What the Samsung Galaxy Buds4 Pro is worth

The Samsung Galaxy SM-R640 is a True Wireless Stereo (TWS) in-ear headset with Bluetooth 6.1, designed for calls and music, featuring an integrated microphone and a USB type C charging case.

The measurements point to durability and battery life: IP57 rating, active noise cancellation via 6 microphones, and up to 30 hours of continuous audio playback with the case (ANC off), or 26 hours with ANC on. Talk time reaches 22 hours with the charging case. Each earbud weighs 5.1 g, with dimensions of 18.1 x 18.1 x 30.9 mm.

The device also includes an accelerometer, gyroscope, position sensor and proximity sensor, along with adaptive EQ and voice commands.
