Apparently one of the biggest difficulties in getting truly wireless headphones to work is the human head, which is why companies like Bragi and Earin are having problems with their products.
Geoffrey Fowler, Review: Truly Wireless Headphones Arrive, But With a Few Strings Attached
Earin and Bragi have accomplished leaps of technology to make earbuds truly wireless. The problem is our heads. It’s not just that they’re hard; they’re full of water, which stops wireless signals dead.
Earin’s solution uses familiar tech. Made by a Swedish startup, it connects its left bud to your phone via Bluetooth. That bud then uses special antennas to bounce a second Bluetooth connection off walls and other surfaces to the right earbud to complete the stereo pair.
It almost works. Earin’s right bud cut out often enough to be annoying in my tests using the latest iPhone and Samsung Galaxy phones. The problems mostly occurred outdoors, where the Bluetooth signals can’t reflect off walls. On my 30-minute test runs, the right earbud typically cut out for a split second three or four times. Some early owners have reported a much worse problem with dropouts, judging by BestBuy.com reviews.
I bet Apple will figure out a way to engineer around this problem.
