A Completely Unfair First Impression of a Well-Respected Headphone Beloved by Thousands if Not Millions
The story of my K501 adventure starts where any good story these days really starts: eBay. I snagged a BIN auction for a new K501, based on the buzz here and figuring that I liked AKG's mics, so could their headphones be all that bad? Plus, the consensus seemed to be that they were "neutral", which of course to many means "boring and otherwise lacking in hormonal excitement". Perfect for me as a post-hormonal, mature (ahem) sort of person who's had enough excitement in his life, thank you very much. I value smoothness and effortlessness in both headphones and pro tennis players, so the K501 became a designated wallet-target. Ho hum, another uneventful eBay purchase.
Until the auction blew up. The day after I snail-mailed the check, eBay emailed me to say there was a copyright owner objection to the sale and that it should never have happened-- and to demonstrate their awesome Orwellian power to erase history they wiped all traces of the transaction off eBay's shining face. Poof. Never happened. I was on my own. Fortunately the seller was on the up and up, and today, 30 days after I mailed the check, the K501 arrived.
Keeping in mind that this K501 is still green and oozing sap, imagine my surprise when, despite warnings by many Head-Fiers that the K501 has "weak" bass, I saddled up my new purchase with my superduper Realistic STA-2200 Headphone ReAnimator receiver [see my earlier post on this bit of vintage gear and what it did for the HD-600] only to find that the bass wasn't weak at all.
Perception of bass has a lot to do with how well the diaphragm of a transducer is damped. Underdamped bass (say, in a cheap subwoofer with its typically poorly-tuned port) is bass that sounds loud all the time-- pleasing for the first 10 seconds or so; then it starts to get on your nerves. A designer of a headphone is always trying to balance fundamental resonant frequency, bass damping and treble extension. Overdamp the bass and you gain detail but you lose that warm chocolatey sound so many crave and you perforce raise the effective stiffness of the diaphragm's suspension, which moves the resonant frequency of the diaphragm up into the midrange which makes the bass seem weaker still, and bla bla bla. Underdamp the bass and you win friends and influence people. Hormones never go out of style.
I figured, based on the posts here by owners and ex-owners, that the K501 made the tradeoff in the direction of more-detailed bass (the old quality over quantity gambit) compared to the Sennheiser HD-600, and that, as with any overdamped diaphragm, some good old bass EQ would bring up the low end and all the glorious detail and impact that is the reward of making this tradeoff. So imagine the flat midrange and nice smooth extended treble I was hearing. Imagine my smile as I turned up the deep bass on the STA-2200's tone controls.
Hah. There was no "weak" bass. There was no bass. None. Dropped like a rock. Never happened.
I practically laughed out loud. After the positively smacktile bass of the Yamaha YH-100 and Fostex T-30 and the very respectable bass (even without the EQ crutch) of the refurb HD-600s, this was indeed an excellent joke.
Not that I don't like the K501. Just the opposite.
This particular K501 is, as I said, brand new and will probably change with time, though with some 'phones it's painfully obvious when they have a long way to go basswise (I think of the Fostex T50RP-- gerG will know what I mean). Meanwhile, I'm enjoying the K501's essentially flat response (far flatter than the T50RP) and effortless high end. At this point they're like expensive minimonitor speakers. No bass but everything else is just right.
Updates as they happen.
