Final Audio A4000 Earphones, with detachable 2 pin over ear fitting cable. A4000 fit very small - they are shallow and feel ultra lightweight, do not stick out at all for us and you can barely feel them in your ears. A4000 provide very good audio clarity with a fast and even bass (no bass boost).
The detachable cable is very well made with custom 2 pin connectors, resists transmitting noise and is extremely light and flexible. Final A4000 vs A3000 - A4000 provides more natural and improved vocals and midrange clarity.
