Sennheiser HDB 630

In my experience Li-Ion batteries manufactured in Japan and S Korea will last for a very long time, even when not treated well.
Batteries from China are a crap shoot ranging from pretty good to absolute garbage.
Samsung, Panasonic and Sony are the best that I know of. I have well-used 18650 cells that are over 9 years old and still perform almost as good as new.
Obviously you don't always have access to who manufactured the batteries for the device you are contemplating buying, but it never hurts to ask
 
I picked up a pair of these a couple weeks ago. The bad news is I don't think they're going to make my work travel kit -- case is just too thick. Hard to squeeze in a briefcase with all the other tech crap one finds oneself needing. Also don't make the mistake of looking at yourself in the mirror wearing them. The way the side arms are shaped with that outward kink and the silver plastic is just unattractive IMO. Maybe they'd look better if the side arms and gimbals were blacked out.

The good news is they sound really good. Tonality seems basically right out of the box, and the processing suite included is basically ideal: PEQ as well as crossfeed may as well be designed by (or "borrowed" from) RME it works so well to round out the sonic presentation when set to "low." Even so, it's not quite as wide sounding on my head as AKG N700NC M2.
 
just bought these headphones a few weeks ago and never even gave a thought to battery life.
i may end up regretting it.
sonically i find them far better than the only other 2 anc headsets that i have tried, being the PX8s2 and original Bathys.
its ironic that the main reason i chose the 630's was the fact that the eq profile could be stored in the headset, yet i have not fealt the need to use eq as yet.
 
Setting aside for a moment the fact that my smartphone gives me all the data explicitly, and we agree that it might not be fully reliable, there are affordable devices (<€100) like USB meters and good-quality multimeters, all the way up to more advanced equipment like the Yokogawa WT300. Sure, these aren’t the kind of instruments you’d find at SpaceX, but as you can see, you can manage just fine without spending a fortune.

Anyway, I don’t have to justify anything and I don’t see why I should, but you’re the one implying that a battery that’s gone through just a few dozen cycles is already fit for the trash. That’s absurd even to consider.

And no, I never told you that after 8 years a Sennheiser would be worthless, only that realistically you might be around 80% capacity, which would still be excellent. Even at 50% you’d still have better battery life than brand-new AirPods Max, so you’re imagining a world of problems that simply doesn’t exist. In the worst-case scenario, a lithium battery typically has a potential of around 300 charge cycles before dropping to 80%.

Then again, you’re free to believe that in two years the HDB630 will have batteries ready for the bin, if that makes you feel better

Out of curiosity, i googled about modern Sennheiser wireless headphones and batteries.
The Momentum 2.0 batteries released in 2019 are now U/S and there is a cottage industry (see reddit) in providing 3rd party replacements.
That's 6 years and doesn't seem surprising to me.

Sennheiser themselves have had to reengineer the earbud beattery designs and change manufacturer of the in-ear 3,4 series as acknowledged publicily.

For a set of earphones this expensive, the manufacturer should be providing support and repair options for them.
Telling the consumer that the batteries are not replacable and telling you to bin the headphones when done ( EU End of life protocol) is not workable imho and i would expect more from them tbh.

More fool me eh.
 
i wish i could find a wired closed back with decent passive isolation and same fr as the 630 (out of the box).
dont think one exists
The AKG K371 and FiiO FT1 are the two wired headphones in rtings' database which come closest to the 630's fr and also have decent noise isolation.

But they have like 3dB more bass.

The aptx does not work with most samsung phones.
The provided dongle is a bit cumbersome ass all dongles one phones are.
Dongles are easy to get lost.
Why did they not include LDAC.

I'm debating buying this, can you replace the battery that WILL fail in 5 years or so?

No.

Well, you could somehow get into it and put in something similar from a 3rd party yourself but Senn specifically state (in corperate mumbo jumbo) that the battery is not exchangable. I lokked but couldn't see any service info either.

However, in 5 years time, when the batteries are failing, i'm sure there will be knock off of varying quality available.

AKG K371, I'm wearing one at work right now. It does not have ANC so I don't think it works as well for 630 blocking sound but if I play music/YouTube and wear these headphones it drowns out coworkers.
 
So the question of sustainability and maintenance of this headphone has just gone up (or down) a notch with the news that the company that bought the company who makes them, now are reselling said company. Again.

Who or what is going to own Sennheiser next? What happens next?
 
It's hard to believe that the parent company decided to sell the Sennheiser consumer division right after they released such a universally praised product. They must've had unrealistic expectations for sales, it's the only thing I can think of other than possible corporate plundering ie, patents, ip and such.

Have you tried the Sennheiser HD620S? I find its isolation to be rather good and its tuning shouldn't be too far from the HDB630's default one.

Looks decent with some help from EQ, but without EQ the huge peak at ~115Hz will break that association:

Hey all, I’m in a pickle, and I hope you can help me.

Somehow, HDB 630 turned out to be the best and most natural-sounding of all the headphones I owned or tried. The timbre is unmatched; most music instruments sound just right and life-like. I want to attribute this to good sub-bass and filled mids, but maybe it’s because of DSP witchery and closed-back construction. I’d love to try/buy another headphone like HDB 630, but a open-back construction that carries a similar timbre/impact. I’d appreciate hearing from anybody who has a similar experience to mine and has heard another headphone with this life-like quality.

Seems like a good price for BT with great tonality and peq and a more luxury build quality. I'm not really sure what you guys expect the price to be, or why. Just seems like you guys are broke

Buy one and send it to Amir for measurements.
 
I'm not a headphone guy but use my Galaxy earbuds for working around the house, walking the dog, and going to the gym. How are these for working out? Not dynamic aerobics -- just lifting weights and using machines? My Galaxy buds struggle to block out the crappy, loud gym music. Will I look like a tool at the gym?
