The day had to come...

For many years now, and as some of you may have noticed by now, I’ve been a passionate Sennheiser afficionado and despite the now rather large collection (and all the other headphones I’ve owned throughout the years), the HD 800S had always remained that one missing piece - the missing puzzle piece, really - until today!

Yes, I even ended up getting the HD 820 before the HD 800S somehow :D

Of course, I had already listened to the HD 800S multiple times throughout my life, but I had never actually owned one myself until now.

My late father once had a very early “Made in Germany” unit some years ago, but unfortunately sold it at some point - but that’s a different story of course.

What matters much more is this: the collection has now finally been expanded by a lovely brand-new HD 800S. Attached are also a couple of visual impressions.

Just wanted to share that quickly - and that’s pretty much it already (for now at least) :)

Curiosity got the better of me, so I picked up the still fairly new HD 400U headphones as well as the CX 80U earbuds today.

Both are the new “digital interface” USB-C versions of the existing HD 400S and CX 80S, and I figured - since plenty of people are looking for easy-to-use, budget Sennheiser options for their mobile devices - I might as well check them out for the community here.

I’ve also uploaded 18 pictures of both devices in case you want to take a closer look of the products and the unboxing experience.

I’m sitting down as I type this, listening to the HD 400U for the first time, connected to my iPhone 17 Pro Max.

Proper impressions will follow later, but feel free to already ask anything you’d like to know if you’re interested in either the HD 400U and/or the CX 80U!

A couple of quick key specs and first "impressions":

- Both offer 24-bit / 96 kHz audio playback via the USB-C connection.

- Plug and play - that's it. No app, no ANC, no batteries.

- There's a one button remote control with an included microphone built into the cable for play/pause, next/previous track, answer/end calls and quick access to digital assistants.

- Practically works with any modern mobile phone, tablet, handheld game console, or PC/Mac.

- The HD 400U comes with a really nice and quite good qualiy pouch for storage and the headphone folds nicely into a very compact form factor.

- The cable on the HD 400U is actually detachable!

- CX 80U are absolutely tiny and weigh next to nothing + they come with three different sizes of silicone eartips.

- MSRP prices: HD 400U: 79.90€ and CX 80U: 39.90€
