Pros it has the clarity superior to px-100 and porta pro
clean treble and balance mid
soft, jolting bass
no need for amplifier
foldable and pocket-friendly

Summary " colorful "
Pros Rich, warm and detailed music that sounds just as good or even better than my portapro
Better build quality with no hair snagging
Isolates noticably more noise than the portapro with its larger pads
Easier to drive (lower impedence)
Cons Bass is a little strong but that can be easily fixed by tweaking the equilizer
Larger pads may lead to hot and *sweaty* ears when used in hot and humid conditions
Heavier than portapro and a wee bit more uncomfortable with more pressure on ears
Summary I was a huge fan of in ear noise isolating earbuds till last year till I listened to my friend's Portapros. This led to an instant conversion. The music sounded so much sweeter with the absence of the annoying chord noise with in-ear earphones. The main drawback was the virtual lack of noise isolation. I bought the portapro and was really happy with it untill the driver soldering and audio jack started failing. Moreover, there was some rubbing noise as the cable rubbed against the driver casing. The poor cabling was the thing that forced me to retire the portapro after only one year.
I looked for a replacement and was considering the Sennheiser PX100 and PX200 along with this model. Reviews mentioned that the PX100 sounded superior to the PX200 but it cost AU$99 which is a lot of money for what is suposed to be a low end Sennheiser. Moreover, many users complained about the poor cabling/soldering which was the exact problem I had with my Portapros. The porapros are an insane AU$130+ (at time of writing, 1AUD can be bought with ~USD0.90). I turned my attention to this model which had a store price of AU$129 but managed to get it for AUD $99 since the store had a policy to match its competitors. The profit margin was definitely a lot slimmer compared to the PX100 and Portapro.
A reviewer considered this model as a Portapro on steriods. I can understand why. The music sounds more neutral than the portapro while still sounding warm, detailed and sweet. The design avoids the two flaws of the Portapros, namely, the hair snagging mechanism and the ball compression which is impossible to keep shut. The materials used are also of higher quality (not some dismantled leggo material). However, this model is not as comfortable to wear over longer periods compared to the portapro due to the higher pressure on the ears and more heat trapped due to the larger earpads. Would the cabling/soldering hold up better than the Portapros? Only time will tell.
Would I recommend it to someone owning a current portapro? Probably not given that the Portas are an absolute beauty (not visually) as long as they are working, but it sure is a worthy replacement if the Portas are grossly overpriced (as they are down under.
Pros Head Band Comfort, Ear pressure feels just right
Cons None so far
Summary I am presently in Bangkok so finding the Sony MDR V-6 is difficult. Did my usual internet homework comparing brands and visited Bangkok's upper end stores to try for myself. The AKG's were better sounding than The Sony's I tried on. Not too much Bass, Better fitting than the JBL 410's and very upfront and clean sounding. I am a musician with musician's ears and these headphones made me smile from the moment I tried them on.
