Sennheiser PX 200 II B Closed on Ear Mini Headphones

This is my first pair of on-ear portable headphones. I've had a bunch of CX-series in-ear phones and the cable always broke. So I wanted something on which I could easily replace the cable.
They're very small, could easily fit a larger pocket, they also fold nicely. They're also very nicely built, the materials are of good quality.
The sound is balanced, maybe a bit shy in the highs, the bass is not boomy and overwhelming like on most consumer headphones and the mids sound very natural.
They're confortable enough (actually I quickly forget they're on my head).
Overall a good purchase. Hopefully I'll be able to easily change the cable when it will go bad (cause it will).

I’ve been looking for a replacement for my Sennheiser PX200 first generation. I’ve had them for over 10 years now and the ear pads and padding on the headband are severely deteriorated.
My criteria were: highly portable, closed design, comfortable, natural sound. Max. € 100,-
This forum lead me to a bunch of alternatives from AKG, Beyerdynamic, Audio Technica and some other models from Sennheiser like HD228. This thread http://www.head-fi.org/t/433318/shootout-113-portable-headphones-reviewed-alpha-design-labs-adl-h118-added-07-15-14 was my starting point.
During the last year I’ve tried about a dozen of these that I fit my criteria.
Bottom line: I bought PX200-II and am more than happy with them.
They are indeed an upgrade and tick all the boxes that the previous version left open More characteristics: good, but not too much lows, good highs and a nice midrange without the coloration you normally get with this type of small headphones. If you look carefully, about all components are redesigned. Another improvement is the single lead design. Nearly all competitors lack that.
If you looking for headphones with identical criteria, then take PX200-II into consideration. There is really only one thing to check: you’ve got to get a good fit, otherwise you won’t get enough bass. This means that you have to try them for yourself.
Furthermore, these have a volume control in the lead, which is IMO useless. Maybe you’d better go for PX200-IIi if you plan to use some sort of i-device. That way, you also get more functionality.
They are not perfect, but for me these are the best I could get for this kind of money.
 
Cons they share with every closed portable headphones I've tried: missing top end (tingling highs), heat build up after some time.

When i got these, i was chuffed. i read from reviews saying they were good, so i had high hopes. fortunately, these cans definitely delivered  They look nice, and are really small and light. Comfort is a bit lacking at first, but when you get used to it, it gets better. Also, they are relatively affordable. Build quality is great, expected from Sennheiser. isolation is average, but what else do you expect from a small, sealed, pair of cans? Overall, the sound is good. The highs are slightly rolled off, but are smooth and never fatiguing. The mids are slightly boxy, but satisfactory nevertheless. the bass was a weak point of the first px200's, but because they now have a better seal, they're tight and weighty. Overall sound signature is balanced and natural, and soundstage is better than you expect from a headphone like this.
conclusion: Great value, and a brilliant all rounder. if you need a everyday headphone, definitely consider this as an option.
