Verdict

The Amethyst MD3 is a compact, cube-shaped portable Bluetooth speaker measuring 80 x 85 x 90 mm and featuring a single 4W driver with a frequency response of 80Hz to 20kHz, an onboard touch control interface, and a built-in subwoofer. Its primary advantages include flexible playback options via Bluetooth, NFC quick pairing, a 3.5mm AUX input, and a micro SD/TF card slot, as well as handsfree speakerphone capabilities and a decent 2200mAh battery that delivers 6 to 8 hours of playback time. On the downside, the speaker relies on an outdated Bluetooth 2.1 protocol, lacks true stereo sound due to its single-driver configuration, suffers from a lengthy 4 to 6-hour recharge time, and delivers a slightly weaker mid-range and lower-end bass kick compared to its larger counterparts.
