5 star review in the UK national newspaper:

“While most in-ears commonly feature a single driver, the Primo8s pack four balanced armature drivers in each earpiece. With a single driver each for the mids and treble, the remaining two deal with bass frequencies, cleverly addressing the usually disappointing low range performance of this type of headphone.”

“There’s a pair of Comply memory foam tips in the box that fit securely, even when jogging.  Once snug, the Primo8’s performance was indeed revelatory, delivering a range of wide detail rarely experienced with any sort of earphones, let alone in-ears.”

“Both clean and revealing, yet full of low end and mids, I picked out elements I’d never noticed before in familiar tracks.”

“The precise, unexaggerated tone the Primo8’s deliver lives up to their growing reputation.”
