Sennheiser HDB 630

Anyone else noticing weird compression in Adaptive with included dongle? Switching between BT from my phone and the dongle sounds completely different.

No. It sound the same to me. Not really surprising since AAC is probably transparent enough. The real issue with the dongle is still that you either use the dongle or you dont use it for 2 devices. It is not possible to mix usage with and without dongle. For me it just renders it not usable.

Interesting, I'm between aptx hd and adaptive from phone bt to dongle.
 
Can you just switch on the fly between dongle and non dongle? Like go from ipad with dinge to iphone without?

Right now I am having issues again. The headphones are connected and play music. However the app does not connect. Just wanted to dial in some PEQ. Not possible. That is so annoying.

ANC seems also bugged. On or off has no effect. Only when I switch the ant wind off I get some noise reduction.

Sennheiser really needs to work on their software.

That's not correct. On the app's main page, there is a connection management feature where you can activate Multipont, and both devices (the currently connected phone and dongle) are displayed there. It works pretty much flawlessly, just tested it with my MacBook (Dongle) and iPhone. I mean, it's not as convenient as AirPods, but it works. I've also tested it successfully with my Lenovo in the office.

Make sure the slider is on the left indicating ANC 100%. If the slider is in the middle, toggling between off and user defined shows no effect.

There is always room for improvement, but among all the companion apps for headphones, it's one of the better. However, I must admit that I spent some time figuring out how to disable the auto-pause function when turning on transparency.

I didn't realize it has crossfeed too, that's very appealing IMO. but we're still talking about the HDB630 and not the cloud X, right?

The Sony headphones have EQ but only graphic which I find not super useful.

To me crossfeed makes the stereo image seem more continuous and realistic rather than hard panned or straight in the middle. Very small trade-off in tonality. I use it in my desktop setup, too.

I think latency is overrated as a problem for BT headphones unless you know you're really sensitive to it, or you intend to record with them. Lip sync problems don't always become obvious until 200ms+ ... If you're just on a plane or train watching a movie, it should be fine.

When I mentioned crossfeed, yes I was talking about the HDB 630.

Im a bit new to EQ headphones to be honest - the mental barriers to achieving it didnt feel like they matched how I tend to listen (running audio apps on my laptop always seems a hassle, I don't like being tethered to a desktop DAC/amp with EQ etc etc) .. that is until about last week when I discovered Wavelet for my phone which got the ball rolling and then, on the basis of this thread, actually bothered to use the EQ on my Sony WH1000XM5s..

I took an AutoEQ PEQ profile and did a very rough implementation of that with the Sony graphic EQ .. and I think it does actually make them sound a lot better ... or is it just "different" ?

Anyway, I hadn't previously realised it was stored in the headphones.

I may have to set up a profile for the Sonys in Wavelet to compare, and then check if the app has crossfeed..

All of which, depending on listening habits, could make such features in the HDB 630 not needed as much after which it all then comes down to designed-in sound quality (drivers, housing etc), ANC and all that .

Blah blah .. I feel I'm waffling ! Lol

I found the reason why ANC did not really work. The wear detection did not work unless I pushed the right earcup on my head. It was follows by a clicking sound and now ANC works very good. The wearing detection is a bit tricky since the headphone works even when not triggered so I did not know something was wrong initially. I only found out it did not trigger by accident while tinkering with ANC. You can also find many threads on reddit about the Momentum 4 having the same issue with some ears.
 
He said "vast majority". I dont see anything wrong with that.

He said:

"I would take this over most of the high-end closed back, ya know, $1,000+ audiophile wired headphones"

Quantifying it as "only" most high-end closed backs at or above $1,000 does nothing to allay previously stated issues.

We have a claim that a $180 pair of headphones is better than the most of the high end headphones in the $1,000+ range with zero detail or comparisons provided to those headphones.

I don't understand your angle here, are you saying it's fine for reviewers to make crazy bold claims and then provide nothing to back them up?
 
why are we still waffling on about a different product on the Senny product page? What is it with ASR and every thread devolving into this bottomless argument scenarios

I see nothing wrong here. Most +1000$ closed backs are crap. No surprise that a cheaper on where you have DSP and someone actually cared a bit about a remotely good tuning is not surprising. The FiiO FT1 also als better that most of the +1000$ high end headphones. His claim may be bold but he has a point and it is far from crazy.
 
It’s very frustrating that every YouTube review I’ve seen of this headphone seem to claim or at least heavily implicy that these headphones do lossless audio over Bluetooth (aptX lossless) - presumably because the DONGLE supports it but the headphones don’t. Same with the AptX low latency mode.

It’s a bit dissapointing - I know you probably couldn’t tell, but it’s a little unsatisfactory that the headphones don’t support all the features of the included dongle.

I do have a real problem with Sennheiser’s marketing team being very active and commenting on many of these videos - without pointing out the mistakes. That feels like misleading marketing to me.

I almost bought this headphone assuming it supported low latency mode - so I figuren I’d be great for gaming too - because that’s what reviewers claim. But they don’t. Sennheiser’s marketing team should really point those mistakes out if they’re going to be commenting on reviews.

You fail to grasp that it is not the claim but the lack of substantiation, as I've pointed out 3 times now. Their claims are empty if they cannot specify the technicalities that make them equal or superior.

That's an opinion shared by no one else. Good up to maybe $500 closed backs, let alone all open and closed back models.

Really they should have gone 2.4 GHz or at least LDAC. Basically kills any use they could have had for gaming as every other headset geared towards that is going to have much lower latency.

I would have paid more for lower latency and truly lossless playback.

I would’ve already bought it if that were the case. It’s truly odd that no headphone does both: you can either have gaming headphones with a 2.4ghz dongle but they’ll sound bad, or other headphones but they’ll he bluetooth and so unusable for gaming because of the lag.

The claims are not empty. My impression is that you just want to after some reviewer by spitting hairs. And btw you also fail to substantiate your claim. Again: Most closed backs measure horrible. Even the really expensive ones. It is not hard to beat most of them.
