【Open Clip Ear Design】OICGOO open ear earbuds are completely open design, no need to go deeper into the ear canal, they will not bring pressure to the eardrum, are more breathable compared to in-ear headphones, and are more comfortable to wear. And you can sense the changes in the surrounding environment while listening to music. Wearing glasses while running/riding won't affect the use of the headphones either. 【Lightweight and Secure Fit】Bluetooth earbuds are made of highly elastic skin-friendly materials. A single earphone weighs only 0.2 ounces. After extensive ear mold testing, the weight is evenly and reasonably distributed, which ensures a more stable fit on the ears. And more comfortable to wear, with no pain even after a long time wearing. 【Bluetooth 5.3/Noise-Cancelling Mic】Bluetooth 5.3 technology ensures a more stable connection and longer transmission range (≥15m), as well as lower power consumption and latency, together with a noise-cancelling microphone, allowing you to make without delay HD stereo calls. 【Lossless Audio Quality】OICGOO open bluetooth earbuds adopt the latest directional audio technology, which can automatically adjust the propagation angle of the sound beam to make the sound more focused, clear, and three-dimensional. In addition, the wireless ear buds retain the classic shape of a semi-in-ear headset, effectively avoiding sound leakage compared to the rounded shape of other ear clip earbuds. Bring you an immersive music experience. 【8 H Long Life&Wireless Charging】 The single headset can be used continuously for 8h under full charge, and with the charging compartment, the battery life can be up to 32h. It adopts Type-C fast charging, which can be fully charged in 2 hours. Support wireless charging.
