Review on 🎧 Hifi Portable Headphone Amplifier with 3.5mm Stereo Audio Out, Switch and Dual-Output - Powered by Lithium Battery and 2-Level Boost by Nate Nelson

I don't normally write reviews but this little audio amp really impressed me. I grew up watching music videos on MTV and VH1. Rock, hard rock, heavy metal and alternative rock. Now I rely on YouTube as my main source to watch all of my favorite music videos. The only problem is that I like the quite loud sound. Even with my Koss Porta Pro headphones, I can't get enough of the volume on most of my favorite YouTube music videos. I've tried downloading various sound drivers and possibly updating my sound card, but decided to try one of these little portable rechargeable audio amplifiers and I'm so glad I did! all i could say When I first put it in my headphones and played one of my favorite AC/DC music videos, it was WOW! On the low gain setting it has more volume than I might expect. It lasts up to 15 hours on a charge. The sound quality is crisp and very clear, plus you can use it on any other device that has a 3.5mm headphone jack. .The best $25 I've ever spent. I highly recommend this little amp!
