These pair of headphones represent true value for money.
Excellent bass, a surprisingly good noise cancellation feature (not as good as Bose QC 35 II tho), comfortable earpads leading to hours of continuous music playback, excellent value for money overall.
My only gripe is the fact that the headphones don't fold up and they don't come with a hard case (although the soft carrying case is gorgeous).

Sound is very well balanced and clean; comfortable to wear ;the Noise Cancellation is more than decent ; battery life is very good and all of this makes the headphones a great buy and excellent value for money.
Good features but design could do with some improvement . Aesthetics are not very appealing as compared to say comparable headphones such as Bose , Sony or Sennheiser which are thrice as expensive as the Plantronics BackBeat Pro 2 in India.
If you aren't a really serious audiophile and a frequent (long distance ) traveller , go for this headphone.

I got to test a few best selling headphones models in the market except Plantronics (unavailable for demo).
Few things about the ones I tested. JBL E65BNTC was good performing with decent bass which suited me. I even thought of going for it but I hated it's design. Moreover I had almost made up my mind to go for PLT. JBL's other models in the price range were also decent performing in contrast to thier entry models which in my opinion perform below par as compared to their competitors.
Sennheiser HD 4.5 were good looking though it didn't feel premium like its pxc 550 model. People have different tastes in acoustics and therefore let me take the liberty to say that sound were not very impressive though won't be disappointing. Maybe it's their pricing that made me expect more from it. PXC 550 Noice cancellation were exceptional so were Sony's WH 1000XM3. No headphones in below 20K segment can match their ANC. Not even close. In case of performance Sony's flagship is well ahead.
Sony MDR XB950 would satisfy bass heads rather than those looking for refined sound.
Now coming to PLT BB 2, first thing I noticed while unboxing was it's weight. Yes it was mentioned in almost all reviews but none of the headphones I tested weighed anywhere close to this. But the looks satisfied me, built quality were more than expected, durability; we'll see in future.
Sound quality was awesome, clearly beating Sennheiser. JBL too lacks refinement like them. Maybe it is the PLT's underwhelming bass which stops me from stating a clear winner. However the bass problem can be defeated by making use of eq settings in the music app that you use. I use Apple music and it's bass boost made a significant difference. ANC is par. Sennheiser HD 4.5 might be a better option in that aspect. PLT'S extra sensor features are annoying as I already turned them off.
Concluding, PLT BB2 is a great pair and I liked them. I bought it and I'm gonna keep them.

Impressive set of features for the price.
Design - U either love it or hate it, decide for yourselves!
Sound - Bass-heavy sound signature(liking it!), the ANC thankfully doesn't affect the sound quality
Noise cancellation - Not the best!
Microphone - Average
Connectivity - Impressive bluetooth range and connection speed but no NFC!
Overall, one of the best noise cancelling headphones in this price bracket.

(The smart sensors on the phones were not working out of the box. I was disappointed with the Headphonezone customer support team who had no clue about resetting it. Plantronics web support page however explains the procedure, and it worked!)

Amazing sound, good bass and is loud enough loved it totally worth buying thanks for the suggestion headphonezone

Absolutely feature rich multi-mode headphone. Sounds great both in BT and wired mode. Built beautifully. For the price it sells for we can’t expect audiophile quality. But it’s nice to listen. In the wired mode sounds really very good. With an Amp sounds real loud and clear. Features wise it has all the bells and whistles of higher priced models.
