It's a good article, but from reading this you'd think the downsides of bluethooth were merely a trade-off between bandwith v full fat hi-res (which you may not notice anyway) and extending range.
It misses out the (for me) single biggest issue in wireless and one that no review really touches upon - bluetooth isn't fit for purpose. It's a data-tranfer process, and not designed for music.
It works on the 2.4GHz band (for industrial, scientific and medical (ISM) - mainly to avoid paying licensing fees). It's a crowded space, and in busy areas it bounces around, reconnecting over and over again. I appreciate that WhatHiFi have amazing dedicated listening facilities in their offices, but these products are designed for moving around.
I cannot make it from one end of Liverpool Street Station (my twice-weekly commute hub) or Victoria Station (once a week) without at least a dozen, and usually waaay more drop outs. I'm on my second set of Shure Aonics - so maybe this is just a Shure issue, but I've really not had the desire to spend another £200+ to find out if other manufacturers have this issue.
I'd love to see testing of wireless products in busy stations and on tubes/buses, as a lot are bought for that purpose.
I've also got a Zorloo Z'tella and a Chord Mojo. The Z'Tella is good, but the bullet-proof build of a 3.5mm jack is far superior to the (frankly) skitish and fragile USB-c connection. The Chord Mojo is fine for aeroplanes, long train journeys and desk-based listening, but entirely rubbish for on the move commuting. It's a real conversation starter as a paperweight tho (which is what it's been for the past 3 years!).
