Nowadays, wireless headphones are very common, but there are still some problems that cannot be avoided, such as unstable connection, short battery life, and uncomfortable wearing. If you are looking for reliable wireless Bluetooth headphones, the UiiSii BN90 neckband earphone is an excellent choice.
At present, there are precious few four-drivers Bluetooth headphones on the market and expensive. The UiiSii BN90 is the best choice for four-drivers with perfect sound, long battery life, stable Bluetooth connection, and the budget price. But perhaps for someone else, the headphone cable will be somewhat inappropriate.
UiiSii BN90 uses an ergonomic in-ear design. The earbuds are soft with rubber tips, which fit your ears comfortably and have some noise isolation effect. Even if you shake your head, it won't fall off easily. The neckband design provides great convenience and can prolong battery life.
The earbuds are made of translucent and black matte plastic. There is a three-button function key on the left cable and an indicator letter below the earbud for what ear the earbud goes in.
With the UiiSii BN90 dual-battery earbuds, 1.5 hours on a single charge can last up to 18 hours and 450 hours of standby time, providing you the power and motivation needed to fuel over a week of workouts.
UiiSii BN90 sound sounds great. It is designed with the quad drivers (2* dynamic drivers and 2* balanced armature drivers for each side) to perfectly emersion deep bass and crystal crisp treble. This unique design expands the frequency range of sound up to four times and recovers the original sound to the most extent. Its soft earplugs have a noise isolation effect. When you wear headphones to listen to music, you can hardly hear the ambient noise.
Built-in high-sensitivity MEMS microphone, there are without any problems in taking and making calls, and the call quality is clear.
Function and Accessories
The earphones support Bluetooth 5.0 and they are extremely easy to pair and more stable.
At the same time, the earphones also have an IPX5 rated for waterproof and sweatproof, so you don't have to worry about to damage it in wearing it outside in the rain or sweating it in the gym.
Regarding accessories, in addition to headphones, there is a UiiSii Carrying Case, 5 pairs of different sizes extra earplugs, USB charging cable and user guide.
Maybe some people want a wired quad drive headphone like 1more, but unfortunately, the bn90 is wireless. But in my opinion, wireless quad drive headphones are more convenient. So if you are looking for a budget pair of quad drive wireless Bluetooth headphones, then the UiiSii BN90 will be a good choice. Its sound quality, comfort, and battery life will not let you down.
