Why we stock it
Hybrid IEMs often sound like two teams that never met. The W4's crossover work is the whole story: the 10 mm dynamic hands off to the armatures so smoothly you stop thinking about drivers at all. Isolation is deep enough for a train, and the fit disappears within minutes.
Owner reviews
Rated 5 out of 5 ✓ Verified purchaseCoherent is the word
“My first hybrid that doesn't sound like a committee. Treble is present without ever stabbing. The 4.4 mm termination into the Wayfarer is a genuinely end-game portable rig.”
Rated 4 out of 5Fit takes a day, then bliss
“Took me a few tip swaps to seal properly (use the foam ones). After that, isolation on the train is deep enough that I missed my stop. Twice.”
