Yep, the Sony WH-1000XM4 headphones can indeed connect to multiple devices at once.
It's all thanks to this cool feature called multipoint Bluetooth connectivity. So, basically, you can keep them paired with two devices simultaneously—like your phone and laptop. Picture this: you're jamming to some tunes on your laptop, and your phone rings. With these headphones, there's no stopping the music to switch over manually; they handle the switch for you automatically.
Now, there are a couple of things to keep in mind. Our research shows that if you use this multipoint feature, you won't get to use the LDAC audio codec, which offers really high-res audio. Instead, it'll use SBC and AAC codecs, which are still decent but might lack some of the detail hardcore music lovers crave. So, if you're super into audio quality, you might have to sacrifice a bit of that for the convenience.
Also, be aware that while it's meant to seamlessly switch between devices, some folks have run into occasional hiccups. Sometimes, there are delays or you might have to tweak some settings to get things working smoothly. It can be a bit annoying, but it doesn’t happen all the time.
If you do decide to use the multipoint connectivity, the Sony Headphones Connect app is definitely worth exploring. It helps you manage device connections and tweak noise-cancellation settings, which can make a difference with performance and connectivity.
All in all, the ability to pair your Sony WH-1000XM4's with multiple devices is a handy feature, especially if you're someone who frequently juggles between gadgets. Just be ready for some trade-offs in sound quality and maybe a bit of fiddling to get everything just right.
