The WF-SP900’s are durable and stylish despite their small size, yet still deliver crisp, clear sound thanks to the newly developed Sony original Balanced Armature driver units – letting you enjoy your favourite tunes when enjoying sports.
The WF-SP900 headphones introduce an intuitive operating system with tap operation or button operation, so you can easily turn the volume up or down by double tapping and play, pause, skip to the next song, or return to the previous song, etc. with the buttons.
