Enisina Portable Headphone Amplifier,Equalizer HiFi earphone Amp with Audio and USB Cable

As a professional streamer and you tuber its important for me to have great sound quality. This is why I recently changed my headphones to a better set.So, When I obtained this my first thought was to give it a real test. I hooked it up to my PC with my old headphones. I immediately noticed a difference, so I removed this amplifier and tried the headphones without and sure enough there was a lack of quality and a small decrease in volume.After playing with it for a few minutes I worked out that what this does is increase the volume of the sound but without the lack of quality. Often if you turn up your volume you start to lose quality. This obvioulsy means that I can now either turn up my music a little louder or I can turn the volume down and have the level at roughly my normal listening levels.Another great feature is that it charges itself up, so no need to keep changing or charging batteries. Im also told that because it has its own power source that it reduces the power consumption on the device making it ideal for listening to music from your mobile phone or iPod. The reason I dont listen to my music on phone is to save battery life. So, my next test was to try it out. Sure enough Im noticing a big difference on my battery life, its now lasting approx 20% longer than I would expect if I was listening to music.A great little gadget, thats fairly descreet and I shall enjoy using more. What surprised me the most though was the clarity. I expected my music to be louder at a loss of quality, but Im happy to say I was wrong. Im now enjoying better quality, louder music.

This blew the music sounded great at first then just blew on me contacted seller didn't even reply back dont bother cheap for a reason

Just received my portable headphone amp and i gotta say I'm quiet impressed so far. it's a nice compact little amp, its solid but not heavy. It has a metal housing which adds to the quality of it so it feels really durable without any excess weight (which is important when you have kids) With only 40 mins charging you can use it for 5 hours and has a standby time of 200 hours which is pretty cool. I tried it on my laptop external speakers and they have a little amp in them also but I added the mini amp in between the speaker and my laptop to see how it would perform and it caused some distortion at full volume but when its just below it boosted the sounds really well. I was impressed how much it boosted my speaker it actually danced (vibrated) of my table. When attached to headphones (using as it is designed for i guess) it works amazing. I'm not deaf but i have trouble hearing lower noises so low talking in films just muffles no matter how loud I have the volume (too many years listening to overly loud music) and this worked great i could hear everything perfect with more defined sounds/tones. thanks Eryone this is awesome

Bought the product as my sony walkman mp3 player does not have sufficient volume to power my bose headphones, although this amp does not massively boost the volume it does do enough to make the headphones usable and without the walkman at full volume, I would estimate that the volume has increased by about 10 to 20 percent.It has certainly made a difference and has fulfilled my expectations, simple to use, others have said you can not charge at the same time as using it due to the sockets bieng too close together, i have found i can get both in at once but i would not need to, i would normally be away from a power supply when using it.Sound quality is excellent there is certainly no loss of clarity and the bass certainly seems to have improved a little, that may be just as a result of the increased volume, i am no expert.There is no volume control on the unit, it is very small an light and i do not find it cumbersome in use, i normally pop my mp3 player in a pocket when in use and this amp easily fits in as well no problem, as a guide it is about twice the size of a usb memory stick. It has no controls just lights, blue to show its operating, and red when charging, it powers up as soon as you plug in headphones, not when the lead from the amp to your device is plugged in (REMEMBER TO UNPLUG PHONES AFTER USE OR YOU WILL FLATTEN THE BATTERIES) so you can leave it connected to your device but not the phones.If all you need is a little boost to the output volume of your device this should do the trick.Very good value, at this price its certainly worth a try if you need a little volume boost. And the build quality seems good.

Comes with a braided USB for charging and a 3.5mm to 2.5mm to plug in the amp from the phone or device.Has a good and solid feel. However the silver USB looks a little out of place with the black unit and black headphone cable, Although you can not charge and use the device at the same time ( the plugs don't fit in at the same time) and the 2.5mm side of the cable can come out easily cought or pulled.Music can be played substantially louder, at lower volumes has better base while maintaining the higher notes. Hasn't run out of battery in use yet and I've been using it for full days at a time. Over all does as it say on the tin

My main issue is a design flaw the USB power cable and the input socket are too close together meaning the unit cannot be charged while in use.The good news is that yes it does work, and quite well there is a noticeable increase in sound quality.While there is an increase in volume it could be higher I was disappointed with the output volume level.In summary, I will use it but only until I find a better one.

Pros:- small- feels well buildCons- usb port and out port are too near each other so you cannot use it and charge in the same time- device nor manual does not indicate which port is which (in/out)
