Quite the tumult over my Sony MDR-Z1R review. The forums churned. I think I need to re-state where I'm at.

Out on my morning web surf and I stumble onto a bombshell on the front page of Head-Fi:

"Sony MDR-Z1R Measurements: Head-Fi HQ’s compared to InnerFidelity’s"

That article links to a much more comprehensive post in the Z1R thread by Jude Mansilla, Head-Fi's Founder. It seems Jude's measurements are somewhat different than mine, particularly in terms of the peak in response around 10kHz. Here are the two plots in question.....

"I haven't heard the MDR-Z1R. BUT! Tyll's comment was that he would more preferably listen the ATH-M50Xs is hard to swallow."

Twenty five years ago when I started HeadRoom and built the first commercially available portable headphone amplifier I said to myself, "The day Sony decides to enter the fray with a portable headphone amp my mission will be complete." That happened a few years ago and I've found it quite entertaining to watch this humungous consumer electronics company try to snuggle into our tiny headphone enthusiast niche.

I feel compelled to do this about once a year...if it just save one person it's worth it. As I read my headphone news feeds it seem like I read of someone killed by walking on train tracks wearing headphones about once a week. Often it's a youngster. It seems so avoidable: Just don't walk on train tracks...period. But in a number of cases—one below—someone dashes across the tracks to catch a bus or talk to a friend and the headphones prevent hearing the oncoming train.

About a year and a half ago, SCOTTeVEST sent me a jacket to be included in the 2015 Holiday Gift Guide. I liked what I saw and included it. But for a product like this, the proof is in the wearing...the long-time wearing. I figured I'd use it for a while before giving it a real thumbs-up.

One hell of a story here. Interesting roots in a buncha places. I'm going to power through it with pics and links if you're interested in a deeper dive. Here we go!

For a variety of perfectly understandable reasons, Audeze was only able to provide one LCD-4 for measurement and evaluation. I now have 3 LCD-4s measured and have put them in this AllLCD4Measurements.pdf.

Big thanks to a headphone forum member who reached out with an offer to share his Utopia and LCD-4 for me to measure. One more for the Focal for the Utopia measurements .pdf booklet. It's A1BEHF000384 on page 10 and 11. Generally, it matches the rest of the Utopias measured with a couple small things to note. I'll reveal the LCD-4 measurements when I have enough samples for a good comparison.
