Let me start by saying if this has been posted before, tell me where the other URL is 
My objective is to make a short review of commercial headphones/headsets/cans for use specifically on the K750/W800 phones.
I've tried two so far on my K750 :
1. JVC HA-E7
This is a 98dB sensitive headphones and requires about four steps (bars) to sound as loud as the supplied K750 headset. But if offers more detail and air to the sound, decent bass response but is muddy with MegaBass turned on.
2. Philips HP-890 headset
This is supposed to be a 102dB sensitive full-size headphone, BUT it sounds a lot weaker than the HA-E7. The sound is on the lean side when listening to this and really lacks power. Due to this I would say that this model is NOT suited for the K750.
I'm going to try the Sennheiser HD-497 next, as it was spec'd to have 112dB sensitivity.
If you have experiences to share, I'd be interested.

interesting topic...
but just one thing don't focus too much on the db sensitivity/response.
You should take into account the impedance of the headphones.
This is certainly the reason why the Philips lacks power...
The impedance for these is 32 Ohms. Which is not so high but try to stick with 16 Ohms headphones only.
I guess the output of the phones is not strong enough to drive high impedance headphones.
my 2 cents... |

you're absolutely right and thanks for pointing it out, but the JVC HA-E7 is also 32 ohms |

I'm moving your post here, so that we can collect headphone/headset information.

For home use I have some Sennheiser HD202's and they are excellent, but low powered. They are 32 Ohms, 115dB
They sound much better than the HPM-70 set, but the phone can't drive them so they are not as loud as the HPM-70's.
I am looking for an in-ear type headset, something like the Sony MDR-71 but with a short cable length. Pushing the proverbial up hill though - no one seems to make aftermarket headphones designed for devices that already have a length of cable with mike or remote and 3.5mm port on the end, hence needing a headset with only short lead length.

i don't want to start a discussion here, but sony's ex71 adn ex51 are hated for most of people of head-fi forum....
i've read a lot of topics and i'm still reading them to decide which earbud to buy and i'm among four:
- koss ksc-75 (not in ear, but according to a guy of head-fi's forum the best for k800 cause its output sound (of k800) is very hissy and this headphone compensates that)
- creative ep-630 (very cheap and well rated) most of people recommended them to me;
- v-moda bass freq (very bassy and cheap, not as much as ep-630, but cheap);
- marshmallows
now i have to chose one... very hard^^ |

that's because it's a sony! I agree that there are better but I'm happy enough with the HPM-70 but I just want something a little bit better (for mobile use). The HPM-70 is equivalent to the EX51 so by extension, the EX71 would suit that requirement.
btw, Creative are in the same class as Sony if you ask me, and in the low end of their range probably crappier, so I don't know what your head-fi guys will say about the creative ep630? Sony headphones are excellent quality but don't perform well on base unless you are using mega-bass (Sony headphones are designed to be used with megabase, one of thier disadvantages if you don't like thundering base or don't have a Sony device - probably another reason fortheir criticism in headphone forums)

so according to you sony's earbuds are made to be used with mega-bass function??? what's the point of sony doing that? for example, k800 doesn't have mega-bass function like walkman series, then i'll need to buy another manufacturer earbud if I want sound to perform better?

No the Sony headphones are still good headphones, but they are designed to excel at base only when megabase is used. As the post you provide says, the "screechy highs" of the hpm-70 don't compare to the "darker" base of the cs300's they are compared against.
Sony expect you to use megabase if you want "darker" base. Megabase solves the "screechy high" problem. However my view is that megabase is good but not excellent - it often creates muddy base. Whereas without megabase, Sony headphones are tinny but have good clarity and are excellent in all but deep base reproduction.
I'm not the only one who notices this. In a comparison involving Sony MDR E888 LP headphones, posted by coolvij at head-fi.org, I quote "the bass is fairly disappointing; no LOW bass presence, and a mid-bass without enough punch. Almost sounds like they WANT you to use Mega Bass (!?) - I don't, so.....there"
This isn't the only time I've read similar opinions about Sony headphones bass reproduction (and not just in the high end like the E888).
Infact the posts you link to support the idea that Sony is light on in bass reproduction. It's typical Sony proprietary practice, I don't find it surprising at all. Because it works in reverse too - without megabase Sony device base reproduction is not as thumpy as other devices. And non-sony headphones are too base responsive to use megabase (sounds muddy). Forces you to buy Sony headphones so you can use megabase to get decent base you see
btw, I've also read on head-fi that ex51 is more comparable to hpm-70 rather than the ex71, but I've never been in a position to do a direct comparison.
re: ep630, I've always thought of sennheiser as the high end, so I'm surprised that a "cheap" creative earphone could be a rebranded sennheiser, but if that's what it is then that's what it is. And sennheiser do have some cheaper headphoones these days.

now i agree with you^^, but in my case, that my cell doesn't have MEGA BASS (k800) it's better for me getting some earbud of another manufacturer that's not sony... |

yes I agree with that. I'm not sure why they dropped magabase from K800 other than because it's not a walkman phone. Bit rough, even my Sony pocket fm radio has megabase!
I may be wrong about Sony headhones but most of the pairs I've had seem to be crisp and clear in mid to high, but lacking bang and clarity in the base.
And megabase always seems to work better with Sony headphones.
btw, even though I said I was planning to upgrade my hpm7- buds to a better Sony brand, I wasn't saying it was the best option for everyone. I'm not particularly fussy, so I'm happy to settle for just a slight improvement over my current ones. But sennheiser (and perhaps the creative ep630 if they are the same thing) might be a better option and if they cost the same then why not. I'll probably have a closer look at them myself.

sennheisser cx300 is way better than the sony ex71. The ex71 is very shrill and it is intolerable IMO. Although the cx300 maybe a tad harsh at the high end, it's sound reproduction is better than the sony's.
the marshmallows are even cheaper than both and they have deeper bass IMO. But, they lack detail a tad bit compared to the cx300. I still like the marshmallows better though.
if isolation is not really needed, then go for the ksc75. In terms of SQ, it beats all these cheap IEMs to a pulp for about 20 bucks. And if you don't like the clip ons, then you can headband mod it for about 5 bucks.
right now i'm enjoying the yuin pk1... sooooo much better than e888s.
