless capability and improved audio quality would likely increase power requirments, so an A/C adapter would also be appropriate.

All good points. I have to agree with wanting to see a wireless version, in this day and age I think it's almost a given!
I like your ideas. Our R&D needs to hear more ideas like this from our consumers!
Keep it coming guys!
Breathe Easy!
