Final E4000 Final are building on the concept of the E-series to create high-sound quality with a simple design in a dynamic earphone. With the release of the dynamic E4000, the step-up of the successful E2000 earphones, Final have achieved a purer, subtler sound with more balance and clearer delivery. This version also includes a detachable audio cable with special MMCX connectors making the E4000 even more versatile. Tuned to reap pure and natural sound with balanced execution, the drivers of the E4000 produce natural and realistic sound that does not emphasise any frequencies in particular. An important role in this design plays the acoustic chamber inside the dynamic driver that controls the balance between the volume of low frequencies and clarity. With the uniquely designed swing fit mechanism, the earpieces of the E4000 can be swung left and right and tilted towards the audio canal for a perfect fit. This enables the sound to be transmitted directly to the eardrum for clear sound delivery. Realistic sound experience.
