Review on 🎧 SUCA Audio Tube-T2 Headphone Amplifier: High-Fidelity Mini Vacuum Tube Amp with Low Ground Noise, RCA & 3.5mm AUX Input, Compatible with 6.35mm to 3.5mm Headphone Jack by Christy Grizzle

The product itself is fine, but it has 3 issues that if fixed would turn 3 stars into 5 stars.1. The displays on the device and on the plug are too bright. Why do you need electric lights? When the tubes light up. It's included! 2. Static sometimes in the headphones from the block. Moving the device generates static noise.3. Ssy poor whistles. $39 is a small price for a tube headphone amp, but the tubes should be at least halfway decent. The tubes appear dull and have a rough appearance. Very very cheap. I will replace soon. (The static will likely disappear when the lamps go out). I'm hoping to convert that 3 stars to 5 stars but now the device is $59 instead of the $39 unit.
