Disclaimer: I bought these using money out of my own pocket, so you can trust every word to be my honest opinion.
6 May update: Apple just released firmware rev. 2D15 today and the volume issue is still not fixed.
Twelve South makes great accessories for your Apple devices. One of their latest products is the AirFly Pro – a bluetooth adapter that acts as both a transmitter and receiver.
The transmitter function allows you to transmit audio from any device with a 3.5mm audio jack to a pair of bluetooth headphones. Like from an in-flight entertainment system or a Nintendo Switch to your AirPods Pro for example.
The receiver function allows you to transmit audio from your Mac or iPhone to any device with 3.5mm line-in jack.
Don’t buy these right now
I bought these with money out of my own pocket, so unlike other “reviews” on other sites that have been sent samples and simply regurgitated the press-releases, I’ll cut to the chase and tell you why you should not buy these – not for the time being at least.
If you want something to connect your Nintendo Switch to your AirPods Pro, I highly recommend this Gullikit transmitter.
They have a low-volume problem when used with AirPods and AirPods Pro. And it’s a deal-breaker.
Twelve south places this warning in the FAQ section on the bottom of the AirFly Pro’s product page – as if most people would bother to read it. The suggested workaround of raising the volume of whatever device you’re connecting it to to the maximum does not help either.
Raising the volume to the maximum on in-flight entertainment systems introduced terrible distortion, while making dialogue barely audible.
Raising the volume to the maximum on my Nintendo Switch makes the audio barely audible on public transport and takes away any immersion in games that I was playing.
I reached out to Twelve South and it seems like there is no ETA for this fix. I’ll update this review when it eventually does.
