Sound quality of the Samson Z35 is superb. Clean and flat sound signature, but powerful, fairly deep bass extension, crystal clear mid-highs, very clean, well-defined sparkling treble. No spikes, no surprises anywhere. Very real presence and convincing sound stage.    Fit is very comfortable, real leather ear cushions, which do not get hot & sweaty at all (so far - been listening to ambient/trance on and off for a few days). Initial head clamp force is fairly high, but loosens up after a few days of listening. Inner head band is soft, pliant...

They just work. Nice, clear & flat-sounding (nothing in audio spectrum particularly stands out -  a good thing, if you want to approach "analytical", which these things most assuredly are not).  Listening to 320 kbps ambient tracks on internet-radio.com right now.  Very immersive, good sound stage / separation.   Very Comfy fit, using large silicone tips. No cable noise. Decent build quality.   Excellent bargain at Amazon.com - $9.45 USD.  What's not to like?   These things garner 4.4 out of 5 stars among 38,316 reviews on Amazon.com, which has...

These are just plain excellent.  I was never really a believer in IEMs, but I am now. These Philips SHE3590s are a real eye-opener.  According to the ratings here on Head-Fi, these do, in fact, out-perform some of the $400+ kit...and I am not surprised.  The main complaint regarding sound quality seems to be a slight lack of clear, natural highs/treble (kind of artificial-sounding). I agree somewhat, and I experimented with my laptop's B&O equalizer by rolling back the Philips' 4 KHz and 8 KHz regions down to -2 and -3 db respectively, and boosting...

Just got these, and right off the bat they're very impressive.   Full, clear sound, plenty of energy & balance throughout the entire audio spectrum, with slight humps in the 20 - 100 Hz region (+3.5 dB) and from 6 KHz on up to 14 KHz (also around +3.5 dB). I flattened these right out with Peter Verbeek's excellent APO EQ system. Everything sounds very natural and clean. Sound stage is also very well delineated - especially for a completely closed design like this. Isolation also very good.   50 mm drivers, neodymium magnets, 10 Hz - 25 KHz...

Transformative, in a big and positive way.  The perfect, finishing touch on my Panasonic RP-HTF600-S phones...makes them look almost high-end, and they certainly approach it, in sound.  Most impressive.   Was skeptical about all the hype surrounding these velour pads, but now I get it. I really do. Amazing audio improvements, and hours on end comfort.   I'm even going out on a limb here...but it's the truth:  I heard some of the reviewers here say that these Panasonic RP-HTF600-S phones are so good that they gave them chills, and almost made them...

Bought these last week off Amazon.com for $34.  Right out of the box they sounded great to me.   Was never a believer in "burn-in", but now it makes sense;  headphones have drivers, which are essentially air-moving diaphragms mounted on pistons (voice coils) - and it is completely reasonable to suppose that these diaphragms get conditioned after so many excursions & hours of flexing and use. Anyway, after about 40 hours of listening, these phones sweetened up quite a bit.   Then I got the Byerdynamic ear pads today ($25 USD off Amazon) and...
