Baseus Eli 15i Fit with an open-ear design, achieving high-quality sound with HiRes Audio and LDAC support. - Model Name: Baseus Eli 15i Fit - Features: Open-ear design - Sound Quality: HiRes Audio, LDAC support - Tuning: Japan Tuned - Contents: Charging case, earphones, USB cable, instruction manual Thank you for viewing. -------------------- Purchased and opened on 2025/7/16. Worn once and used for about 30 minutes, but I am selling it because it did not fit my ears or usage requirements. Released in February 2025, purchased in-store for 9480 yen. The protective seals on the earphones have been removed, but there are no operational problems or signs of use, and it can be used without any issues. I think it has sufficient performance for use with smartphones during exercise or everyday use. (However, please be aware of sound leakage due to the open-ear design. You need to be especially careful when you are next to someone on the train.)
