Well, I just got my D66 eggos in the mail, I’m wearing them now. So it’s time to wrap up my impressions of the Philips HP170s.
The Philips HP170s are about $20 at Target or off of the internet.
The Philips HP170s are closed headphones of a size best suited for home use. Isolation is moderate to low, probably due to the inexpensive build quality. Isolation is not as good as the eggos, and about half that of the MDR V6s. Isolation is much better than with an open headphone, though.
Build quality of the HP170s is silly. They’re cheap plastic. There’s a big headband, with a support under it. Two very light silver plastic big globes, one for each ear. They have a stereo and mono switch and independent left and right volume controls on the earpieces for making them compatible with some kind of broadcast that I know nothing about.
Comfort is light and excellent. Comfort is better than the eggos, for example.
To me, for sound quality, the HP170s smoke the following headphones so bad it’s not even worth discussing: Sony MDR-CD580 (too bright), Sony MDR-CD180 (boom, echo, sibilance), Sennheiser PX100s (high end is quite limited), Koss KTX Pro 1 (same), Sony MDR-605LP (dull and cold).
The coloration of the HP170s is as follows:
Bass quite enjoyable but definitely in excess of neutral, but not so much that it degrades the midrange.
Mids prominent, silky smooth and pleasing. A bit breathy. Vocals and brass and reed instruments sound awesome.
Highs a little in excess of neutral. But the brightness seems to start at around the very top of the midrange, so instead of a cold MDR V6 type sound, I get a really silky smooth exuberant pleasing sound, with both musical instruments and voices.
The HP170s have a unique sound. I’ve not heard anything similar.
Compared to the Grado SR60s, they have more bass, a silkier midrange.
Compared to the Sennheiser HD 497s, they have more bass but not as clean, more prominent and open and less pinched or nasal sounding midrange, and stronger highs.
Compared to the Sony MDR-V6s, they do not go so deep in the bass of course. Otherwise, they don’t have that cold sound, the mids are much more prominent, and the brightness seems to start at a higher frequency and extends higher, in a more pleasing way.
Compared to the Sony MDR-85s and the AKG 240Ms, the HP170s have more bass, more mids and more highs. How did that happen? I dunno.
Compared to the Koss KSC-35s and KSC-50s, the sound is more bass, more highs, silkier and more prominent midrange. And the HP170s are much more practical, IMHO... just throw them on.
Compared to the Sennheiser HD 580s, they are much more exuberant but less neutral. But even though I find the HP170s exuberant, I do not find them fatiguing at all.
Overall, the HP170s are probably not too close to neutral. But I love the comfort and I love the sound. These are the best things I’ve heard for $20 by a long shot. These are good, cheap, closed, comfortable headphones, for real. As a total package, for my listening pleasure, they hold their own with anything else, and they’re quite unique. They have a strong, involving sound that takes me into the music very quickly.
And they sound VERY different from the eggos, BTW.
