4.0 out of 5 stars Excellent headphones but with a catch!
By Karthik on 28 June 2020
Ok first let me get some things out of the way. The mic volume is too low. I tested it by recording my voice through the headphones once. It does reproduce the SURROUNDING sounds well but my voice itself was too low in the mix. I also attended a call once and the other party only kind of heard me so I switched to talking through phone.

Now that's out of the way, the sound quality while listening to music is just...GREAT. I initially bought the OnePlus Z wireless and while that sounded good, I always felt that it was a little muffled. But THIS sounds warm, full, tight, and reproduces all frequencies well. Add to that the headphones are light weight and fits well in the ear, the whole thing is a pleasant experience. I don't mind that the mic doesn't work well. In fact, I don't usually use headphones for calls so it's not a big deal for me anyway.

I got all the earbuds, plus the charging cable with the box. And the price I paid was 950. That's a steal deal considering just the quality of headphones I got.

If you don't mind the mic performance, just grab this when it becomes available (there's a chance that the mic in the item you get might actually work). Now if the actual headphones itself isn't working well, that could be a problem :D. But I believe that Amazon wouldn't sell those pieces in the first place. In any case, you got 10 days to decide!

Edit after using for a few days:
I thought I'd make a comparison with OnePlus wireless Z headphones since I've used both -
* Battery life could be better. As it is, it's FINE but the one in Z would last really long; you'd forget about charging the battery and it gives 10 hr play on 10 minute charge. That kind of freedom is missing here.
* The bass is implemented in different ways in these devices. While in M31 it is sharp, precise jabs, in Z it is BOOM-y, like you'll feel the headphones vibrating in your ears with the music (which I kinda liked). There is no distortion in either headphones though.
* Build quality is inferior to OnePlus Z. It's still fine and should last long if handled properly.

If I had to choose between the two, I'd still choose the M31 for its AMAZING sound, even for its full 2.3k price. But depending on your needs, the OnePlus Z could be a better option for you based on the above mentioned points.

5.0 out of 5 stars New and better than OnePlus Bullets Z!
By Omkar Narvekar on 28 August 2020
The earphones are fantastic!! The earphones that I'd received had no scratches or smudges. They were literally brand new (but of course, unboxed).!! I also have the OnePlus Bullets Wireless Z so, I'm eligible to dia a comparison between them.
These earphones are really very comfortable to wear, far more comfortable than the Bullets Wireless Z. Also they are very light weight.
The sound quality is just amazing 😍 The bass mode really enhances the bass quality. Oneplus bullets are clearly no where near these earphones. The mic is also working pretty fine. The build quality is slightly inferior to the OnePlus Bullets Z but still the quality is really good! In terms of battery OnePlus is clearly the winner but still 10 hours of battery backup in the M31 is pretty good too. The switch function works perfectly. If you're confused between the Bullets Z and the Enco M31, I'll highly recommend you to go for the Enco M31, you won't regret. These are clearly the best headphones under and around Rs 2000!!

Tip: I would suggest you to go for renewed model as most of the time, you'll receive completely unused product and you'll be paying 500-600 rupees less! And in case if you get a faulty item and you can easily return it!
