Nokia has officially launched three new Nokia feature phones – Nokia 5710 Xpress Audio, Nokia 2660 Flip and Nokia 8210. Among them, Nokia 5710 Xpress Audio is the most interesting as it contains TWS headphones and a charging case inside of the phone body. The Nokia 5710 XA looks like a classic candy bar-style phone from the front, with a 2.4-inch TFT screen and the classic T9 keypad. But at the back, there is a load compartment, visible by sliding the plastic cover. The charging compartment is used to charge the TWS headphones which provide up to 4 hours of music playback or 2.4 hours of talk time per charge. Nokia 5710 Xpress Audio's removable 1450mAh battery provides up to 6 hours of talk time on 4G networks and up to 20 days of standby time. Other features include 3.5mm headphone jack, Bluetooth 5.0, 128MB ROM, 48MB RAM, dedicated music control buttons, wireless FM support, and micro USB port. VGA Camera is at the back. The device comes with the Symbian S30 operating system and supports microSD up to 32GB.
