There's tons of bluetooth earbuds on Amazon that you'd never hear about but are top ranking sellers in their category. I've bought 5 different pairs over the last 3yrs and they've all been great (I lose them or buy them for other people).

They all sell for $30-60 and are the same quality as Amazons.

It's like how Apple is the #1 phone seller even though there are 5x more Android phones in circulation under 10 different brands.
