More Professional Wireless Metronome Solution

Bluetooth audio TWS market is becoming increasingly saturated, product prices continue to go down; lack of R & D capabilities lead to serious homogenization, the product has no characteristics. This triggered thinking about what else Bluetooth can do, how to stand out in many products, get rid of ineffective pay, so that the product value is maximized.

Aggregate analysis of the product found that the current product basically stays in the reference design level, listing parameters, failure to give full play to the chip potential, resulting in a waste of performance. Differentiated applications, deeper digging chip potential, so that the product to do no one else, I have a good.

This program is to innovate in the mature platform through software empowerment and switch to another track. Successfully use the existing audio experience to conquer another group of customers. The solution uses Qualcomm's current main QCC3040 platform, giving full play to the characteristics of fast development cycle, sufficient market inventory and cost advantage brought by mature platforms.

The metronome is widely used in sports and music. It plays a very big role in speed, rhythm mastery. In the Bluetooth headset based on the empowerment of innovation to achieve more advantages than the traditional metronome products.

Compared to the traditional program has the following advantages:

Professional-level sound quality experience

Audio chip platform, professional tuning, stereo output sound crisp recognition rate.

Professional-grade comfortable to wear

Headset shape design, professional adaptation, in-ear, headband, neck a variety of styles customized.

Professional-level timing precision

High-performance processor to bring subtle level of timing accuracy, shooting accurate minutes and seconds.

Professional noise reduction monitoring

Built-in professional DSP algorithm, noise reduction monitoring function all have. Confined environment filtering echoes do not interfere with the open environment monitoring the surrounding area is not missed.

Dual-mode mode, training and entertainment both

One key to switch the beat / headphone mode, training beat, leisure time connected to the phone, a multifunctional portable convenience.
