Steve Guttenberg, Tyll Hertsens • Apr 25, 2012 • 42 comments

I talk with Steve Guttenberg on the phone a few times a month, and I very much enjoy our chats. When Steve suggested we have a conversation about measurements and their relevance to audiophiles and write it up as an article, I was all-in immediately.

I hope you enjoy our chat as much as I did.

Tap your cheek bones, and you'll hear it plain as day. The sound's not coming through your ear canals ... it's just rattling the bones in your ear, and you can hear it. But is this a good way to get your tunes?

Tet, as he likes to be called, wanted to see me put his latest creation, the Hesh 2 (~$50), through the ringer. Sure! Just as long as I get to pick you brain on headphone measurements. We ended up talking a lot about a wide variety of all things headphone, and we both learned quite a bit.

A hard-core headphone mini-meet, indeed!

Like most people upon first hearing the Audez'e LCD-3 at last year's CanJam at RMAF, I was struck by the quicker sound of the new planar magnetic headphone over its predecessor, the LCD-2 Rev. 2. Definitely a step in the right direction. Then they started shipping ...

When my daughter and I make pizza, we have a little routine of listening to music on MOG and alternating our picks --- neither of us can take the other's music continuously. But when I played "Pump Up The Jam" by The Lost Fingers, she wanted to hear the entire "Lost in the 80s" album.

The Lost Fingers are now a recurring presence during our culinary adventures.

I really wanted to objectively show break-in effects were measurable and audible.

"Desire," says the Buddha, "is the source of our suffering."

Guess I'm not going to get what I want, I'll just have to stop wanting it.

Wanna see what I did get?

Steve Guttenberg • Jan 06, 2012 • 4 comments
Steve Guttenberg and I had an interesting talk abut how we use headphones for movie and TV watching a little while ago. Quite a few nooks and crannies in this somewhat underserved area of headphone listening. He thought it would be a worthwhile write-up.

Let's have a look at Steve's thoughts ... I've added some of my own at the end of his piece.
