Review on Neoteck Portable 3.5Mm Headphone Amplifier With Bluetooth 5.0 Receiver, Two-Stage Gain Switch, 16-150 Ohm HiFi Earphone Amp, Aluminum Matte Surface by Marcos Olvera

Great device! Bought specifically to use on my Honda Goldwing because of the amp and Bluetooth capabilites. You can also still use the 3.5 jack but it will override the Bluetooth connection. It added about 15dB to my stock stero system. Couldn't push it to 100% because distortion starts to kick in. I have a noise loop isolator pluged inline to my bike's aux and this device so that should knock out any power noise when running this while charging.Did not hear any power noise while running this on my bike at any RPM. I also have a 2 port USB 12V high speed charger to charge this device and my phone if needed.This device has its own battery so it does not have to be plugged in to run. I don't use this device for anything else so I can't attest to the battery life.Definitely recommend as an inexpensive stereo upgrade option for older Goldwing owners.
