Here are the features I'm looking for:
1. The advanced pairing properties inherent to Apple phones with Apple Airpods.
2. wireless - without an extra compression/decompression layer
3. Great battery life
4. Great charging case, very compact for my travel kit, ideally multiple charges for a 1 week trip. Having to plug stuff in all the time is a bore...
5. Sound like my high end Shure earbuds.
6. wingtip attachments that make a nice fit
7. sound isolation (unlike airpods now)
8. a system to allow you to hear outside noises when you want.
9. apple technology being created where it doesn't matter if you put headphone in left or right ear, it figures that out on its own and switches inputs.
Apple Airpods + Shure is what I want. This would be a serious winner.
