Build Aspect

OPPO Enco M31 is a quality offering from the tech giant and these pair of wireless Bluetooth earphones come laden with some serious tech and features for the price. The earphones are built from premium materials and look fabulous in both the color offerings. Compact buds and a neckband which is rubberized add to the overall comfort and these earphones can be worn for extended duration with no fatigue at all. Furthermore the buds have a spun metal finish on the outside of a contrasting color which add to the niche of the earphones. A playtime of 12 hours means that the battery capacity is decent. Available in Black (with silver) and Green (with gold) colors.

Performance Aspect

With tech such as Hi-Res certification, Titanium composite full-range drivers, Active noise cancellation for calls, a plethora of codec support you get a whole lot for your dough. The sound through the M31 is revealing and very transparent. Similarly the magical tuning brings out the best in mid-range too without ever sounding dull or flat. And for the bass heads the ENCO M31 has a boost mode too. Moving on the highs and treble have great extension and although its not overly sharp it has just the right tune to keep listener engaged. The active noise cancellation did not seem to work effectively as essentially the earphones still transmitted plentiful unnecessary background noise. Ultimately it can be inferred that the OPPO M31 are one majestic pair of earphones which has got lots of bells and whistles and perhaps are one of the best wireless earphones under 2000 Rupees in India.
