B&O's new Beoplay E4 are a noise cancelling earphone with 20 hour battery life & new Hybrid Noise Cancelling feature that is very effective. The E4 have a similar shape to the H3, for excellent comfort and ergonomics - they stay in place without feeling intrusive. There is an inline mic and controls, sound quality is excellent, with good clarity and the new noise cancelling, combined with the isolation the earphones provide on their own, is very effective.
There is little to no background hiss and a nice dead background for your music to play over, so you do not have to raise the volume to experience good clarity. Have used these on the plane and they provide impressive noise cancellation, excellent comfort and very good sound quality.
Includes M foam eartips, 4pr silicone eartips, carry bag, flight adaptor. 2 year warranty.
