When it comes to the choice of sports headphones, bone conduction headphones are always inseparable. When it comes to bone conduction headphones, there is always a domestic brand that cannot be avoided, that is, a first-line brand that has been deeply involved in bone conduction technology for many years, Nanka!What I share with you today is its latest new product that focuses on cost-effective and lightweight design, South Carolina Runner CC4!
The packaging of the Nank Runner CC4 still has an obvious family style. Monochrome background with a headphone sketch in the middle. It is a simple and atmospheric style!
When we open the package, we can see the body of the earphones. In terms of internal packaging and accessories, although it has shrunk compared to his flagship headphones, it is better to be more economical, and it is also good to save the province. 
From left to right, there are the earbuds, charging cable, sound-isolating earbuds and instructions. 
Although it is taking the economic route, the Nank Runner CC4 still feels quite good in the hand. At 25 grams, it's the lightest bone conduction headphones I've ever touched. Don't underestimate the few grams it comes out of, for friends who exercise for a long time, this is also a kind of "boost"!
CC4 adopts the design language of the Nanka headphone family, which presents a matte texture as a whole, and many small details have new ideas. For example, its sound unit is more rounded, and its logo is more beautifully colored. The headphones' power on/off, volume adjustment, sound hole, and magnetic charging interface are all concentrated on the right side of the Nank Runner CC4. This is also in line with the operating Xi of most friends. 
Although some friends often joke that bone conduction headphones are just a sound. This sentence may not have been wrong a few years ago, but now from this point of view, it is somewhat biased. Although it is an economic route, the sound quality of the South Carolina Runner CC4 is indeed good with the blessing of "Ring" technology!Although it cannot achieve the effect of entering the ear, it is still a stable first echelon in terms of bone conduction at the same price. 
The South Carolina Nank Runner CC4 adopted 14The 5mm oscillator is oversized, so its sound quality is also better. When listening to Cai Qin's "Ferry", we can hear that both the vocals and the piano sound have a relatively good restoration, and to a certain extent, we can feel the shock of the low drum sound. 
The same feeling can be obtained in the Eagles' "Hotel California", whether it is the guitar sound of the intro, the cheers of the audience, or the vicissitudes of the singer's voice, it can be displayed relatively well and bring us a sense of immersion. At the same time, when in use, it also does not have the obvious vibration of early bone conduction headphones. 
In addition, it closes the anti-leakage technology during the call, which can also minimize the leakage of the call content. Suffice it to say that in terms of sound quality, the Nank Runner CC4 made me very satisfied!
What's even more interesting is that in addition to the Bluetooth headset function, the Nank Runner CC4 itself also has a built-in 4GB of memory. In the sports that the mobile phone is inconvenient to carry, it still allows you to have enough "** battery life"!As long as we connect it to the computer with a data cable, we can copy the songs as if we were using a USB stick!
Bluetooth 5With the blessing of 3, CC4 also has a faster transfer speed. Even in mobile games like Chicken, we didn't feel any lag at all. At the same time, because it maintains the characteristics of an open ear canal, it is also convenient for us to communicate with our friends.
Light and soft are the tactile characteristics of the Nank Runner CC4, and the one in my hand is khaki with a slightly matte surface and a skin-friendly material, which is quite comfortable to the touch.
It has a seahorse-like design, which is not only cute but also more conforms to the curve of the head. The 15 force zones, coupled with its own light weight, make it almost insensible to wear, and at the same time, it is more suitable for the face and stable to wear.
At the same time, as a headset with sports attributes, the Nank Runner CC4 has also reached the IPX6 waterproof level, whether it is sweating or washing, it can accompany you throughout the process. This is a bone conduction headset that is not high, the use experience is more advanced, and at the same time, it adopts a lightweight design. With the endorsement of Nanka technology, it is not only comfortable to wear, but also adheres to its consistently excellent sound quality. If you also want to choose a cost-effective entry-level bone conduction headset, Nank Runner CC4 is definitely an excellent alternative!
