The Jabra wireless earphone is just amazing!
This earphone uses dual-core noise reduction, two chips work together, which is more effective than one chip, and the speed of processing noise is faster! In addition to shielding external noises, it can also eliminate internal noise (breathing, heartbeat, chewing). The 11-level noise reduction mode allows me to freely switch to the most comfortable noise reduction mode in various environments.
One more thing I have to mention about this earphone is its semi-open design. Many people may not know that Jabra is a Nordic earphone brand with a hearing aid background, so in fact, the earphones designed by his family care more about comfort and safety than other earphones. The stethoscope effect and ear plugging effect that everyone has always criticized are no longer present on this earphone. I deliberately checked it out. This earphone used a medical-grade molecular laser to drill the pressure relief hole so that the pressure in the ears can be drained, so it is naturally more comfortable to wear and has a stronger noise reduction effect.
Jabra’s exclusive ear gallery button lock design relieves ear fatigue. They think this earphone can fit your ear canal (lock) perfectly like a key and does not rely on hard pushes. It can be worn with a single twist, and it will not fall off no matter how you shake it. The details are really attentive!
