I was measuring some DIY headphones this weekend and got sucked into playing with filter paper in front of the driver. Thought all you DIYers out there would get a kick out of the data.

Grab a drink and turn on some background tunes, this is going to be one hell of a ride.

Saw this yesterday and though it absolutely tantalizing...both for its irony and potential.
To be truthful, I don't quite know what to think. Check out the video below.

(BTW, Bose already does have the QC25 in Triple Black.)

Bose by Black!?
Jack Black would sell a ton of Bose Triple Black QC25!

Yes, it's funny, but it really wouldn't work.

Sorry about that weather, East Coast.

Seems like the celebrity headphone wars of a few years ago has calmed down. On the other hand, the battle for a share of the astonishing growth in the headphone market rages on.

Winners? Losers? Water under the bridge and future promises. My comments on 2015 within.

In the midst of performing measurements for a headphone amp review last week, it appears I might have done something to let the smoke out of a few of its parts. Ugh.

So, while I await a returned product with properly smoke filled parts, I decided to finish up InnerFidelity's first pass of a Wall of Fame page for Bluetooth portable and table-top speakers. While I don't feel nearly as confident of accumulating the best-of-the-best array of speakers to test as I do of the headphone WoF pages, I'm convinced the selection has a broad enough range and competent quality to warrant its own Wall of Fame page.

I spent all day yesterday measuring the two different pads with four filters each of the Torque t402v headphone.

Some things just don't go as expected.

When I get stopped in my tracks I just need to say something.

Curiostity sometimes gets the better of me and I've got to take a good hard look at something. In this case, the Bakoon HPA-21 current source amplifier, and how it's different than a voltage amplifier.

What if Sennheiser engineers were allowed to make the best headphones they possibly could, regardless of cost?

Here's your answer.

First snow of the season today here in Montana.
The measurement lab is toasty and warm. Ahhh....

As I'm in the midst of producing what is essentially a large subjective review (an opinion piece on my experience with equipment), I wanted to offer up this video by Floyd Toole. He is a giant in the world of audio and I have the deepest respect for his work. In this video he explains the difference between opinion and science.

Personal audio was born with the Walkman introduction 36 years ago today. It was also a near death experience for an iconic American company.
