I am writing this comment after using this SAMSUNG LEVEL U earphones for about 2 months. I brought these earphones from samsung store @2999/-. Sound quality of this earphone is just fantastic. it takes approx 1 hr to get fully charged and delivers backup of 2 days ( as per my usage 4 hrs a day) .it has noise cancellation technology. Quite durable design and build quality is also excellent. In the box I got earbuds of 4 different sizes , no charger and no datacable included in the box. For me this was a value for money purchase.
