Most retailers around the globe have the option to stock spare parts if they want. Some do, some don't. If you like to buy through them (and we think that's great) ask them if they can procure it first. But you be able to buy them though the sennheiser-hearing.com store/office after launch. The...

Thank you for your feedback but we feel this this headphone is terrific, and its just about ready to ship (first week of June). We hope you get to try it, and if you don't like it that's fine, it's your opinion. We've already explained why the 500 series is the ideal chassis/enclosure and it's...

Correct. 500 series pads (velour) will fit but alter the experience of listening dramatically to where I would not recommend it. The HD 620S pads will be sold separately, however 👍

Thank you! @Jermo K and his team mare doing a great job. We're excited for you to hear it. Nothing against the HD 558 but the HD 620S will be a massive upgrade, closed-back or not. Thanks for the trip down memory lane. That was a gateway headphone for so many of us! They already are...you can...

No IE 300?!?!?! WHAT GIVES?! hahaha kidding kidding 😁 You rock 🤘 Any favorites from your whole collection?

It's actually wider than many, many open headphones I've heard.

It's not possible for one headphone to accommodate all personal preferences, but we are pretty confident that we are filling a decent sized hole in the market with it's tuning and presentation. Hope you get to hear them with your own gear and ears 👍

The padding has an adhesive but will still be replaceable. Based on the material spec it should last a long time. You will be able to buy a spare parts for it. The HD 620S is indeed more brilliant in the treble, that I think many will describe as "clean" as it lacks sibilance but still has bite...

Thank you so much! Based on what you describe I think you are in for a treat.

I think you know the answer 😁 haha But seriously, thanks for being an awesome customer. That's a great collection!!! I can confidently say that the HD 620S has a unique tuning among all of the cans you just listed so there is almost zero redundancy from an overall signature perspective. Of...

Here's a few stills pulled from the video tour I'm working on...

The great @Ichos surfaces in the wild, capturing his prey with deft efficiency. Glad you got to hear them!

I might have to pull the trigger on one of these. I need another thumbDAC like a submarine needs a balcony but this is Head-Fi so ...

Indeed, swapping the stock pads for velour pads add zero acoustic benefit and drastically alter both bass response, focus, and soundstage. We'll pass the boom mic feedback along. We already have an in-line mic option for the 500 series that works with the HD 620S. Headband padding is...

Hope you get to try it soon like this head-fier 👇👇 Now I'm going to try my HD 598 pads on the HD 620S because why not? Edit: don't bother

If this were any other ordinary Thursday, I'd mount it to my KU 100 and give you a video demo, but I'm in the middle of a move so it's in storage. I believe we have isolation specifications for the wearer, but not the other way around. That said, I can do a down n' dirty practical demonstration...

measurable quantity and perception are definitely on separate-but-perpendicular rails.

When you get to the bass curves, it starts to get subjective as we're talking flavor and quantity. I do believe most listeners will find the HD 660S2 signature to be warmer and more relaxed overall, and that bass breathes really well. I do believe most HD 620S listeners will find its bass to be...

Lol! A custom erics75 edition? Deal! The metal reinforced headband makes a big difference. It keeps everything anchored to the core really, really well. I was doing some measurements/comparisons with my old 598 yesterday and the 620S feels as solid as anything we've done yet. The 598 is...

We appreciate the excitement however this review broke our embargo, as we put in almost one month of review time, knowing that the audience here needs more than an unboxing and quick impressions video. They did not obtain the unit from us. Behind the scenes we are working with some familiar...

Big day for new product launches. Don't forget new iPads, Pixel phones, portable speakers, etc etc

The stereo presentation is different as well. Much, much wider....especially for instruments. If you love hearing what the mix engineer did to make the stereo mix interesting, this is THE closed can for it. Correct.

I might not have been clear, sorry: the HD 620S is ready for balanced. The balanced cable is what will be offered in the summer.

It's wired for balanced and we'll have a factory balanced option this summer. Yikes!

Indeed I'll let @Jermo K comment on that as he is much closer to the transducer philosophy. Historically, many of our aluminum voice coil drivers have lower impedances (than 300 ohms) and I presume that to get to the 300 ohm load, you'd need much more aluminum, and that would negate the...
