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

I was very surprised by the quality and performance of this amp. Great battery life (easy for a 9 hour work shift, I just charge it after work, don't know how long it will last). Can recommend this amp. I use mine in a two pocket phone case with a Moto g6 and Koss headphones under $20. Just plug in your favorite playlist and set. Heavy metal sounds great on it.

This little gem is perfect for what I wanted. This makes a oommffff iphone needed due to wiems small volume. Music sounds a lot better with it. I use this when flying and am happy again. I have previously purchased the Dragonfly Black and while bulkier it is much better in volume and tone. .Enjoy

I just bought an LG G8 phone with Quad DAC and thought I can't wait to hear it with my new Audio Technica ATH M50x headphones. Well I was very disappointed, my $20 KOSS KPH30iK in-ear headphones sounded better than the M50x as the achievable volume was significantly higher. I thought the problem was with the M50x until I did a little research and realized my G8 didn't have enough power to push them. I bought a cheaper amp with a volume wheel on wheels and it definitely gives my phone extra…

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…

As another reviewer said, don't be fooled by the packaging - a plain white box that says "Enjoy HD shock !" (Obviously the same box is used for HDMI Audio Extractor, HDMI 1x2 Splitter, HDMI 1x3 Splitter, HDMI 3x1 Splitter, etc. But inside you'll soon find a polished, matte black aluminum body with lots of bells and whistles. The connectors include the more typical ones Microphone input and speaker output (6-300 ohms), solid full-range volume control with on/off switch and red LED, second LED to

This was my first headphone amp. I got it to amplify the sound of my Hifiman HE-160 headphones which obviously aren't powerful enough due to the headphone jack on my desktop PC. Also, when I'm in hotels I can't plug my headphones directly into the media box on the back of the TV because the volume is cranking, so I needed a way to control the output. The device appears to be well made with a solid metal body, a long volume knob that fits securely, has no play and is easy to grip, although…

When you read reviews you really want to know "should I buy this?". The short answer is YES, and here's why. The FiiO A3 amp headphone amplifier has been an integral part of my backpack for several years. Since I prefer using power-hungry wired headphones to regular Bluetooth headphones, a headphone amp really is a must-have, otherwise you just end up hearing a mess without getting the most out of your headphones or music. However, a bad headphone amp can be just as bad or worse than no amp at…

When people say "cheap generic Chinese junk" is bad, this little device is the exception I want to point out. I bought this on a whim as I don't like listening to music through headphones and when I plugged my full size Sennheiser headphones into my iPhone it just wasn't loud enough. This little unnamed amp solves that problem and sounds amazing. I bought it two months ago and use it all the time. I can't comment on how long the internal battery lasts as it's always been more than enough and…

Headphone amps are great for driving and reproducing the rich sound in headphones, especially when they are open and high impedance. However, good headphone amplifiers that really enhance the sound instead of just controlling the volume usually cost some money. That was until this amazing device came along. Before this headphone amp, the Fiio amp series was the best and cheapest amp that improved the sound. And as you can see, this amp is very similar to popular amps. However, this amp is made…
