Finally got the bloody thing working. To be honest I don’t have much of a clue what I did or how long it will last. The trick seemed to be unplugging all the other HDMI kit (as the app finally told me to do).
I’ve been sniffing around posh Bluetooth headphones (Sony WH-1000XM5, Sennheiser MOMENTUM 4 - does anyone have any experience?) and while reading reviews saw WHF (calm down, calm, down) saying that Sennheiser HD 250BTs are a bit of a no-brainer for the money.
Noticed that they’d gone down even further on Amazon (prepared to sacrifice ethics for munneh) with Black Friday so took a punt on a pair. If they turned out to be rubbish then the wife already wants them to replace her utterly knackered MS Teams headset.
Anyhow, just set them up and for £26 they seem ridiculously good.
The bass on Zion Train’s Follow Like Wolves is a bit over-emphasised. Duolingo is maybe a bit reedy (I think they use very low bitrate samples). They’re maybe a bit tighter than I’d like on my (admittedly massive) head.
But yeah, for £26 the wife can buy her own headset - I’m keeping these.
