Karbonn A9 Audio and Connectivity

Audio and Connectivity

For audio, the phone included a loudspeaker and a 3.5mm headphone jack, ensuring compatibility with standard headphones. Connectivity options included Wi-Fi 802.11 b/g/n for internet access, Bluetooth 2.1 with A2DP for wireless audio, FM radio, and a microUSB 2.0 port for data transfer and charging. The integration of GPS provided basic navigation features but could not be enhanced by the absence of NFC technology.
