This Week in Headphoolia #10: Sennheiser HD820 leaks (up to 4/30/17)

Time sure does fly faster and faster. Another week is gone, so here’s another round-up. I promise I will have more content in-between the round-ups… one of these days 🙂 Theme music while preparing this round-up: Kraftwerk’s “Trans Europe Express” album, FLAC (rip from CD), with the Philips SHP-9500S (review is coming, just like the “Winds of Winter” is coming; unboxing already posted) through the Fiio X1 DAP.

These round-ups are intended to be a fun/funny round-up of the action, but they are not intended to be comprehensive. I can’t post every review, every new headphone announcement, every news item. That’s a full time job ~ please feel free to load up the Patreon if you want that 🙂


Sennheiser has unleashed a boatload of HD 5XX and HD 4XX headphones, they even teased with a special edition of the HD 6XX series at Massdrop, but it looks like they are not done. A leak spotted the mention of a Sennheiser HD 820 headphone in marketing material.

This is discussed with varying degrees of excitement in the various forums, such as Super/Best/Audio/Friends and the Rule 9 forum and a little bit at Sponsor Fi. Meanwhile DMS3 TV (video) crackpot-theorizes this might be a closed back headphone (Sennheiser already has two open models in the HD 8XX series after all).

This should not be confused with a new “real” product from Sennheiser that got ushered out, the HDV 820 headphone amplifier which got a four minute preview at HeadFI TV (video).


Headroom is going back to their roots again, they announced earlier in the week they are getting out of the retail business and going back to producing amps and headphones. Their planar magnetic has a summer 2017 release estimate. They also have their prized domain ( up for sale, bidding starts at $100,000 at the moment.

The domain name should not be confused with the plural which is owned by two brothers in Portlandia that sell headphones too.


Another long post about the CanJAM 2017 (SoCal show) got posted at Headphone Guru after I finished last week’s round-up. This is a very well done report, with a good mix of pictures and text, and no autoplay audio/video. A great read to sneak in while taking a self-determined break at work 🙂

If you are interested in AXPONA, there’s more action at Stereophile. This is not headphone centric, but audio-centric.


Metal571 is back, this time with a new 24-minute educational video on equalizing headphones, more specifically with EqualizerAPO with the Peace GUI. YouTube embedded below, relevant links and example equalization file in the YouTube video description box over there…

MQA? That is so 32 Kbps mp3! All the cool kids are doing Multichannel MQA now 🙂 Joking aside, here’s a four page article on Multichannel MQA at Stereophile.


It’s an earphone-heavy week, with all kinds of IEMs reviewed, from three figures to four figures 🙂 But first, some action on the … Windows 10 front. The Creators Update is bricking systems rolling out as we speak, and @Archimago posted a detailed evaluation (with lots of charts and graphs) of the USB Audio Class 2 Driver (that comes with Windoze).
