Personally, I treat wireless earbuds as essentially disposable items. Even if they're mechanically reliable, they fall out on a ride/run, they fill up with earwax, and are otherwise way too vulnerable to invest hundreds of dollars on.<p>The sound quality of $30 Bluetooth earbuds from no-name vendors is plenty good enough in the terrible acoustic environments I use them. If you want good sound quality, no earbud is ever going to come close to a good set of full-size headphones, so I'd prefer to invest money in those instead.<p>Yeah, active noise cancellation would be nice but I imagine that the next generation of cheapie earbuds will have that too.<p>While I get the desire for reducing environmental impact, the total mass of these earbuds is so small that it hardly seems worrying about in terms of the millions of tons of crap that goes into landfill every year.
