build and design is good. lacks a bit of base as i have always been a sony fan and a huge fan of its extra base. battery back up is upto 8-10 hrs and depends on the useage. overall this headphones produce a very sweet sound like the other Sennheiser products, provided that you manage your equalizer well. hope this helps.

just awesome, Sennhieser thanks for making such a good product, looks classy and comfort for ears and bass is also good

Superb earphones. Very good wireless range. Top notch sound quality. Qualcomm aptX - very low latency. Very good bass ( i don't know why people are saying it doesn't have bass). Over all, one of the best earphones available here.

It’s great for music but.. but it’s not great for handling phone calls.. Other person can hear lot of background noise.. Around the neck, it slides towards heavier end(left)

It's a good product with a great sound. Built quality is also satisfactory and sennhesier has a great team which addresses your issues with products neatly. 2 years warranty is something you can count upon while investing a good amount of money on an earphone. To be precise about the performance you can identify each instruments sound separately.The only problem is it doesn't have a great bass.So if you love a bit of bass then go for some other brands. In my own case I underestimated my "...

fantastic deal , 1no. products, Bhai Bluetooth earphone bole to Sennheiser is the best for soud Quality. specially for bass lover, thank you flipcart. for one day dellivery

Firstly Kudos to flipkart for its delivery in almost 24 hr..... It is quite light and phenomenally balanced designed earphones with the premium sounds of Sennheiser... The bass is clean as per the song the treble mids are good with warmth and balanced sound and a good battery life of about 6 hrs

Product is good but Flipkart given box condition is too worst condition,it's full of dust,box too damaged,still I need to check product functionality.

These earphones are great but does not work well with iPhone XS. The bluetooth is good for listening to music, but not suitable for calling as the voice quality is not good, when compared to the Apple earphones.

Awesome product
