RONIN | R-140 | EARBUDS

Driver & Sound — The R-140 uses a 10 mm speaker driver, capable of producing dynamic sound with reasonably solid bass and balanced output for music, podcasts, calls — acceptable for its price range.

Connectivity — It supports Bluetooth version 5.3 with about a 10-meter wireless range, ensuring stable pairing and wide compatibility (Android, iOS, and other Bluetooth devices).

Noise Cancellation & Mic / Call Quality — R-140 offers Active Noise Cancellation (ANC) and Environmental Noise Cancellation (ENC) features, along with a quad-mic setup for calls. This helps reduce background noise during calls and delivers clearer voice quality when calling or in video-conferences.

Controls & Features — There are touch-controls on the earbuds allowing you to manage music (play/pause, skip), handle calls, and invoke voice assistants (Siri / Google Assistant) without needing to touch your phone.

Latency & Gaming Mode — R-140 supports a “game mode” / low-latency mode for more responsive audio, which can be useful when watching videos or playing games.
