These headphones are able to bring you the full range of the piece from the most delicate entrances of the strings to the deep, powerful bass

Poor bass.

I jammed them into my ears trying to see if it was something I was doing and they lacked bass completely

The JBL quality you're used to, great bass and simple to use.

A little better range and more bass

There is good range and some good bass

For $70 these sound incredibly clear with crisp highs and excellent punchy bass that can handle the low 20's

Much more comfortable, and much better bass response (not as good as my old wired Bose in-ears, but decent.

Who shouldn't buy these: those who want slightly better audio quality, more bass, and features like noise cancellation.

The bass isn't very rich and overall the sound is a little washed out

I miss the magnet however, as the cord is very short and if you wear around your neck unplugged, you will lose them - as they fall off easily

I am amazed that they still work just as well as before I washed them

By contrast, the X3’s were difficult to seal and I hated the ear fins that had to be slipped on separately, and as such were more awkward to position and not as comfortable
