LVY Headphone Amplifier A010 Portable Headphone Amp 3.5mm Audio Rechargeable Two-Stage GAIN Switch HiFi Headphone Amplifier Compatible MP3/4, Phones, Computer and Various 3.5mm Audio Digital Devices

My old Sennheiser HD600s were rotting away in a box. Every now and then I'd drag them out, try using them with an iPhone, realize I'd need a dedicated amp to overcome the anemic, pathetic sound quality I was getting, but never got around to researching and buying an amp. Until this one.What a revelation this budget amp is. Tremendous value, compact and nicely built, super easy to set up, charges quickly. I plugged in my Sennheisers and VOILA! - instant magical sound - blows away all my IEMS, and True Wireless earbuds -- EASILY. I'm not an audiophile, but to my ears -- no hiss, can't make out any sort of distortion. Just pure, clean unadulterated wonderful music with enough power to blow out an eardrum or two. Only regret is not finding this earlier.the one thing that could make this better would be charging via USB-C instead of micro, but not going to complain at this incredible price.

Good, just what was expected by the price paid,

I wear hearing aids and require strong in ear headphones. My T5 Klipsch wired headphones along with this Amplifier work perfectly! I really like the audio quality I get with this small device. It gives me more than enough volume without distorting the sound. I can select between High and Low gain. A single charge last quite a long time. I would highly recommend this product to anyone hearing impaired or anyone who just wants more power without the loss of quality High Fidelity.

I had the higher power version of this and it sounded ok, but the connectors failed quickly.This one is just bad, the bass clips no matter what the volume.Save your money for something better.

when plugged in to charge it make a humming noise when charging other then that is good , i would like to get a replacement if possible..
