Don't need that fourth pole? Clarito are the headphones you want...
This is an interesting sideline from one of my favourite manufacturers of smartphone headsets. ROCKJAW have produced the stunning Arcana v2 and Alfa Genus headsets in the past, with a forth pole on the 3.5mm jack, for microphone and media control of course. Audio quality from each of these is exemplary and there's really no need to spend more than a few tens of pounds for other in-ear headsets - the Arcana v2 have been my go-to reference headset across all smartphones now for almost a couple of years . Now, the Arcana v2 have been discontinued, but the Hydra v2 are very similar and only a few pounds more. Now, what's this? Clarito is a cheaper budget version of the old Hydra/Arcana v2 design, but with standard 3-pole jack, i.e. there's no microphone and thus are aimed at wider headphone use. (Yes, you can use them with a smartphone, but you'll have no pause control or way of picking up a call.) There doesn't seem to be a compromise in audio quality tho
