I've recently been using a Momentum 4 out and about and on the train. How would the 620S compare? I'd also be interested in these for monitoring when recording my guitar, in which case how would they compare to an HD300 Pro (which I don't have)?

Thanks. I'm not sure I see the point of that option though, there's not enough bandwidth in Bluetooth for 16/44 let alone anything higher. AptX is already filtering frequencies and reducing the dynamic range to accommodate Bluetooth.

I've just installed it too. It looks like there might be a bit of extra ANC on the slider, after updating it appeared to let me adjust for more ANC. I haven't tested it though. I really appreciate the 5 band EQ with the frequencies shown. I didn't spot "resolution mode", what does that do?

Dog barks and keyboard clicks are of course not low frequency sounds. It is low frequency sounds in particular that passive isolation performs poorly with and ANC is needed for, i.e. rumble of trains, jet noise or traffic. I had an XM3 and don't remember its ANC doing a great job for anything...

Thanks for sharing that piece of information. Fingers crossed for improved ANC.

I've never tried the old firmware and ANC seems to be working at least enough for a train journey for me. I never had high expectations of it other than blocking out low frequencies. I can assure you I am not deaf and I'm not sure all the hyperbole is particularly helpful. If the old firmware...

Apologies, I misunderstood. Having a firmware update that makes it worse with no way to downgrade must indeed be really frustrating. The latest firmware is the only one I've used. I'm too risk averse to buy any tech gadget on release day :) It seems common in many ANC cans that ANC cannot be...

If you have a defective headset, just send it back. Most consumer headphones, even the Bathys and 1000 dollar ML5909, are made on the cheap in China and also have their fair share of quality control issues. The grass always seems greener. Older models like the Sure Aonic 50 probably do have less...

I use my M4 for the train during commutes. The ANC is not as good as my old XM3, but it works to reduce the majority of the low end rumble. The sound quality difference is stark though. There's likely a compromise that has to found between ANC levels and sound quality.

Can you elaborate? People in this very thread are saying it's great. ANC is really designed to attenuate 100-1000Hz, the frequencies of airplane, train and bus rumbling.

Spot on, at least for now. Despite the price, the Bathys don't even offer LDAC, "we ran out of time" was the excuse that I read. Personally I'm not convinced I'd want to spend significant money on extra resolving power to bring out all those SBC/AptX artefacts (I have a Samsung phone).

As I predicted way way back in this thread, just as these phones were released, not providing this feature is leading to many lower scores in the media, for example: https://www.rtings.com/headphones/reviews/sennheiser/momentum-4-wireless Audiophiles are happy to mess with EQ, but consumers...

This sounds like a problem with your lightning to USBC cable, maybe try another brand?

It's basically fraud.

I have an RME DAC that comes with a set of "bit perfect" test files. They are intended for checking software more than hardware, but nevertheless I tested some cheap USB2 cables from Amazon and they passed. Similarly, one could demonstrate no difference between USB2 and 3 for audio. That's the...

USB2 has more than enough bandwidth at 480Mbps. That's 1000 times AptX Adaptive. So USB2/3 won't make a difference, even with high-res lossless.

Not my experience at all. I lock LDAC at 990kbps for my Sony headphones and I've only ever had a dropout when in large crowds of people (presumably too much interference). LDAC has a fantastic bitrate, 990 is more than twice the max bitrate of AptX Adaptive (420). AptX Adaptive isn't even...

Thanks for the review. Do you think the Bathys would be better suited to classical or jazz music, especially orchestral music? It sounds like the usual "fun" versus "analytical" dichotomy. Those of us that love e.g. the HD800 when chained to a desk, might then go for the Bathys instead of PX8.

Samsung sell more Android phones than anyone else, they provide LDAC but not aptX adaptive or aptX HD.

Yes, it is certainly not unique to the PX8, but cannot be taken for granted either. Older Sony headphones did not support this, for example.

Yes most mainstream published reviews are not really worth reading. The authors are hired based on having a way with words, rather than having technical know how or passion for the subject. This of course does not apply to specialist sites such as soundguys and rtings (both excellent). This is...

I suspect that review is misleading here, was AAC "tested" on an iDevice or Android? It's true that AAC is bad on Android because of the encoding, which is hard to do well on-the-fly. But if the PX8 are given a good AAC source, e.g. from an iDevice, it should be fine, AAC decoding is a solved...

This review has some inaccuracies, for example "USB-C to USB-C for charging". That cable is not just for charging, it enables the use of USB for digital lossless audio. A quick glance at the manual is all that's needed to learn this. Many headphones don't allow this, but it is a significant...

The review is disappointing. Plugging an ADC cable into a analogue out on a Mojo also seems daft when one would get better results with these phones by just plugging directly into the source with USB. There's also no discussion of the sound profile or comparison to other headphones.

Yeah I'm not paying that price for something that is only going to support basic AptX on my Galaxy Ultra. No LDAC and no AptX Lossless for upcoming phones either. I'll pass for this round of updates.
