HUGE earbuds. They do block out outside noise though.
I'm using this as part of a &#34;ghetto&#34; in-ear monitor system (see the setup on Instructables). Other reviewers have had various quality issues, and I am in the same scenario. One speaker simply doesn't work. I'm perfectly fine with only hearing the monitor feed in one ear on stage, but I would be pretty mad if I was using these to listen to music.<br /><br />Other thing you should know: the earpieces are HUGE. I have a pair of the largest Etymotic earplugs in existence, and these are actually much larger! The foam pieces are the largest earplugs I've ever seen in my life, and they don't stay &#34;shrunk&#34; when you roll them between your fingers (though I haven't had any problem getting them in, despite the size).<br /><br />I need these for a gig, but after that, I plan to exchange these for another pair. If they are any better, I'll update my review.<br /><br />UPDATE: Got the new pair, and yes, this time both earbuds actually work. They're still ridiculously huge. At band practice, I can't hear anyone speaking unless they speak into a microphone, or I take one of the earbuds out between songs (not recommended if you practice with a bunch of &#34;noodlers&#34;).<br /><br />Considering returning these and spending the extra cash on the Etymotic earbuds, since I'm very happy with their other products.
