The BOROFONE BC20 “Smart” is a compact mono Bluetooth 4.2 headset designed for clear, hands-free calling at work, on the road, or on the go. Powered by the WT200 platform with classic headset profiles (HFP/HS, A2DP, AVRCP), it pairs quickly and stays stable up to ~10 meters. The 70 mAh battery delivers about 4 hours of talk/music and up to 120 hours standby, while a quick ~1.5-hour recharge over DC 5V keeps you moving. Its slim ABS body and lightweight single-ear fit make it comfortable for long wear—an easy, budget-friendly choice for Android and iPhone users in Bangladesh.
