Review on Affordable HONGZAN Bulk Earbuds for Classroom - 100 Pack, Wholesale Earphones Individually Bagged - Ideal for School, Library, Computer Lab, Museums, Both Students and Adults - Black by Mdl Thurston

I purchased this kit to use with a laptop and cell phone. Two sets stopped working straight away, 1 the same day and another a week or two later. I have given away 2 other sets so I cannot comment on their quality. 20 percent of a known defective product is unacceptable. Revain kindly gave me a $5.00 credit as I was unable to return all of the headphones. The headphones are very comfortable, the sound is sufficient for the headsets I currently use. I will probably not order this brand again.
