Dear all,

Guys I had K750 for few months. I got it with HPM-70 bundled with it. Since the first day i have been using the phone with HPM-70. I was a S700 user and i was happy with its sound and camera, etc.

I use convergence hand phone primarily for entertainment, especially music. Music quality is very important to me. I tried many Nokia S60s and by surprise most of them produce mono output (3660, 6600, even the latest 3230). Even stereo output at 6630 considered inadequate, at least for me, for musical enjoyment. I tried 6230 also (at that time, and later 6230i) but the quality is the same. I don’t like Nokia stereo system, i think they use different DSP chipsets. Well, maybe i just have to wait for N series.
S700 came as a savior. Yes it is heavy and a bit bulky, but sound quality is great for hand phone. Yes it can't beat my PDA Tosh E800 with GS Player installed but it is replaceable enough for daily use. The only complain for me is the volume level is abit low and the accessories connector the stereo headset has (HPM-20). It gradually loose and become unreliable. I changed the stereo headset two times in almost 1,5 year with S700.

Later i have K750. The first time i tried the HPM-70 i was amazed about the cool design, beautiful emblem, bass reproduction, and the 'rubber'. I red many threads here about the unusual way to use the headset (by plugging it deeply inside your ear), and i chose the best rubber ear bud for my ear size.

Somehow there is something missing from the stereo quality. I don’t say that HPM-70 is bad, it just sound different. I heard many songs with it and i think it doesn’t have enough dynamics to make the sound heard as i expected. Sometimes i miss my old S700 sound.

I gave HPM-70 with K750 to friends so they can try, and beside the "oooh" and "aaah" answer that i got, most of them told me that the sound is great. For a time i think maybe it’s just me and my ear, which have to adapt to this "new" headset.

HPM-70 have very strong character reproducing the bass resonance. It can produce deep and heavy low frequency very well, especially if you use the correct "rubber ear bud". But it came at the price that sometimes it misses the high frequency (treble) noticeably.

And just yesterday i misplaced my HPM-70. And i have no other choice but to use stereo headset came with my K750 package that i left unopened. Surprise, surprise, this is what kind of stereo i have been looking for. It sounds like S700's stereo but better in resonance and dynamics (probably due to different chipset and larger size of that 'tiny' speaker).

Finally i found my 'sound' again! I cannot believe it, but i have to tell you all, K750 is best to be paired with its bundled headset. No need to try everything else.

Some notes though. I don’t have chance to use other headphones attached with HPM-70. This headset gives us facility to change headphones. I think i will try later. I don’t have the chance to try W800 either. But if both hardware systems are the same it should reproduce the same sound that came from K750.

Maybe (with assumption above) SE software engineers have doing their homework well. They have tweaked K750's firmware so it can match best only with its supplied stereo headset. Logically also the same thing happened with W800. Heck, maybe K750 and W800 have completely different DSP chipset at all, I am not sure.

Maybe i have defect HPM-70 unit, not physically but the way it produces sound. It might sound strange, but i have this kind of experience with S700 stereo headset, HPM-20. I have to buy one more time because i think the first headset i bought produce different sound than the original that came with package.
And SE service center don’t repair accessories especially if they see the headset is physically 'fine'- although at least they admitted to me that both headset sound different. They just told me that ‘that was a minor variance’ resulted from mass production and not covered by warranty.

But I cannot just buy another HPM-70 if it is just its original sound character (beside of its price of course).

For make the matter worse, the supplied stereo headset that came with K750 package is not listed at official accessories web page. I can’t find its code name. It is like HPB-60 but have dual speakers. HPM-70 is the only stereo headset listed there to use with new connector.

I want try W800 with K750 headset and see this difference. For a while that HPM-70 will go inside its package.

Anyone have other experiences?

PS : just if you noticing the ‘L’ and ‘R’ mark on K750’s stereo headset I think it had been misplaced. The left should be on the shorter side, while the right on the longer side. The sound quality is at best at this position.

Yes, that what i've red on this forum, but my experience is bit different.

Stereo headset supplied with K750 definitely better than HPM-70 that i have.

Ooh what a story! One thing i can tell u is be carefull with headset from k750, threat it nicely, the durability is not good, i've got 2 pair (i lost my 1st k750 and i bought again another one) and both were broken. One has a broken on left earpiece, another one on the right. Perfect huh since i cant get a replacement on here (indonesia/bandung) and hpm 70 is not available yet.

my opinion is that you definitely a defective HPM-70 if you reckon the bundled handsfree kit provided with the K750 is better.

its like saying a 1.1 ford fiesta is quicker off the mark than a ferrari enzo. (well a bit of a bad comparison, but you get the point)

That should be an input for me to buy another hpm-70 then. Or at least until i can find someone who can lend me the headset for a while.

perception and definition of "soundquality" is based on individual preference. Its not a scientifical fact.

Scientifically perfect soundquality is a perfect reproduction of the sound exactly as it was originally recorded, not biased by anything.
Neither dsp's, ad-converters, equalisers, speakercomposition or anything.

But most people have their own preference as to what sounds good, some prefer an emphasis on bass, some prefer an emphasis on trebble, some prefer an emphasis on stereoperspective. Most people doesnt really prefer the "correct" unbiased neutral uncolored soundreproduction.

For some odd reason, most people seem to define soundquality as how loud the bass level is, typically you see this in most youngsters carstereo, and in the adaption of the "megabass" choise in the equalizer of K750 and other players, and in the HPM-70's emphasis on the basslevel. This may sound best to many peoples ears, but its definately not "correct" or better soundreproduktion.

Point being:
It doesnt matter how many people or reviews say the HPM-70 is "better" than the standard headphones, as it depends on personal perception of how the sound should be. The standard heaphones easily reproduce the entire frequencyspectrum possible to hear for the human ear, just like the HPM-70, and therefore anyone saying they prefer the sound as reproduced by the standard headphones over the HPM-70 is very valid. Just as those prefering the sound preference of HPM-70 are valid. But saying that HPM-70 is better per say, is simply wrong.

The only speaker/headphone that is best for you, is the one which defination and reproduction of sound you personally prefer. No matter what any reviews or other opinions may say.
