ATH-M50 prices have gone up (way up) and so the next logical choice was the ATH-M40, which was half the price. ATH-M40 has 40 mm. diaphragms unlike ATH-M50's 50 mm. Otherwise it's a fairly similar model; the accuracy is there too, although they're slightly colder (and faster).   ATH-M40 is...

Hello, what's a good, cheap amp design that uses the AD8397 as its core op-amp?

This is something concocted for tuning speakers and headphones for accurate playback. This is similar to the New South Wales' University page. But set up to match Foobar2000 & Winamp (+SuperEQ from Naoki Shibata) EQ bands.   Ideally this post would be stickied.   There're two versions...

...have rather strangely made it here. As a gift.   They look like this:       And they're - wait for this - a gaming headset built around the K-81 core. There's no mistake whatsoever, the square apertures in the driver grille and the typical K-81 "bass, low midrange, midrange, some...

SIGH. See this?       These are very seriously modded ATH-M50. With a simple fruity Touch player, G4 or G1, they challenge my monitor speaker setup on balanced wiring. Of course a fruity player is still a fruity player, running at lame 44/16. Of course it's still a lot duller than any...

...have just made their way off the flea market for the equivalent of US $15.   Initial impressions: easily the most balanced Denon headphones for electric guitar/rock/metal/etc. Resolution is lower than AH-P372, but the AH-P372 have those awful peaks in midrange that invoke a lot of crackle...

The AH-D310 are Denon's cheapest headphones in the AH-D line. Curious, isn't it? Well, they're not the elusive "AH-D1001 on a budget" (or AH-D2000, etc.). But... But. In the class of $50 headphones they're quite worth the money.   Looks like Denon (or rather, Foster) decided to jump into the...

After so much talk about the RP-HTX7 it dawned one day that they might be pretty good outdoor headphones. When modified.   So well... The modified set is sitting on the desk next to the MIDI keyboard right now, and it's already played for a few days on the street.   Stock RP-HTX7 are...

The big annoyance of MacOS had always been the lack of a player like Foobar2000. There still isn't anything like it. It lists several players that can do direct hardware access and resampling.   By the way, most new Macs have rather decent built-in Intel audio chipsets that support 24-bit...

Hisoundaudio Live Earbuds Type: dynamic, open. Driver size: 16 mm. Nominal impedance: 32 ohm. Sensitivity: 105 dB/1 mW [?]. Maximum sound pressure level, at 1 KHz sine tone, 1 VRMS: 125 dB. Frequency response: 16-22 KHz. Plug size/type: 3.5 mm. stereo miniplug (compatible with...

There have been lots of private messages about recabled Denon headphones, so here's a little guide to components and recabling. L-R: Denon DJ DN-HP500, Denon AH-P372W, AH-D1000. All headphones have a 1/8 Techflex jacket (expands to 1/4). DN-HP500 have a green/black mesh over Japanese...

Which would these be? The lower the price, the better. Efficiency has to be at least 110 dB/1 mW. The louder, the better. Supra-aural/foldable and comfortable is a plus. Most important: cups have to be disassembleable. Screwed together, not hot-sealed plastic or glued (this is for a recable).

There's a bit of a trouble with portable players. Most are built to preserve battery power, so they don't cover the whole frequency range correctly. There always are sagging harmonics. Most portable players can't make headphones play as full or accurate as, say, a notebook PC. Portable headphone...

DN-HP500 are Denon's new "junior" DJ headphones. "Junior" because of the price and size - DN-HP500 are cheapest and smallest in the Denon DJ line. The only supra-aural headphones in the DN-HP lineup, DN-HP500 are the affordable Denon DJ headphones. There's nothing "junior" about the sound...

Look like a nerfed version of K-141 with a fixed cable. K 121 Studio - Specifications Curious.

First impressions... They smoke the AKG K-81DJ/K-518DJ in every way: comfort, clarity, soundstage depth, speed, efficiency, and dynamics. Build isn't as cheap as K-81. They're slightly larger than AH-P372, are supra-aural, and comfortable. Repeat: comfortable. They're more comfortable than...

Material cost: approx. $30. John's SPC wire, sleeving, heatshrink, plugs.

Long story short, these can be the best all-around supra-aural foldable headphones recabled. Relatively cheap, small, not that difficult to recable, quick and lively, and good-looking. And, they're pretty good stock. At less than $50 off The Big Online Sales Site, they're great value. With some...

Silver-plated AWG 30 twisted pair recable (4 wires/channel), two cotton layers (backwave damping+external layer for extra isolation). There's going to be an extension (the cable is short, ~40 cm.), just like the original (stock AH-P372 have a 0.5 m. cable and a ~0.8 m. extension). So far...

First, a few words about the K-81. The Head-Fi K-81 appreciation thread made them look as if they were the "headphones for anyone", with a few comments about how they remind scaled-down, less detailed K-240 Studio. Trouble is, the K-81 are very unlike the K-240 Studio. The K-81DJ are just...

AKG K-240 Studio -> Sweetcome cable -> Cowon T2.

First of all, there have been comments on how those are bassless... Especially at the Headphonic thread. They're not bassless. They've an elevated treble and midrange. The included frequency response graph shows that. Hence, they require equalisation... The midrange and high humps can be...

So all of this - AKG Revamps Headphone Line - is pretty much the same stuff with new colours? Sure looks like it by the specs.

Two questions actually... One is - what exactly is impedance in headphones? How is it created, how is it raised, how can it be dropped? A resistor can be added to increase impedance, but how about decreasing impedance? E. g. how exactly can a set of headphones with an impedance of 600 have...

A question for canalphone owners... What can tips be cleaned with?
