S0 is the new little brother of S5 which I quite enjoy. It costs about half the price of its big brother, at US49.50. It's great to see more competition in the sub-$50 price range, because that's how much most mainstream consumers are willing to pay for a pair of good earphones/in-ear monitors.   S0 has the same flat cable as S5, which may take some time getting used to compared to the traditional round cables. There's some microphonics even when worn over the ears, but adjusting the cinch upwards makes it a lot more bearable just like S5.  ...

Design and Comfort S5 is a new higher-end in-ear-monitor from Brainwavz retailing at about US$100.  I’m glad Brainwavz has offerings at most price points below $200. It's great that companies such Brainwavz and SoundMagic help bring down prices; if not for them, we would still be paying an arm and a leg for these things.   It has a flat cable instead of the normal round cable, similar to the new Creative Aurvana Live! 2. I don’t know if this is a trend. I’m more used to round cables, but round cables do tangle a bit, except really thick ones like...

Sound Quality Straight out of the box, it sounded great, pretty much like the original CAL!. I’ve done over 100 hours of burn-in. DAC is FiiO E10. As I mentioned in one of the posts, it reminded me a lot of Sennheiser HD 25-1-II. This can be a headphone for people who really appreciate bass (bassheads included).   Is this a neutral can? No, but it is definitely a fun can with a V-shaped signature. Most people on Head-fi claim to prefer neutrality, but the truth is a V-shaped response is perceived to be more balanced due to the equal-loudness...

Miscellaneous:   They came in a tube-like container. There are only three pairs of silicone tips, although they are quite comfortable. The material used is softer than that of PL-30’s. The housings are open at the back so if you use them on the go, there would be wind noise coming through.  As I have grown accustomed to over-the-ear designs, an ear glider would have been nice, but at such low price the accessories are reasonable.  The only difference between MEElectronics M2P’s and M2’s is the P version has a built-in microphone, useful for when...

Miscellaneous: They are exceptionally comfortable and light; when I wear them I sometimes forget they are in my ears. The quantity of accessories is more than enough, though the quality of which is not so. The tips seemed poorly made, and one of the bi-flanges even has some defect. I only found the olive-like foam tips to sit snuggly in the ear canals. Isolation is above average with those tips, but the sound would be darkened because of that. The cords tangle quit easily such that I had to separate them almost every time, but this problem improved...

Miscellaneous: Brainwavz M2 is the repackaged version of ViSang R03 with identical IEM component. These are quite comfortable, but they are not light per se. I also decided to (carefully) cut off one-fifth of the length of the long strain-reliefs. The accessories include three sizes of hybrid tips and three sizes or foam tips (they are similar to olive tips). I am happy with the medium size for both; however, the small foam tips are so small that I can’t think of any adult would find them fit. It would have been better with a spare pair of either...
