Haier N90 Sound and Connectivity

Sound and Connectivity

Sound-wise, the Haier N90 does not include a loudspeaker or a 3.5mm headphone jack, relying exclusively on vibration and downloadable polyphonic or MP3 ringtones for alerts. On the connectivity front, the phone lacks modern conveniences like WLAN, Bluetooth, and USB ports. However, it does include an infrared port, which was a common method for wireless data transfer in 2006.
