I like listening to songs very much. I like listening to songs with headphones everywhere, so there are many Bluetooth headphones. In-ear headphones, semi-in-ear headphones and neck-hanging headphones have been used for some time. Although in-ear headphones have better sound effects and strong isolation from the outside world, they will be very uncomfortable after being worn for a long time. Semi-in-ear headphones will eventually become worse in sound insulation and have good comfort to the ears, but they will always fall off inadvertently. Neck-hanging headphones solve some problems of the above wireless headphones. However, the pros and cons of everything are mostly in the same industry. The long earphone line always affects activities and makes the time for listening to songs imperfect. Fortunately, there is another Bluetooth headset technology-bone conduction technology, which is more suitable for outdoor sports than the traditional Bluetooth headset, and has become one of the important auxiliary devices in the great cause of slimming and reducing fat in summer.

Bone conduction technology transmits sound directly from the ear bone and jaw bone to the inner ear, and then transmits sound to the auditory nerve to cause hearing. The sound does not pass through the outer ear and the middle ear, which protects the hearing, does not hinder the external sound from transmitting sound waves through the air, and eliminates the swelling caused by the traditional in-ear style. While listening to music, it can also communicate with people around it, making it really painless to wear and making it look and feel the same. The industry-leading vibration sound sensing technology can effectively reduce the vibration of bone conduction sound and improve the sound quality under the condition of constant volume.

Open the outer packaging, South Carolina bone conduction CCII is made of titanium alloy aviation grade material, which can resist 360 violent bending and winding without damage. The whole earphone is 28g, which is a great blessing for friends who are allergic to rubber. When wearing, the audio bypasses the eardrum to transmit sound, and the ear canal is clean and refreshing at any time. Ergonomic design, multi-point support, comfortable and stable, jumping without falling off, ears without plugging, bid farewell to congestion.

In appearance, it is still an integrated ear-hanging type, which is the best design scheme of bone conduction headphones at present. Although it looks cool, the detachable ear-hanging type is not reliable to wear, and it is easy to shake when exercising, resulting in unstable sound transmission.

In terms of charging, the same magnetic charging scheme as CC Pro is adopted. Compared with the traditional tail plug charging scheme (namely, type-C and Micro-USB interface), the magnetic charging has no interface and no hole in the fuselage, so it can achieve better waterproof and dustproof effect. Runner CC II battery life is about 6 hours, fully charged in less than 2 hours, and charging speed is good. Runner CC II is equipped with a 150mAh battery, which has a larger capacity than similar headphones. Runner CC II adopts Bluetooth 5.0 chip, and the signal is quite stable whether indoors or outdoors.

Outside the right is the function button, above it is the switch button, below it is the volume increase and decrease button, and between the two buttons is the indicator light. Long press on/off key, short press play and pause: volume adjustment key, long press to cut the previous or next piece of music.

The fuselage is designed with professional ergonomics, with multi-point parallel support and comfortable wearing. The earphone is firmly combined with the human body and will not fall off when moving.

Of course, the Runner CC II in South Carolina is just a sports Bluetooth headset, and the sound quality cannot be so professional. If you also plan to have a Bluetooth headset that can't exercise, is waterproof and doesn't delay listening to the outside world, South Carolina Runner CC Ⅱ Ⅱ bone conduction Bluetooth headset may be a good choice.
