Ha I get you, I tend to have a low opinion of Apple products so I try to temper my assumptions and ask questions about the products with an open mind.
Hm, my understanding is that this combination of positives wasn't especially novel in the wireless headphone market. Was it?
As far as the design, I tend to think Apple has historically excelled at design, to the point that my favorite phones aesthetically have been shameless Samsung rip-offs of iPhone designs. But I don't see this reputation lived up to in their last few products: eg, the square Apple Watch is a lot uglier than the contemporary (at launch) round Motorola offering. And I personally find Airpods to look like hearing aids; I was recently in the market for high-quality Bluetooth headphones and the Airpods' hideousness is part of what knocked them out of the running.
Also, the size is key. Hearing aids keep getting smaller and less visible while continually improving at varying performance metrics, and airpods represent that technology starting to impact the consumer market.
The case with a battery, seamless pairing, great battery life, reasonable EQ, and iconic style made them a smash hit.
