To the point: EXCELLENT earbuds. My experience with this product has been great. For what it's worth, I'm a professional recording engineer. Does it make me an authority on all things audio? The answer is NO!If you're reading this review, then YOU are going to be the expert. Hearing for the most part is like fingerprints----everybody is different, though there is some common ground on what sounds "good." The sound quality is very well-balanced in these earbuds. Good bass, mids, and highs. They're going to be good for all around music listening during the workout, sitting at the airport----anywhere within reason. Critical listening? Would not be my first choice, but then these earbuds are not made for the studio. Don't expect the starship Enterprise when flying a paper airplane.Don't expect to tune the loud outside world out----go to Bose for noise canceling. These buds are touted as, NOISE ISOLATING. I personally feel this is a catch phrase to make the consumer look twice, but I can tell you as long as you seat these earbuds with the right fit of the several choices of supplied tips, you're going to find that the "isolating" quality is fairly good at moderate volume levels, and even better when cranked up----no brainer there, but keep in mind ear damage.I find these buds to be quite comfortable with long periods of wear, both in and out of the ear. The '"memory" loop that goes around your ear isn't spot on, but good enough to be "worn" in with only minor adjustments every so often, and stay in place with a lot of movement - jogging, biking, and other similar activities.The case is a nice touch and is not junk. I believe, as with most things, if you take just some obvious care i.e. use the case, don't wad the buds up, don't get them wet, etc, these will last a long time and deliver good, if not great performance for a long time.Bottom line----grab 'em. You can afford another pair if they get lost. At this price grab a couple of pairs. I did, and for my workouts, or tucked up under a helmet, these earbuds are a great deal that deliver great performance without paying a premium for much more expensive models.Hope this helps!
