“Listening to music on the AF180s is a detailed experience. The AF180 is like the IEM equivalent of a nice pair of reference open-back headphones….The soundstage is broad and enveloping – never congested or claustrophobic like budget IEMs can be – yet it’s not so clinical that it’s boring to listen to. Treble frequencies have a zesty sparkle to them that’s never fatiguing…..while bass frequencies aren’t overt, there’s plenty of accuracy in low-end presentation. Big EDM bass drops extend into sub-marine depths with so much precision you can follow it with your finger…Worth a serious look and listen.”
