The Technology Curve is getting steeper!
Something you didn't suggest in 'your daily use description' of these devices was a comment about 'what percentage of the Day' were these things useful? I'd say that I'll wear my LG Tone for 90% of my working/waking hours, I have a ( never been used ) back-up.
Shure are making a headset using their 215 but also able to use their 535 and 846 in-ear monitor.
Geez, I see this segment getting some Style Attention, hmm, how long before they're on the Front Cover of GQ, being worn by Anderson Cooper or someone else, doing: Product Placement?
I still have uses for my wireless Sennheiser headphones but for how much longer?

ps.. Onkyo & Pioneer have just released little Digital Audio Players with MQA, these devices seem like having an entire 1980s front end music system in the palm of your hand ( include having TTVJ's entire 12,000 vinyl collection on SD memory cards ) phewwwww.
ps.2, those Europeans, like Goldmund & DynAudio, are getting serious about going Wireless & Active.
