preface

In daily life, some players will install an independent sound card because the integrated sound card on the PC motherboard is ineffective or damaged. Players who take the initiative to replace the independent sound card are generally users with high requirements for sound quality. For mobile phones used in daily life, in order to obtain a higher listening effect, some people will also buy high-end earphones with more than 1000 yuan and some special software. However, due to the different prices, configurations and tuning effects of mobile phones, it is difficult to ensure a better sound quality with high-end headphones or professional software. Similar to PC sound cards, external sound cards for mobile phones have also begun to appear.

Manhuo LYRE 2 mobile phone sound card is a product designed to improve the listening effect of mobile phones. It is compatible with most mainstream Android phones on the market and can be used on Windows, MAC OS and Linux systems. In hardware, multiple professional audio chips and professional peripheral audio circuits are used to process sound, from digital to analog to amplification; The software is combined with the seashell music APP, and the independent audio song decoding library ensures the sound quality output quality. LYRE2 is not only used with mobile phones, but also with some old computers. At present, the sound card of computers has been optimized and upgraded, and the sound quality has also been improved. However, mobile phones are limited by size, and the integration scheme adopted due to price often leads to poor sound quality.

The working principle of the diffuse live LYRE 2 mobile phone sound card is simply an external DAC decoding ear amplifier, which can also be called a sound card. The phone or computer will directly transmit the audio data processed by the CPU to the external LYRE2 through the USB port for processing, without going through the phone audio module for processing. But how about its promotion effect? Gimmick or practical?

Unpacking

The package is simple, including a 156mm long dual head Micro USB data cable and a diffuse LYRE2 mobile phone sound card. The first feeling of LYRE2 in the hand is that it is small, feels good, and has no sense of lightweight plastic. LYRE2 does not have a built-in battery, but gets power from the phone when it is connected to the phone. Therefore, it is necessary to unplug LYRE2 when not in use to avoid continuous power consumption of the phone.

LYRE2 adopts the integrated design of diamond section, with good fit and texture. It is not fixed with screws, so it is a little laborious in disassembly. There are two entity speakers+- adjustment buttons on one side of the fuselage. Press them for 2 seconds at the same time to carry out BassMax low-frequency gain mode. The maximum gain can be 6dB. Press them again at the same time to close.

One end of LYRE2 adopts a 3.5mm headphone jack design, which is compatible with three-level pin earphones and CTIA standard (international standard) wire controlled earphones, and incompatible with OMTP standard (national standard) wire controlled earphones.

At present, most earphones on the market use the CTIA standard. The following is a comparison chart for simple reference.

The other side of LYRE2 is the Micro USB interface used to connect Android phones. If your phone is a TYPE-C interface, you need to buy a new adapter.

Citing official pictures, LYRE2 earphone amplifier chip uses MAX9723 chip, stereo DirectDrive headphone amplifier with BassMax and volume control is used for portable audio applications with high requirements for space and performance, with Maxim noise suppression function, good thrust and low power consumption. The decoding chip uses the PCM2704C, which has the advantage that it can work normally only with the 5V voltage output by the USB without independent power supply. At the same time, as a decoder, it is also a USB audio converter with a very wide range of compatibility. Mobile phones and computers can be connected without driving.

Product experience    

This experience is combined with Meilan 3, Samsung and ASUS Hawkeye mobile phones and APP Haibei music player,

Among the matched devices, except the earphone JVC SX100, SOMIC P6， In addition to Samsung Level ON and Philips, it is also equipped with the rambler S1000 speaker for comparison before and after experience. However, my non professional enthusiasts only made direct and comprehensive comments after audition from their own intuitive feelings and limited cognition, and spent a lot of time on audition and energy on identifying sounds.

In the actual audition, the seashell music player was initially matched, but because the volume was low, a third-party player was replaced to audition local songs such as flac and ape. The player is the default setting, and no gain effect is enabled.

The most intuitive feeling after listening with LYRE2 is that the volume is too low. After turning up the volume, I found that the sound field has become very open and the sound quality has become very mellow.

The high-frequency part shows that the personal sense of resolution is not enough, the separation is average, there is no strong sense of bringing in, but there is no sharp sense, and it sounds soft. For such musical instruments as "High Mountains and Flowing Water" and "Jasmine Blossoms", there is no sense of crispness, but it is more mellow.

The performance of the voice can be said to be the best, because the analysis is relatively full and round, and the articulation is clear. Zhao Peng's "Grandma's Penghu Bay" is relatively stable in performance, without a sense of dullness, and easily and smoothly restores the sound quality; "Moonlight Serenade", a powerful song, not only shows Cai Ma's unique singing skills, but also clearly restores the cricket and frog calls in the background without pressure; It is worth mentioning that the effect of A-Lin's high pitched part in "Thinking of You Live" is very good, free and smooth, without any sense of repression, very extensible, and it feels smooth after singing. Personally, I think pop music or songs such as oratorio perform best.

The low-frequency part of the dive is deeper, the transient performance is better, and it does not bring the sensation of head banging. Take "Sad City", "Drum Poetry" and "Bass King" as examples, the front part of the low part can be easily and freely restored. The dense drumbeats in the second half of Drum Poetry do not have the sense of chaos and tedium, and the separation is also good.

For the regulation of BassMax, I haven't heard any obvious improvement.

Is it effective to improve the film category? yes. Taking Gravity as an example, it can bring you a more shocking audition. The presentation of details is in place, and the performance of different instruments is easy, smooth and natural, which brings a better listening experience while watching.

Experience summary

Lyre2 mobile phone sound card, as a 299 yuan DAC decoding ear amplifier, is mainly used to provide better sound quality. From the actual experience effect, the improvement of sound quality is obvious. It is imperfect but can meet the daily audition needs. It is not a gimmick, but rather practical. In terms of use, it is not only suitable for PCs but also for mobile phones, tablets and other devices, with a wide range of uses. The compact and lightweight volume does not add additional weight, and plug and play is more convenient for use.

If you are not satisfied with the sound quality of the equipment currently in use, but do not want to spend too much money, you can consider LYRE2, but it is better to have a headset.
