The handsets support GSM SIMs of frequencies 900 / 1800 MHz Display screens for these handsets are 2.4 inches screens with 240 x 320 pixels resolution but lacks accelerometer and proximity sensors. The MS727 Soul has a QVGA touchscreen display while it's much more compact and easy to work with in X222. Even though the X222 is good in looks, its 0.3 megapixels VGA camera is disappointing while Maxx MS727 packs a 1.3 megapixel camera with better quality image captures and featuring digital zoom and a max resolution is 1280 x 1024 Pixels.
Supposedly MS727 has better media players as well. Even though an average handset, the MS727s Video player supports Mp4 videos as well besides 3GPP which is the X222's only video format support. Both their audio players support Mp3/WAV/AMR formats. Internet browsers are smoother in Maxx MS727 which features a WAP browser and an alternative browser, the Opera Mini. Both the handsets have FM radio with scheduling and recording features. These handsets apparently don't support Email facilities but SMS/MMS features are provided. MS727 has better SMS features than X222.
MS727 comes with 2 GB micro SD card preinstalled memory, the same as that of X222 and is extensible up to 8 GB. The sound output from the loudspeaker of these phones is good. But X222 has a bit more audible sound output while MS727 offers greater clarity to the audio. Obviously these handsets aren't 3G compatible. The handsets only support GPRS connectivity. The Bluetooth versions in the phones are ordinary but reliable. Micromax mobile handsets are famous for their battery efficiency. But this time, MS727 apparently rivals the battery efficiency of X222. Both of them offer almost 6 hours talk time and the standby time of X222 is better as it lasts up to 157 hours.
Micromax X222 has a very decent and attractive price in India tag of Rs 2,500/- while Maxx MS727 is a bit more price in India of about Rs 3,350/- approximately.
