"Airpods – a Speculative Teardown" by Nick Hunn a GREAT read!
Adding to all the ballyhoo around iPhone7's missing headphone jack is Nick Hunn's "Airpods – a Speculative Teardown" blog post. Boy, a sharp mind is a beautiful thing to behold.
Blow-by-blow, he "reverse imagineers" Apple's new wireless EarPods detailing:
- How they might utilize A2DP and BLE (Bluetooth Low Energy) to coordinate the two EarPods and remain compatible with other phones.
- How audio quality is enhanced mostly by stronger radio signals.
- How the shape of the EarPod enables a lot of this cool stuff to happen.
- How and why the charging case is likely smartened up by the W1 chip.
- And most importantly: A very detailed list of what the W1 chip might include and why.
I like to post guesses...this guy seems really good at it.
What he didn't speculate on is why Apple permitted themselves to continue to produce it in acoustically an ear-bud design. Ear-buds (intra-concha earphones) sit in the bowl of your ear and don't make a seal with the ear canal. This is the worst type of acoustic coupler configuration of all headphone types. It just doesn't seal and looses bass....and that's what all the kids want. (Me too.)
My guess is Apple doesn't want to deal with the all the different earphone tips and the discomfort of IEMs. So they stuck with the crappy acoustic seal and the W1 chip has enough DSP capacity to do some corrective EQ.
Guess I'm going to have to get my hands on a pair.
