With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.
Not the same guy, but I don’t have trouble blocking outside noise with Etymotic ER3SE earbuds. They do go insanely deep into my ear though.
Mine also get quite buried, like earplugs. And they’re still comfortable.
And damn, yours must be really nice at that price!
I got them on sale for around $110. They might be expensive for wired earbuds, but still cheaper than nice wireless earbuds, including the Fairbuds this post is about. Also, the cables are replaceable in case they ever get damaged.
