amazon Aune B1 reviews
Aune brand – which is famous for the amplifier used in the price range of $ 200, such as Aune T1, Aune T1 MKII is no stranger. Characterized by the “color” sound of the light, sweet, smooth, attractive Aune has been “attractive” many players while just toddler into the world of audio.
However, before the ascendancy of mobile devices such as smartphones, portable headphones or music players, Chinese manufacturers are forced to “gone with the wind” as the emergence of high-powered audio toys. Recently, Aune B1 – the portable amplifier ClassA was officially launched, the reference price of $200
The first impression on the Aune B1 is the compact design with a modern, beautiful physique. The whole amplifier is made from scratched aluminum monolithic. The front of the Aune B1 is quite unique when it reveals two small windows, through the glass you can see the amplifier circuit inside – quite interesting.
First of all, you need to understand the operating principle of Amplifier Class A – it will activate the whole cycle of the input signal so the output signal is almost constant. Because the amplifier requires constant current, a Class A circuit consumes a lot of power and produces only about 25% of the power.
Although it has a pretty good battery life: 4000 mA, but the Aune B1 only lasts 10 hours of continuous operation (in 20mA mode) and 5 hours (40mA mode). Besides, the amplifier also generates a large amount of heat but the user does not have to worry.
During the experience, when switching to 40 mA currents, the Aune B1 offers a warmer sound, sub bass boosts, sonic field and improved detail. However, this difference is not so much that I could trade 50% of the battery capacity on my device – a truly portable amplifier.
Also, a small note that Aune especially recommends to users: Never switch the voltage from 20mA -> 40mA when the amplifier is active, as it may damage your headset. However, with this “dangerous message”, I think Aune should design this switch more discreet rather than placing the other two buttons.
In fact, when I have not read the manual that has been converted to 40mA, the Fidelio X2 or HD600 is still working normally, but you should not take your headphones to test to avoid the unfortunate circumstances.
With a gain of 15dB and 40mA, the amplifier is capable of pulling up to many high-end headphones fullsize such as the Sennheiser HD600, Sennheiser HD 650, Bebeyerdynamic DT770, Bebeyerdynamic DT880 (250 Ohm) or Audio Technica ATH-R70x. There is the phenomenon of sound, distortion or “singing not sound” of the singer. But there is a problem here, with a capacity of only 25W at 16 Ohm, the Aune B1 will have difficulty with low headphones or in-ear equipped multi-drivers.

In terms of sound quality, the Aune B1 is impressed by the sound and detail, especially the tweaks of the treble range compared to its rivals like the FiiO E12A. The bass is bouncy, fast and tails, the mid is quite cold, dry and the detail is good. Another plus for the Aune B1 is that noisy or hiss does not appear on the background, even for high-sensitivity IEMs.
In short, the Aune B1 fits in with the details-loving ears, the three-band balance, or analytical headphones like the Fidelio X2, the Hifiman HE400 or the Audio-Technica R70x.
Advantage:
+ Beautiful and unique design.
+ Power is strong, can transfer current.
+ Sound detail, clean background sound, significantly improve the sound field.
Disadvantages:
+ Operation is quite hot in 40mA mode (battery life is also reduced considerably)
+ Switches should be designed more specifically for the user to distinguish.
+ Less accessories included
