In 2016, everyone was attracted by the modular components of LG G5, especially the LGHiFi Pluswith, which LG cooperated with B&O, attracted the enthusiastic attention of music lovers. In fact, the iPhone can also expand its own functions through OTG. Especially in professional audio peripherals, we can say that there are more professional than G5's HiFi Pluswith. Today's editor will give you a good introduction.

Due to the huge user base of iPhone in the market and the unified data interface, many third-party manufacturers are very happy to develop and produce peripherals for it, and users need not worry about the dilemma that the purchased peripherals cannot be used after the launch of the new iPhone in the future. One of the more representative is the portable headphone amplifier specially launched for iPhone.

Due to the change in the use habits of mobile phone users in recent years, users are accustomed to storing their favorite audio, video and photos on their mobile phones. However, for music enthusiasts, directly using mobile phones to listen to music has always been an obstacle in their minds. Even most of the current HiFi music phones can not achieve what they want because of power consumption and volume problems. At this time, OTG portable headphone amplifier became the only breakthrough. At present, there are many portable headphone amplifiers peripherals specially designed for the iPhone on the market. The iPhone is turned into a turntable in the form of Asynchronous, decoded and amplified by DAC, and then output to the headset. There are many brands and various tuning styles. There is always one that can meet your needs.

Sony PHA-3

As one of the earliest manufacturers of portable earphone amplifiers, Sony PHA series has developed to the third generation: PHA-3。 Its modest body is not only equipped with ES9018 DA converter and TPA6120 headphone amplifier, but also supports balanced output, so that users can clearly hear the sound of each instrument and feel the air. The balanced connection can also significantly increase thrust. The asynchronous transmission mode allows iPhone to decode PCM 384kHz/32 bit format audio or DSD, and its built-in DSEE-HX technology can effectively improve the audio quality of lossy compressed audio sources to close to high resolution audio. Playability is very high, suitable for most enthusiasts.

The connection method is also quite simple. After selecting USB digital audio signal input in INPUT, you can connect iPhone and PHA-3 with a data cable. If you are using 5s or earlier models, you can also use the silicone tape provided with PHA-3 to bind iPhone and PHA-3, which is quite convenient.

Astell&Kern AK10 Portable Phone Decoder

The AK10 should be the smallest portable mobile phone decoder available at present, but its small size does not mean that its material has shrunk. The AK10 is equipped with Ousheng's 8740 DAC decoding chip, which has a very good performance in the processing ability of the highest signal-to-noise ratio and ultra-low distortion. It can decode 24 bit/96kHz audio sources. With its current price of less than 700, it is really a must go product.

The AK10 can instantly transform the iPhone into a lightweight high-quality professional player through the USB DAC function. The connection method is similar to PHA-3. You can connect iPhone and AK10 through a data cable. After connecting iPhone, you can use the dedicated play button on the side of AK10 to press up and down, pause play, and other operations. Moreover, its volume wheel can provide iPhone 135 level volume adjustment to find the most comfortable sound for your ears.

Although the AK10 is slightly less than PHA-3 in terms of stacking materials, the lightweight body and good hardware can provide a good choice for music enthusiasts who like to travel in a light package. With today's cost-effective price, it is very suitable for entry-level barbecuers or light enthusiasts to buy.

ONKYO DAC-HA200 DAC and headphone amplifier

As an old Japanese audio manufacturer, Onkyo also launched its bundled peripherals - DAC-HA200 for the iPhone. Although there is no PHA-3 ferocious in the stack, the price is less than half of it, so it is a cost-effective way. The DAC-HA200 is equipped with a PCM5102 DAC decoding chip, which enables the iPhone to decode 24bit/96kHz PCM or 5.6MHz DSD audio source. The connection with the iPhone is roughly the same as that of PHA-3, both of which have bundled kits. If you need to find a portable DAC and headphone amplifier with balanced sound quality and price, the DAC-HA200 is a good choice.

OPPO HA-2 Portable Headphone Amplifier

OPPO HA-2, as one of the star products of mobile phone decoding earbuds in China, its stacking degree can be described as ferocious, with ESS ES9018-K2M DAC decoding chip, OPA1602 and OPA1662 are two operational amplifiers. The headphone amplifier IC uses TPA6120, supplemented by a current amplifier circuit matched with transistors. It can decode music up to 32bit/384KHz or DSD64, DSD128 and DSD256 when bundled with iPhone. In terms of parameters, HA-2 is more suitable for matching with low resistance earplugs and headphones.

When HA-2 is used as the output of DAC and ear amplifier, in addition to conventional functions such as gain adjustment, it also adds a subwoofer enhancement switch to provide a bass compensation output for moving iron headphones.

As one of the few domestic star products at present, its tone is mild, durable, not eccentric and outstanding, but also has certain quality strength. It can significantly improve the sound quality of mobile phones. In addition, the price of HA-2 is less than 2000 yuan, which is really a very good choice

Through the introduction, do you have a better understanding of the mobile phone decoding ear amplifier peripherals? The portable DACs introduced by Xiao Bian today will have a very good experience when they are used to carry the mainstream high-sensitivity and low resistance earplugs on the market. Among them, Sony's PHA series has always had its unique sound dye. People who love them are dying of love, and people who hate them are dying of hate. The AK10 has a very light volume and weight. ONKYO DAC-HA200 and OPPO HA-2 are relatively pure. The digital flavor is the focus. Of course, there are many small editors that will not be listed one by one. Those who are interested in it can leave a message and discuss it together.

Nowadays, mobile phones are no longer just a multimedia terminal. With the addition of peripherals, they can also become professional equipment in different fields. With the development of technology, the possibility of mobile phones can also be unlimited. I will continue to introduce all kinds of interesting and novel games for you.
