This afternoon, AfterShokz (voice) new media communication meeting was held in Beijing. At the communication meeting, AfterShokz brought their new bone conduction earphones - Aftershokz Bluez2S, which was upgraded based on Bluez2, and the leakage was reduced again. 50%, dustproof and waterproof performance is greatly improved, reaching IP55 level, it is further optimized for ergonomics, strengthening the compatibility of glasses, so that the glasses party wears no pressure.
1. 50% reduction in leakage compared to the previous generation
Unlike traditional earphones, bone conduction earphones transmit sound directly through the tibia to the auditory nerve in a vibrating manner. The user can completely keep the ears open when in use, which brings greater safety, but also has shortcomings through vibration propagation. That is the unavoidable sound leakage phenomenon. AfterShokez has been working hard for generations, the leakage of Bluez 2S has now reached the same level as the original earphone of the iPhone, which greatly enhances the privacy. This can be said to be the pole of the bone conduction earphone. Big breakthrough.
2, waterproof to achieve IP55 level sports headphones is a very important performance indicator is waterproof and sweat-proof performance, although Bluez 2 uses nano-waterproof materials, but in high-intensity sports will still appear by the phenomenon of sweat erosion caused by headphones, Therefore, Bluez 2S fully optimizes the internal waterproof structure to achieve IP55 level, even if it is sweaty, or simply running in the rain will not affect the normal use of the headset.
3, the sound quality is greatly improved because of the vibration broadcast mode, the sound quality of bone conduction headphones has been difficult to achieve the natural level of traditional dynamic headphones, although the demand for sound quality in sports is not very high, but better is always necessary, so AfterShokz development The latest PremiumPitch+ technology, combined with the new EQ settings optimized for bone conduction headphones, has made special compensation for the bone conduction method, the sound quality has been improved, the music is fuller, and the voice call is clearer.
4, shape optimization, more care for wearing glasses users due to the use of rear-mounted wear, for the glasses party will inevitably appear glasses and headphones fight, although Bluez 2 has been optimized for the shape of the glasses, but In the face of the relatively thick glasses legs is still slightly insufficient, because the Bluez 2S further optimized the shape, the thickness of the left and right sides is reduced by 0.8mm, the compatibility of the glasses is better, the wearing comfort is stronger, and AfterShokz is about to target Bluez 2S offers an optional silicone case that is more compatible with all types of cycling glasses.
　 
Bluez 2S is the third generation of the successful UponShokz Bluez series of bone conduction headphones. But in fact it is the fifth generation of bone conduction technology, the previous generation of Bluez 2 won the highest innovation award in the consumer electronics industry in mid-2014. The "Edison Electronic Entertainment Product Gold Award" and the successful entry into Apple's Apple Store official store in the middle of last year, the industry is eye-catching. Globally, Bluez 2 is already the highest technical level of the bone conduction headset industry. With the launch of Bluez 2S, its technology is ahead of similar manufacturers for nearly three generations.
