A promise is a promise! Here are some pictures of my new headphones (Sorry for the bad quality of the pictures)
Price: I've paid for them about 138 dollars.
Sound: Really nice and detailed. Clear highs and good bass for open headphones. Particularly great for the sound of guitars. Yamaha says: "Created to convey the authentic sound of every musical instrument." And that is what you get with this headphones, they sound pure and real. They sound like ' everything is under control '
Soundstage: Very good but as you might know, it could vary quite a bit from track to track.
With a correct song - for example: El Choclo - Juan D'Arienzo 320kbps - soundstage is just amazing.
Built quality: it's good, nicely made. I think for the price there are some other headphones better built, but despite of this, built quality is not a problem here.
Confort: As some Grado headphones you have to find the way you prefer to wear them. This are not the most comfortable headphones in the world, just comfortable I must say. I use them to listen to music for an hour and a half, often 2 hours with no problems at all.
Driver Type: Dynamic, open air
Driver Unit: Φ40 mm (1-5/8”)
Impedance: 48 ohms
Max Input: 1,000 mw
Sound Pressure Level: 98.5 dB ±3 dB
Frequency Response: 20 Hz – 20 kHz
Weight (without Cable): 180 g (6.35 oz)
They don't need amplification, an ipod is enough for them to be very enjoyable.
This are really equilibrated open air headphones. Mids and Highs are excellent and bass is also present in enough quantity to let you enjoy bass, mids and highs at the same time.
PS. I read some reviews of people saying that this sounds better than Grado's sr 80 and sr 125 and quite similar to Grado sr 225.
I would like to try Grado's sr 225 some day to compare.
Update (7/19): Since I did this review, I've been listening and comparing very different headphones and I think I have aquired some extra experience with sound.
After all I have to say that nowadays I enjoy my HPH-200 as much as always, every time I put on them.
The sound of this Yamaha HPH-200 is, at least for me, more on the 'lively' side of neutral (rather than flat). They have some extra energy between 50Hz and 500Hz and then they sound warm and have good impact. They also have some extra energy around 8500Hz wich provide good attack and brings some cymbals to the front.
Its soundstage is not the biggest, but is still very nice. Instrument separation is very good, and timbres are really convincing (IMO)
More subjectively talking:
This headphone demands your atention, especially when playing good recordings, maybe this are not the best choice if you are looking for a completely polite and neutral sounding headphone to sit and relax while an orchestra plays for you. But this headphones make you feel in the middle of the band. I find their sound really engaging.
I never get tired of listening to Procol Harum live in Copenhagen and At the Union Chapel with my Yamaha HPH-200.
Right out of the box they sounded very good but often quite agressive with some recordings. After one or two month of use bass notes become more present and their highs less agressive.
