COWIN E7 BLUETOOTH HEADPHONES,ALMOST NEW, PERFECT CONDITION, IN NOIDA

For sale, Cowin E-7 Bluetooth headphone with active noise cancellation, purchased less than a month ago. Selling with box and online invoice. Perfect condition, used less than 15 hours, warranty is still valid. No scratches/dents/anything. On-ear headphones, very comfortable even for long duration. Active noise cancellation blocks off ~75% of ambient noise. Charges on USB, and battery lasts really long (I haven't had to recharge it even once yet). Sound quality is really good for the price. Selling because these are bass-strong, and I prefer headphones that are high on treble.
