In normal life, some players will install an independent sound card because the PC motherboard integrated sound card is not effective or damaged. Players who actively take the initiative to replace an independent sound card are generally users who have higher requirements for sound quality. For mobile phones used in daily life, some people will also purchase high-end headsets with more than a thousand yuan and some special software to achieve higher audition performance. However, mobile phones have different prices, different configurations, and different tuning effects. It is difficult to ensure that high-end headphones or professional software can provide better sound quality. Similar to PC sound cards, mobile phone external sound cards also began to appear.

It is compatible with most mainstream Android mobile phones on the market and can be used on Windows , MAC OS and Linux systems. A number of professional audio chips and professional peripheral audio circuits are used on the hardware to process sounds, from digital to analog and then to amplification. The software is combined with Seashell Music APP , and an independent audio song decoding library ensures sound quality output quality. LYRE2 is not only used with mobile phones, but also with some older computers.

Out of the boxThe packaging is simple: a 156mm dual-head Micro USB cable and a live LYRE2 mobile sound card. The first impression of LYRE2 being held in the hand is that it is compact, feels good, and does not have the lightweight feel of plastic. The LYRE2 itself does not have a built-in battery, but instead draws electricity from the mobile phone when connected to a mobile phone. Therefore, when you are not using it, you need to unplug LYRE2 to avoid the continuous consumption of battery power.
LYRE2 uses an integrated design with diamond cuts. It has a good fit and texture, and is not screw-fastened. It takes a lot of effort to disassemble. There are two physical speakers on the side of the body +- adjustment button, press BassMax low-frequency gain mode at the same time press 2 seconds , the maximum gain of 6dB , press again to close.
The LYRE2 is designed with a 3.5mm headphone jack on one end and is compatible with three-pin headphones and CTIA- compliant ( international standard ) wire-controlled headphones. It is not compatible with the OMTP standard ( national standard ) wire-controlled headphones.

Decoder chip is PCM2704C , the advantage is that you can not use independent power supply, only rely on the 5V voltage output from the USB can work normally. At the same time as a decoder is a USB audio converter, a very wide range of compatibility, mobile computers can connect, and do not need to drive.
product experience

In the matching device, in addition to the headphones JVC SX100 , SOMIC P6 , Samsung Level ON and Philips, it also used the Edifier S1000 speaker for comparison before and after the experience. However, their own non-professional enthusiasts only took a comprehensive review of their own intuitive feelings and limited cognition. They spent a great deal of time on audition, and spent a lot of time on sound recognition.
The sea bass music player that started with the actual audition, but because the volume is small, replace it with a third party player to listen to the local flac , ape and other songs. The player is the default setting and does not have any gain effect turned on.
One of the most intuitive feelings of listening with LYRE2 is that the volume is too small. After the volume is turned up, it is found that the sound field becomes very open and the sound quality becomes very mellow.

Zhao Peng’s “Grandma’s Penghu Bay†is relatively stable, has no boring feeling, and has a smooth and smooth sound quality. “The Moonlight Serenade†is a powerful song that expresses Cai’s unique vocal performance in addition to the background sound. The screaming and the frog screaming are clearly restored without any pressure. It is worth mentioning that the effect of the A-Lin treble part of " Live to You" is very good and free and smooth. Any sense of depression, ductility is very good, and it feels smooth down. Individuals feel that the best songs are pop music or cappella songs.
The dive in the low-frequency part is relatively deep, and the transient performance is better. It does not bring about the experience of that kind of explosiveness. Take the example of “The Sad City,†“Drum Poetry,†and “Bass King.†For example, the front-end and low-lying parts can be easily and freely restored. The intensive drums in the second half of Drum Drums did not have the kind of chaotic sensation of depression and the degree of separation was better.
For BassMax 's adjustment, individuals did not hear a significant improvement.
Is there any effect on the improvement of the movie? Have. Taking "gravity" as an example, you can bring more shocking audition to you.
