Zebronics Zeb-Thunder comes with a plastic build and a matte finish.
The headband is also adjustable. All the Multi-Function buttons and the On/Off button is on the left earcup.
You will get 9hrs of music playback at 50% volume and these headphones get fully charged in around 2.5hrs.
Use AUX cable during low battery in headphones for non-stop music listening.
Sound Quality is good on these Headphones, vocals are crisp and clear, mids and highs are stable but I feel the bass to be slightly on the low side but leaving it everything is fine.
These headphones comes with Bluetooth Version 4.2 which nowadays is not in trend. Still the company claims that the operating range of these headphones in wireless mode is up to 10 meters.
