The purpose of this machine is to build a very high-end amp platform with minimal money. Provide headphones with greater output power, better sound field and details, and lower distortion. Compared with some 80-90 yuan amps on the market, there are essential differences in materials, chassis, etc. The price of a single battery is much more expensive, and the Omron protection circuit also requires a relatively high cost. Those low-end amps are not equipped with chargers.
The board comes with a socket, which can easily upgrade various op amps![](https://img.alicdn.com/imgextra/i3/32654382/TB2cPNFajfguuRjSspkXXXchpXa_!!32654382.jpg)
The accessories are charger X1, gold-plated plug and recording cable X1, earphone cable tie X2
The default delivery is black, and silver and white can be remarked

Support charging while using
Adopt 3 batteries overlapping power supply. Do not use those low-cost boost circuits, so that the noise is lower, the sound quality is purer, and the battery life is longer
The following reflects the highlights of the next machine, these highlights are not those advertised to say that the amp is better than the 3-400 amp:
1 Using classic op amp + transistor BUF circuit, using 600MA high current output tube, and working in Class A state, so that the distortion is very low, and the sound quality is warm and delicate
2 With Japanese Omron earphone protection circuit, this is very important. Desktop earphones are equipped with relay protection. Portable earphones with relays. There are no two amps without relays within 500 yuan. If there is a problem with the machine, the amp It will hang up, this is a must-have feature! ! !
3 Using an excellent architecture and high-quality battery, it has a battery life of 16 hours, which is longer than many high-level amps. It does not use some businesses to use low-voltage batteries to boost the sound quality by switching power supplies. The sound quality is naturally much purer.
4 All aluminum alloy chassis, although most of the amps on the market are made of aluminum alloy, our appearance is completely different. The ergonomic design, the knobs will not be exposed, and the portable operation is more assured
5 The default configuration of the high-precision Japanese ALPS potentiometer, the left and right channel error is lower, the input uses audio special tantalum capacitors, and the human voice is very good
6 Use the shielded headphone socket of Foxconn exported to foreign countries, the volume is turned on the maximum and there is no bottom noise
Headphone load range: 16-300 ohms
Frequency response: 10-40KHZ
Signal to noise ratio: > 108dB
Distortion: 0.003%
Battery life: about 16 hours
Size: 57.5X16.5X97.5mm is very small
It is recommended to buy this headset, which can meet the challenge of big brands within 800 yuan.
