Experience The Pure Analog Magic:-

Dual NuTube 6P1 Tubes:-

Developed by KORG and Noritake, the 6th gen NuTube on the iBasso PB5 operates exactly as a conventional triode vacuum tube and creates the same rich and dynamic overtones that are appreciated in a desktop tube amplifier. NuTube achieves substantial power savings with a high-efficiency design. Voltage amplification is also achieved with the NuTube, which results in a captivating and distinctive vacuum tube sound.

High-Efficiency Power Circuit:-

iBasso PB5 adopts a high-efficiency power circuit. The amplifier utilizes six batteries for a robust power supply system. The NuTubes are powered by two batteries while the other 4 batteries provide power to the secondary amplifier. With this high-efficiency circuit, the output is clean and crisp with no audible noise or power interference.

Precise Volume Adjustment:-

iBasso PB5 features extremely diminutive 24-position, 4-section stepped attenuator. It provides optimal analog volume control that greatly enhances the ability to showcase distinctive analog tones and provides excellently precise volume adjustment for both channels.

Tremendously Powerful:-

So cute and so worth it!
Size: 3 Little Kid, Color: Turquoise
AMAZING for my 7 year old daughter. She can tie shoes but I no longer have to wait on her to do so. It takes 2 seconds for her to put these on and she says that they are super comfortable. We have been to Silver dollar City multiple times and she never complains about her feet hurting! They are easily washed in the washer. They hold up great. I think they are very much worth the money! Fit normal.
