I used Sennheiser cx 180, 275s, Creative ep530, Apple earphones, JBL CS200SI and Sony MDR XB55AP, EX155 in the past. I didn't like CX 180 at first when I moved from creative ep530, as the bass was not good. But later realized that I was using incorrect size earbuds, after thar it was awesome earphones. Only drawback was lack of mic. When CX180 stopped working after 3 years, chose 275s, but disappointed with the bass , and there was no workaround. But it was good to listen music. Once I lost it , I tried many other earphones such as sony XB55, EX155, JBL CS200. Sony XB55 having too much bass overpowering vocals and treble, have bigger size. EX155 overpowered in treble. JBL CS200 has good bass and treble, but cause pain to ears after 1 hour of usage. So, chose Apple earphones. When It got damaged , tried CX 180S after checking so many reviews. Sennheiser CX180S sounds better than other earphones in the market. There are too many reviews complaining about the low bass and volume. But I found no issues in these aspects, only trick is to use the right size earbuds. Otherwise, these earphones don't sound good. Aslo don't use any equalizer settings, keep it in normal mode. Sennheiser CX180S bass is very good, it gives the thump ,not distorted nor treble oriented bass. All the instruments and vocals very crisp and clear along with thump bass. It is very good in watching movies. These earphones provides good noise isolation if right sized earbuds are used. We can barely hear the sound of nearby vehicles or people. It also don't hurt the ears even after hours of usage, thanks to soft earbuds. Drawback : Price should have been in 1500 range, no volume adjustment button. Missing pouch. Read more
