Expert Verdict
The M1454S2 is a 3.85V, 105mAh lithium-ion battery pack (2 pieces) designed as a replacement for Bose QuietComfort Earbuds II and Soundsport Free. It is rechargeable and affordably priced, but requires periodic monthly use or proper storage to maintain health. As a budget Chi-Fi IEM accessory, it serves its niche well for extending earbud life.
