Bought these pair of earphones a few days back. Simple review to give u guys a clear idea.
Build- very good(on par with any other sub 1.5k earphones) Overall sound quality- very good. Bass- more than enough.(more on it later) Mic- working as per expectations.(no complaints) Control buttons- good quality buttons working fine.
Most recent earphones i used were Jbl's T210 pure bass, so switching to these, my expectations weren't high. But the mi earphones delivered. Out of the box build quality is very good with braided cable n good quality plastic(braided only till the mid joint though). The BASS was very overpowering (i like neutral sound signature), gave me a headache after an hour or so. So tweaked it through the default android EQ. Its much better now, the vocals r VERY clear, TREBLE is good, bass is undercontrol n even the mids r clear. All u bass lovers will definitely appreciate these. But if u are a neutral sound lover, mi8 have to work on the EQ. Noise cancellation is decent enough as well. Overall sound quality n output definitely rivals earphones(sub1.5k) from brands like Jbl, skullcandy, boat etc but not better than Sennheiser and sony though. Definitely a value for money.
The only gripe is that the warranty is of 6 mnths only and the earbuds cld have been of better quality.
P.s - I've used earphones from Sennheiser,jbl ,sony,skullcandy,philips,razer,steelseries and boat. Current device Mi A2.
