Since the first contact with bone conduction Bluetooth headsets a few years ago, I have gradually fallen in love with this category, although it is said that it and noise-canceling true wireless earphones are completely two directions, but it is true that in different scenarios, the advantages of bone conduction headphones are very obvious, especially if they do not enter the ear to protect hearing, and will not bring the extrusion of ear piercings and bacterial breeding, so I usually use it to listen**.
As the head brand of domestic bone conduction headphones, Nanka has also launched a number of series and models of bone conduction headset products, through different positioning and division, to meet different use needs, as well as different budget user groups, Runner CC series this time ushered in an update, upgraded to Runner CC4, various configurations and details have been improved.
Compared with the products of the early years, today's bone conduction can be said to be technically mature, whether it is in the configuration or the actual experience, it is a lot of progress, including the most important sound quality, sound leakage, call these aspects, this hands-on experience of the South Carolina Runner CC4 is a good example.
The core function of the headset is to listen**, and the core part of the bone conduction headset is the oscillator unit, which determines the feeling when you listen, Runner CC4 has been upgraded to AF full vibration directional oscillator, and its size has reached 145mm, compared with some small size units in the past, its sound area is larger, and the sound is more powerful.
So when it is actually used, the effect is really good, especially in some of the strong sense of rhythm, the feeling is very obvious, the overall dynamics are very strong and powerful, the details are also very dense, and the sense of atmosphere is outstanding.
South Carolina Runner CC4 has launched a standard version and a version with memory this time, the version with memory has 4GB storage space, you don't need to link Bluetooth, you can store **can be independent**, it will be more practical in some scenarios, such as going out for two laps temporarily without a mobile phone. The price difference between the standard version and the memory version is not large, and it is recommended that you give priority to the memory version.
In the past, we used bone conduction headphones, if the volume is a little smaller, people next to them can hear the vibration buzzing sound, if the volume is turned on, others can sometimes hear the content from our headphones very clearly, for such a sound leakage problem, Nanka has its own solution, that is, Nanka independent research and development of OT closed sound leakage prevention technology 30. First of all, the special design of the cavity adopts a high degree of sealing to avoid the resonance of the shell, and secondly, the direction of vibration propagation is changed, so that the vibration directivity is transmitted into the human body, so as to achieve excellent anti-leakage effect.
It is relatively common to use bone conduction headphones when riding outdoors, and for calls, Runner CC4 has also been fully optimized, and it has a built-in intelligent call noise cancellation system, all in all, it can eliminate the interference of ambient sound on the reception, so that the opposite side can hear your voice clearly.
What people didn't expect is that the weight of the Runner CC4 machine is only 25g, which is light and fluttering, after all, many bone conduction headset frames in South Carolina are made of titanium alloy, which has good weight control, and also takes into account the strength of the whole machine. Bone conduction itself is worn by the pinna, just like the earhooks of some wired headphones, so the wearing is close to insensibility.
Experience summary: Nanka is one of the earliest brands to do bone conduction Bluetooth headsets in China, after these years of development, its product line is rich, and it is familiar with various technologies of bone conduction, and the price has always been the advantage of Nanka, compared with other similar products on the market, even under a limited budget, Nanka can also give a comprehensive configuration and a good experience, runner CC4 is a very good example.
