As an indispensable electronic product in daily life, headphones can be seen in office, travel, study, and entertainment. From common wired headphones, game headphones, to popular sports Bluetooth headphones in recent years, they have different audience groups. Until the release of Airpods, TWS earphones began to lead a new round of trends and technological development.

Prisemi+Trailblazer EDIFIER

The emergence of TWS earphones has not only brought a new round of consumer market, but also prompted major manufacturers to innovate their technology and continuously develop TWS earphones with more functions and more fashionable designs.
As the first professional multimedia audio enterprise in China and the second largest in the world, EDIFIER has been focusing on the research and development of audio technology and product application for 23 years. After entering the TWS field, with its professional audio technology and top-notch industrial and ergonomic design, it quickly attracted countless fans, especially the new NB2 released in May this year, which quickly became a new internet celebrity upon its launch.

Different from the uniform “Apple style” on the market, the unique and technological industrial style appearance not only highlights the appearance of NB2, but also the various black technology functions make its overall quality particularly outstanding.

This new product uses Prisemi’s independently developed overvoltage protection IC to safeguard the charging system of NB2:

In addition, this series of protective ICs supports hard power on with a 25V DC voltage and can withstand individual surges of 40V.

Paired with TVS, it can also handle surge protection level schemes at all levels.

What is even more anticipated is its dual function of overcurrent protection, which has perfectly passed the overcurrent test in EN62368/IEC62368 safety certification. After reaching the overcurrent value, the protection IC is completely turned off.

In addition to the IC, this TWS earphone also uses the Prisemi ultra small package series of protective devices. The miniaturized package can not only meet the performance requirements of TWS earphones, but also save space, reduce costs, and solve the problem of devices not being able to fit.

Wanderer NB2

The Wanderer NB2 adopts a brand new Hybrid composite digital noise reduction, with both internal and external bidirectional microphones accurately capturing noise and eliminating it in reverse, increasing the noise reduction depth by 28% compared to the previous generation. The noise reduction function can eliminate external environmental noise, lower the volume, make the sound quality clearer and smoother, and also provide protection for the human ear. Not only in terms of listening, NB2 also adds microphone noise reduction function, which can maintain stable and clear calls in noisy environments.

It is worth mentioning that the exterior design of the NB2 this time is different from the minimalist business of most wireless earphones on the market. The design of the NB2 is more youthful and personalized, with a strong sense of technology. In addition, this earphone features an ergonomic design, a three-point fixed support structure, and a tilted in ear approach, allowing the earplugs to fit snugly against the earlobe for a more comfortable wearing experience.

Of course, as a headphone, the sound quality of NB2 is also commendable. The high-quality 10MM dynamic driver unit, authentic low-frequency sound effects, and the new generation Bluetooth 5.0 true wireless chip make the sound quality more realistic and three-dimensional, with lower latency.

In terms of battery life, the NB2 also performs exceptionally well, with a built-in battery lasting up to 9 hours and an additional 23 hours provided by the battery pack.

In addition, functions such as quick switching, intelligent breakpoint pause, and waterproofing are also constantly surprising.
