SONY LinkBuds S Ecru WF-LS900N Retail price: ¥26,400 This product was used in a CM featuring SixTONES. The box, instruction manual, earbud tips (all spare tips in photo 8 are unused), and charging cable are all included. The case and earbuds have been disinfected. Purchased in July 2022 and used for approximately 1.5 years. I charged them about once every 2-3 months, but I stopped using them when the battery life became shorter. Currently, the battery runs out after about 15-20 minutes of use after charging. The case's lamp sometimes blinks orange, but it charges without any problems. Functions like noise canceling work normally. There are no noticeable scratches or stains. Please purchase if you are comfortable with a used item and the battery issue.
