Description
Description
The evolved in-ear speaker system, the SRS-002 earspeaker SR-0002, builds on the original S-001 and its successor, the S-001Mk2, with a diaphragm that's approximately 15% thinner and lighter. Combined with its bold design, it delivers high-quality outdoor listening. The SR-002 features an improved ear pad design for a more comfortable fit, and comes with three types of ear pads (earpieces). It also includes a dedicated overhead arc headband for a more stable fit.
The newly designed driver unit SRM-002 has an improved power supply, which means that it can be used with alkaline batteries as well as rechargeable batteries with low electromotive force, providing sufficient performance. It also allows you to switch between eco mode and normal mode, allowing you to enjoy different sound quality variations. Also, a polarity-unified AC adapter is available as an option (product name: AC-4.5V) so that you can use the product without worrying about battery consumption.
*Depending on the type of adapter, it may not be usable.
