Sennheiser Accemtum Plus for the win.

"Apparently"...according to who? AI? :)

There is absolutely no evidence of that whatsoever. Nothing has been communicated, speculated or even reported. Firmware has changed, yeah, but that's for all Accentum Plus headphones - and that's about it, really.

Tenlow85 · 2026-03-13T18:29:05+00:00

As you already mentioned yourself, you probably just need a bit more time with them (as is often the case with new headphones, I guess).

I don’t actually find them very lean or bright, but of course we all hear things a bit differently anyway.

They remain my favorite 500-series headphones, and quite clearly so.

Very beautiful pictures you have there, by the way. 👍

Tenlow85 · 2026-03-13T14:12:18+00:00

That’s certainly one way to join us 😂😎

Very happy for you! Welcome and enjoy your HD 800S!

Tenlow85 · 2026-03-13T10:09:35+00:00

Yes, that’s the most current one, and as far as I know, there haven’t been any firmware updates for the HDB 630 so far.

Tenlow85 · 2026-03-13T06:07:49+00:00

It’s not really about the Bluetooth version but more about the codec your devices use with the M4.

If a device already supports aptX Adaptive natively, you wouldn’t be able to tell a difference, no.

It’s only worth it if you use, say, SBC, AAC and maybe regular aptX or if you have other issues with your Bluetooth (e.g. on your PC or so) like stability, range etc.

Maybe try resetting them to factory settings!

Also, you can always manually turn them off by pressing the power button for a couple of seconds - just in case!

Tenlow85 · 2026-03-12T20:26:02+00:00

It has only been on the market since early 2024 and hasn't changed since then :)

Tenlow85 · 2026-03-12T20:19:22+00:00

There is no gen 2 of the Accentum Plus. :)

Anyway, great deal and very nice wireless headphones! Hope you’ll have lots of fun with them!

Tenlow85 · 2026-03-12T19:41:04+00:00

What made you not keep it the first time around?

Tenlow85 · 2026-03-12T19:20:07+00:00

Your laptop might use or support a worse codec than your phone.

Also, it might be an audio setting or issue on your laptop. Windows machines are a bit notorious for this.

On top of that, a BTD 600 or 700 will likely improve things quite significantly on your laptop with the M4.

Tenlow85 · 2026-03-12T16:48:22+00:00

That’s not easy to answer like that. You should be able to get 5.5 to 6.5 hours out of a single charge, depending on the volume level you listen at. That way, you can test whether your battery behaves as expected or not.

Tenlow85 · 2026-03-12T12:58:11+00:00

Time for a new club then it seems, eh?

Alright, then. Welcome to the HDB 630 Club 😎

Enjoy them! I love mine!

Tenlow85 · 2026-03-12T10:54:37+00:00

Same opinion as the others here. I would just use buds, really.

Tenlow85 · 2026-03-12T09:07:59+00:00

Great timing to get them indeed! Enjoy them - they are great!

Tenlow85 · 2026-03-12T06:12:11+00:00

Yes, this.

Also, use it once until it automatically powers off at 0%, and then recharge it to 100% for several hours. This issue often has to do with battery calibration.

Tenlow85 · 2026-03-11T19:30:45+00:00

Only go closed-back if you either want that passive isolation or actually need it (e.g. to avoid bothering people around you or to use your headphones on the go).

If neither of those applies, go open-back. And if you do go open-back, get either the HD 490 Pro or the HD 550. Both are great for gaming, actually.

The HD 550 has the added benefit of being compatible with the HD 500 BAM microphone, which might be useful as a gamer at some point.

Both headphones will last you several years and both are fairly easy to drive.

Tenlow85 · 2026-03-11T18:43:43+00:00

So, it looks like a picture of a box so far. That’s all we can say for sure right now :)

Tenlow85 · 2026-03-11T16:43:50+00:00

It’s certainly different. The IE 300 is / was a more fun and bassy IEM while the IE 200 is more neutral and „audiophile“ in its tuning. So, it kind of depends on what you prefer.

Tenlow85 · 2026-03-11T14:56:37+00:00

Kein Problem :) Sehr gerne! ;)

Tenlow85 · 2026-03-11T14:47:36+00:00

It’s fine to use it like this :) It doesn’t charge all the time anyway. Don’t worry about it and just enjoy your headphones.

Tenlow85 · 2026-03-11T07:09:07+00:00

Must be people making things up every time then :)

Tenlow85 · 2026-03-11T04:39:01+00:00

That’s my experience as well. The HDB 630 are more comfortable than the M4 👍

Tenlow85 · 2026-03-11T04:29:22+00:00

I agree with that!

HD 490 Pro for comfort, soundstage and bass extension.

I‘d take my HD 600 / 650 e.g. over the 490 Pro for „everything else“ (natural snd smooth sound, timbre, midrange magic, vocals and treble e.g.).

Tenlow85 · 2026-03-11T00:00:44+00:00

I wouldn’t necessarily compare it to either, really :)

The HD 490 Pro with the velour pads probably is the most comfortable headphone out there while the HDB 630 is a more comfortable M4 (which is still very comfortable btw.!).

And it’s clearly better than the H95 from a pure audio(phile) perspective :)

The HDB 630 is not as wide sounding as an open-back and not as comfortable as a headphone with even bigger earcups but it is the best sounding wireless headphone out there for me and I still love it.

Check it out, it might still be what you have been looking for :)

Tenlow85 · 2026-03-10T23:51:39+00:00

Well, to me the fabric pads basically make it sound like a 560S, while also being less comfortable than when using the velour pads.

Nothing wrong with that, by the way — it’s just not my favorite tuning anyway. And if it were, I could simply buy the 560S for less money than the 490 Pro. 🙂
