I believe myself to be a closet audiophile being hampered only by my lack of funds and, as of the last few years, time. I can thank Shawn Heisey for introducing me to the wonders (and pleasures) of audiophilia — much of my teenage years was dedicated to the pursuit and with modest success.
I’ve always been an early adopter of audio technology as well. I have the first walkman sony made that ran off 1 AA battery and I have the finest walkman AIWA ever made. I’ve got one of the first portable CD players made by DAK. I have a Diamond RIO MP3 player (the first comercially produced MP3 player ever) and the Archos 6000 Jukebox (the first hard-drive based MP3 player). I’ve made speakers out of toiler paper mache and rolled my own cross-over filters. Humm, this is sounding like another post — but I digress.
But with all of them you need headphones for portable sound, and I have a small collection of them. Initially, I wanted to talk about my quest of comfortable wide-frequency headphones and some of what I’ve found. But now it’s turned to something else that is long and unwieldly. The short version is this: Buy some Apple In-Ear Headphones — you will love them.
AIWA HP-D9
The famous HP-D9 was manufactured between 1991-1994 and was AIWA’s top-of-the-line bud earphones. It has a 60 millimeter U-shaped bass reflex channel that can reproduce signals as low as 5 HZ and as high as 30 KHZ. It sports a unique 4U thin noncrystal linear voice coil wrapped by oxygen-free copper that continues into the flexible cord. The 24k gold-plating stereo sound attachment includes a threaded neck whereon a larger adapter can be fastened and screwed on for secure attachment. The impedance of 16 ohms makes the volume feel like 108DB/ milliwatt. It weighs only 9 grams.
In terms of pure technical excellence in bud earphones, these are some of the best ever made — and you can hear the difference. One small problem: my ears are a non standard size/shape which prevents the headphones from sitting comfortably in my ear and, more importantly, creating a pratical seal with my ear canal so those 20 HZ frequencies make it in. Unfortunately, I find them uncomfortable and not that great… stupid ears.
Apple In-Ear Headphones
These headphones actually sit in the ear canal comfortably and while they block outside noice, they deliver all the bass and crispness of trebble generated by the driver. These are nice headphones and since they sit directly in the ear canal, they function
They aren’t as good as the Etymotic Research ER-6 headphones, but who has $139 to spend on headphones (I suppose real audiophiles do).
Although I can’t find technical specs for these headphones that would reveal their frequency range I did run my frequency test and found they worked great from 30 HZ to 16 kHz (which is as high as I can hear). Frequencies as low as 20 HZ were reproduced, but not at a weaker volume. There is a rather good review at MacMerc.com. I would concur with the reviewers findings and found the $39.95 price tag high (eBaY has them for around $20) but still less than Sony models of the same variety — plus they will look great with my iPod that I’ll someday get.
Radio Shack Optimus LV-20
The wonderful thing about Radio Shack is that they rarely make their own stuff. Take, for example, the Optimus LV-20 headphones which Radio Shack sold me for $22.00. These headphones are really made by Koss and it even has the name Koss molded into the headphone jack overmolding. So for $22.00 I really got a $60 pair of headphones which are most equivellant to the Koss TD-80.
With frequency response from 20-17,000 Hz and including a 10 foot cord with volume control, these headphones are my favorite for comfort and sound quality.
The only problem with these headphones is that they are not really portable. Sure I see kids on the street all the time rocking out to their hip tunes wearing large headphones — but although it may be the fashion of our time it is not the fashion of my time and we all know we get locked into our high school decade. I just can’t bring myself to walk around with an MP3 player the size of a chapstick tube and wear headphones where the plug adapter is the same size as the player itself.
Nevertheless, these are my favorite headphones.
