Elatchian Veeramani , via OnePlus 6 , Jun 12, 2020 : My Op Device: OnePlus 6 - 8GbRam Variant BWZ Purchased on : 02/06/2020 Review after 10 Days of Usage : 1.Usage: I Would Say BWZ was preferably made for Op devices especially from Op7 series. The reason behind that was The difference b/w HD AAC and Dolby Atmos* which is supported from op 7+ series only. That will give u the Exact Sound Tune and Quality they made using Single 9.12mm driver. 2. Connectivity: Tooks 2-3 secs for me to pair with my Op6. 3. Sound Quality: Average. I would say Clarity is there but not the quality. Don't expect More for this price Range. 4. Buttons: Quite sticky. Doesn't felt that click. 5. Battery Backup: Same as expected the battery backup is excellent. But I would like to note a point: BWZ Battery Consumption is directly proportional to the Distance of the BWZ from mobile. If u are at the verge of 10-12 mtrs surely battery will last within 2-3hrs from 100% charge. I have tested this twice. 6. Design and Make : Excellent Design. Cables are smooth and Strong. 7. Charging: As scripted 10 mins of charge will surely give u 10hrs of backup. it took 30 mins to fully charge using my Op6 dash charger.
