Secondly, the price of this kit is really affordable and roughly equals the price of ordinary middle-market headphones. After you have created the perfect seal in your ear with one of the rubber tips, they sound really loud and clear enough. Their built quality also seams to be substantial, as the buds are waterproof. Also, there is no sound latency, which is good for watching movies or YouTube.
They come with a portable power bank that has a built-in 500mAh rechargeable li-ion battery (charges for about 3 hours). The manufacturer promises up to 8 hours of continuous talk time. The wireless ranges up to 10 meters (yet, note that if you cover your ear with a hand or something like that, one earbud might stop working), and the Bluetooth version is 4.0. In sum, TWS earbuds sound decent for the money and will make a good substitute to their messy ancestors.
