User Review: For the past few years, I've been using Sony earbuds.  I've used the EX51s, the EX71s, the EX75s, and am now using the EX300LPs, which are by far the best that I've had.  The bass response and the dynamic range of the EX300s puts them in a class by themselves.  Compared to the Sony EX300s, the Logitech Ultimate Ears are good, but they don't come close as far as the sound.

However, the Ultimate Ears do have some real strengths in terms of features.  First of all, the cords are thicker and more durable than any of the Sonys that I've owned, and this is definitely a plus.  Many users have complained about how quickly the Sony cords deteriorate (I've had this problem on the 71s), and the Ultimate Ears don't look as if they'd wear out easily.  Secondly, the Ultimate Ears designate the right earbud with a subtle red color that you can see when you put them in, but that doesn't show when you wear them.  This is a much smarter design than labeling the earbuds with a tiny "L" and "R" that isn't easy to see.  Third, the Ultimate Ears come with a small, easy-to-use case that snaps shut and is just big enough for the buds and cords, without taking up too much space.  Finally, for people who don't like the Sony design which has the cord loop around the back of your neck, with a short cord going to the left earbud and a longer one going to the right, the Ultimate Ears offers the standard front-hanging cords with equal lengths for each bud.  It also has a slider that lets you adjust the height where the cords divide, allowing a good fit. However, the cord length is not quite long enough to put your iPod on an elliptical trainer while working out;  you'd probably have to keep it in your pocket.

Both the Sonys and the Ultimate Ears come with three sizes of slip on earbud covers, and both fit very well.  I didn't feel that either was better than the other in terms of staying in, since both have to be shoved back in if you're working out and start to sweat.  For other listening, the buds on both stay in without a lot of trouble. The Ultimate Ears' user guide that you can insert the earbuds after looping the cords over the back of your ears, to keep them from falling out, but I found this to be very uncomfortable and it looks really dorky, too.

I like the Ultimate Ears, and in many respects they are designed better than the Sonys, but they simply can't compare when it comes to sound.  I'd say in terms of sound, they're  a lot like the Sony 71s, not even quite as good as the 75s.  Since the EX300s are available for about $60 including shipping, they're a much better deal.
