2-Pcs Battery for Sony NC-5WM NC-6WM NH-9WM NH-10WM NH-14WM 1-528-231-11 WM-701C WM-EX921 D-E888 D-E900 D-E905 D-E990 D-E999 WM-RX707 WM-F100 WM-FX675 Walkman Player Gumstick

Just jumped for these this week on a new player to me because they’re actually 1.2V which is precisely what these players want for the most part. Buy I have a cradle I specifically bought that charges this battery while in the player so no need for USB-C to recharge.
