mobile phone sound quality, FiiO M5

wrote this title, I didn't add a suffix to M5, because it has so many functions that I can't define whether it is a player, a watch or a digital turntable.

find that in recent years, HIFI sound quality mobile phones are rarely seen? Because mobile phone manufacturers put research and development costs on sound quality, the return is far less than the return on cameras, games and other aspects. However, in this scenario, users' demand for sound quality has not decreased, and most mobile phones have canceled the 3.5mm earphone interface. This is followed by a boom in the portable decoding earpiece market and Bluetooth lossless receiving amplifier products.

, the public number has pushed some portable decoding amplifier products aimed at improving the sound quality of mobile phones. They are all wired. They are plugged into the Lightning or Type-c port of the mobile phone. After decoding and amplification, the 3.5mm earphone is output. It is relatively easy to use, but there is still no free wire connection, which cannot meet the needs of the most wireless users.

Bluetooth lossless HD transmission protocol has gradually matured with the passage of time, LDAC, APTX, HWA and so on have emerged.

FiiO is a pioneer in this field. The original ultra-portable BTR1 Bluetooth decoding amplifier was well received once it was launched, and it has been updated to BTR3. The author himself has been using this product, cheap and easy to use, good sound quality and easy to use.

M5 released by FiiO this year can be regarded as the final evolution version of this type of product. Let's talk about it briefly.

is the ultra-small volume of M5, and how small it is is also relatively intuitive-a watch band can be installed and used directly as an electronic watch.

, it has all five internal organs and integrates rich and practical functions. The top is a 3.5mm earphone interface, which supports both LO output and coaxial digital output. The power/lock screen button and volume button are also at the top. At the bottom is a Type-c interface (support storage, audio input, audio output, charging) and TF card slot (maximum support 2T). The front is a touch screen. Yes, it is so simple.

the point is, the reason why M5 is so powerful is mainly two points, the first isTwo-way USB interface supports audio input and output. The other is M5Bluetooth is also supported by two-way input and output. PlusA 3.5mm interface integrating LO, PO and coaxial outputand ultra-small size, so it can be said to be a full-featured, full-interface complete portable audio solution.

M5 is of course very feverish in configuration.The master is Junzheng X1000E, and the decoding chip uses AK4377 of AKM. The maximum specification supports 384kHz-32bit/DSD128, supports almost all lossless music formats, and can hard-work DSD. In addition, Qualcomm's flagship Bluetooth chip CSR8675 supports APTX, SBC, LDAC, etc.almost all common HD Bluetooth audio transmission protocols.

In addition, M5 supports recording. There is also a built-in pedometer, which can use the watch kit to display the time interface.

Let's talk about the M5 usage scenario I personally recommend.

must be the most concerned issue for most users to improve the sound quality of mobile phones. It is not groundless that M5 can improve the sound quality of mobile phones in all aspects.

benefits from the cooperation of flagship Bluetooth chip two-way transmission, USB two-way audio transmission, fever audio decoding chip and amplifier circuit.

improve the sound quality of mobile phones:

1. M5 Bluetooth receives mobile phone audio, and then connects to wired or Bluetooth headset;

2. M5 is connected to mobile phones with USB cable and headphones;

whether wired or Bluetooth, M5 high-specification configuration, improve the sound quality of mobile phones, the effect is very obvious.

motion lossless player:

M5 has a built-in battery that lasts about 13 hours. Install the watch kit, insert the TF memory card to copy the songs into M5, wear it on your hand, and turn into a small sports player. Using wired or wireless headphones, with the pedometer function, the M5 is a good companion for listening to music during exercise.

Bluetooth Receiver for Old Equipment:

Because M5 supports coaxial and LO output, users can use M5 as a Bluetooth receiver for other audio devices. For example, the coaxial output connection decoder of M5 is used, or the LO output of M5 is used to directly connect the active speaker.

In short,M5 covers almost all the functions of wired and wireless-the audio source of turntable decoding, the all-in-one decoding earpiece, the digital turntable, the digital interface receiver, the independent decoder, and the portable player.

is not strong.

briefly talk about sound quality, M5 upholds high-quality sound quality design from the inside out. No matter from pure tone system, file format support, transmission protocol, or in the application of fever chip, audio architecture and high-specification power chip, there are also Hi-Res small gold standard certification,M5 is also certified by Hi-Res.of these are not difficult to see--conservatively speaking, listening with M5 is better than playing on any mobile phone.

M5 completely inherits FiiO's sound view, with no dye, high restoration, and triple-frequency equalization. Although there is no gorgeous color tuning and dyeing of these, but fortunately, listening, not biased, not exciting, clear details, accurate positioning of the image. For all kinds of music styles, inclusiveness is quite strong.

we can't take the sound quality of its PK 10,000 yuan portable player, it is quite the same as that of a 1,000 yuan player.

has achieved a very surprising 598 yuan. I think there is nothing to be picky about the price just by looking at the function.

The above is the content shared calmly today. M5 is a product worthy of attention recently.
