I'd avoid, even if they happened to do this.
This may be subjective. Bose might sound good to some people's ears and less good to other people's ears.
I personally prefer corded headphones and mains powered speakers, but if I were to buy a small wireless speaker I would buy a cheaper brand and ideally second hand, because this category of devices are basically consumables.
Sound quality is not the same as music quality.
To be more specific, Sound Reproduction Fidelity is not the same as Pleasant Music
To be even more specific, Signal Reproduction is not the same as "Pleasant Sounds*
The goal of music is not always high fidelity of reproduction; if it were, over-driven valve amps would never have been a thing.
The only thing objective in this context is signal reproduction, which is not the highest concern for music production.
A good example of this is a target curve, often used in room calibration. Dirac has a good explanation: https://www.dirac.com/resources/target-curve
(highly recommend Dirac room correction, by the way)
I am very happy with my QC-35 headphones. They are probably 5y+ now and they go with me everywhere. I think it is unfair to state their hw quality is low. It is much better than low.
Until quite recently, they were widely one of if not the most recommended wireless headphones. The new Sennheiser's that come with a USB-C dongle might have finally stepped past what Bose has been delivering, but at a higher price.
They are such a standard response that presumably a real audiophile will come along to point out that their favorite model is much better, than a particular well known Sennheiser model, but as far as one can say in brand terms they are solid.
All the Chinese-made Sennheiser stuff has awful QA.
Also, there are multiple forums and subreddits you can ask this question on. You will get more answers than you would from me and the rest of HN.
Their build quality is exceptional, and they're built like tanks. The only problem, imo, is the Beyer house sound is very shouty and fatiguing, especially with the "990" versions of the product line over the years.
Disclaimer: I owned a Beyer DT880/600ohm (the neutral one of the 770/880/990 siblings), paired with an amp that could properly handle it. Its one of the few headphones I sold and did not retain in my collection, it deserved someone that could love it. The new Tesla-based drivers are better (such as that 1990), but still retain that Beyer sound.
I recommend HiFiMan Sundara/Ananda if they fit your head and there aren't any CPU fans in your room.
