The Nubia M2 Lite has decent speakers all around. The speaker provides good volume during conversation in a silent ambient, however in a noisy market you will have to speak a little over the normal tone to let the person on the other line hear your voice clearly. The earpiece is audible enough under all surroundings and the and the noise cancellation on the in-built microphone is also quite good. While streaming videos or music on the phone, the bottom firing speakers retain decent sound quality even at the highest levels. The only problem that we faced is while playing games as our hands covered the single speaker grill most of the time the sound gets muffled.
