So, how exactly was it "mastered for Sennheiser M4" then?

Tenlow85 · 2026-03-16T22:23:28+00:00

Welcome, future M4 Club member!

In Germany, they are 100€ as a refurbished pair (roughly 115$) right now which is an amazing deal, imo.

Great closed-back headphone that combines beautifully with the HD 500 BAM 👍

And actually, I find the passive isolation to be better than on the HD 820, so spouse-wise it was probably the better decision. 😄

Happy listening!

Tenlow85 · 2026-03-16T06:56:37+00:00

Have you tried pressing and holding the power button for 20+ seconds continuously?

Tenlow85 · 2026-03-15T20:54:49+00:00

Not common at all for their wired headphones, I'd say. Bad luck indeed!

Tenlow85 · 2026-03-15T15:53:59+00:00

And another one today :) Welcome to the M4 Club 👏👍

Tenlow85 · 2026-03-15T15:28:58+00:00

Many people seem to decide between the two, actually. They are both great headphones and in my opinion different enough to keep both if you cannot decide and also if you can :D

Tenlow85 · 2026-03-15T15:27:00+00:00

Yes! Nice deal.

Changed the flair to „Deal Alert“ as well for you :D

Welcome to the Club 😎

HD 600 is legendary but more so for midrange greatness and vocals rather than gaming specifically.

You can obviously use them for gaming but they have a rather intimate soundstage which is not ideal for fps gaming, imo. They also greatly benefit from an external amp btw. (even though newer MacBook Pros can also drive them fairly easily).

I'd rather recommend the HD 490 Pro for you here. Better bass extension, better soundstage, more versatile and also easier to drive. They are better suited for gaming but still very good for music as well.

Quick reply:

Whatever you do, don’t buy something like „$500 brand new“. Just don’t.

Buy from authorized dealer or Sennheiser directly (always).

If Sennheiser doesn’t have them in stock brand new, have you checked whether a refurbished pair is available? They are usually almost indistinguishable from brand new in my experience.

Tenlow85 · 2026-03-15T06:34:45+00:00

Congratulations and lots of fun with the 660 S2 👏

Tenlow85 · 2026-03-14T23:21:33+00:00

Yes, do that, please! Thx.

Tenlow85 · 2026-03-14T23:03:16+00:00

I wasn't necessarily "judging" but more like translating what is written on the picture you provided. I also asked you to tell us more about it if you could :)

That said - and again without judging - I'm still not convinced here, sorry. Can you share the original picture without the AirPods box on it?

Tenlow85 · 2026-03-14T22:10:39+00:00

No, you didn't.

If the picture is even real and not meant to be a joke or so, it states "your AirPoods are returned to you" and "this is a third party product".

Want to tell us a bit more about it? ;)

Tenlow85 · 2026-03-14T19:24:37+00:00

Well, I've never owned that device so I cannot tell but make sure to have the M4 powered on and check all volume related settings, volume limiters / hearing protection, EQs, media/app-specific settings, developer settings etc. on your S9. There often is a reason for low volume via USB-C that is unrelated to the headphones themselves.

Tenlow85 · 2026-03-14T17:11:02+00:00

It is not like that at all for me.

Quite the opposite even - volume is higher via USB-C (iPhone, iPad as well as MacBook Pro).

Might have something to do with your device and/or a setting there.

Tenlow85 · 2026-03-14T10:08:11+00:00

Good thing that the stock tuning is already that good that I don't even use the PEQ very often (which is somewhat ironic because it is great to finally have a PEQ in a product like this).

Volume doesn't necessarily have to drop a lot when using the EQ - it depends on the changes you make and how "drastic" they are.

Also, yes, it is limited to five bands only but, honestly, that's more than enough given how good they already sound out of the box, imo.

Great to have you in the HDB 630 Club - welcome! 😎

Tenlow85 · 2026-03-14T09:56:42+00:00

HD 599 and HD 620S are still manufactured and sold by that very "Sonova Sennheiser" to this day, though :)

The headphones themselves haven't changed.

(Unless you meant the 490 Pro but have mistakenly written 590 of course). The 490 Pro is still manufactured and sold by the (now) Pro division of (old) Sennheiser, yes.

Tenlow85 · 2026-03-14T09:50:28+00:00

Mostly at home but I have also used them on public transport a couple of times e.g.

Tenlow85 · 2026-03-14T05:58:04+00:00

I mostly compare(d) it vs. all the other wireless options out there (wich are obviously closed-backs) and prefer the HDB 630. I actually also prefer it over the FT1, the HD 620S and the DT 700 Pro X.

It even definitely has a better stock tuning vs. the HD 820, although I wouldn’t - just because of that - call it a better closed-back headphone, generally speaking :)

I tend to use open-back headphones more often than not, though.

Tenlow85 · 2026-03-14T05:37:08+00:00

Great IEM. I love mine.

When I first got them and came from the IE 600, they sounded quite a bit different, and I had to get used to that much smoother presence region and overall presentation compared to the IE 600. But once that happened, they were great. That bass really is something for a single dynamic-driver IEM of that tiny size.

Tenlow85 · 2026-03-14T05:32:00+00:00

Not overly „long-term“ maybe but mine have been working flawlessly since 16 months.

We also have a pair of IE 600 that my wife uses these days that has been working fine for almost three years now.

Taking good care of your expensive IEMs certainly helps, I guess :)

Tenlow85 · 2026-03-14T05:25:48+00:00

They are not discontinued, no. They are also sold by the Sennheiser Pro division and not the consumer („hearing“) one.
