MYPIN Headphone Amplifier, Portable HiFi Headphone Amp 3.5mm Stereo Audio Gain Switch Support Impedance 16-300Ω Headset for MP3/MP4 /Phones/Digital Players/Computers/Xbox one,PS4,PS5 Controller

I exercise which watching video on an ipad with headphones. Given the combination of the max volume of an ipad and a set of headphones with a very long cord, my sound level was difficult to hear over the exercise machine noise. With this USB chargeable headphone amplifier in the line between the headphones and the ipad, I can get excellent sound well over the surrounding background noise with level to spare. This product comes in a strong metal case not some cheap plastic garbage. Its on/off/volume knob is also metal, as I said well designed and built. In all the time I’ve had it I’ve only had to recharge it twice as its seems to have great battery life. It comes with a short approx 4 inch cord to go from the amplifier to the source and has as its output a 1/8 in standard jack. It also comes with a charging cord to mate with the amplifier and a USB end to plug into any standard USB wall charger. I haven’t tried it yet but I’m betting I can also use it on my professional audio portable wireless headsets for use during my professional video productions as sometimes it gets noisy backstage for our crew members and the audio sets could use some extra boost. Because these are so small they can fit in a cameraman’s shirt pocket or real pants pocket and given its metal sitting on it or dropping it wont smash like cheaper plastic products.

I’m a bit of a headphone collector and have many high-fidelity wired headphones that I use mostly for music but have always wanted to use them more for gaming. Running a wired headphone setup from the current generation consoles is a bit of a mess in terms of compatibility and effort involved. This little bad boy changes that. The biggest hurdle for plugging high end wired headphones directly into controllers is they often they just don’t have enough power to drive them. I was skeptical of a $20 device being able to drive something like the Sennheiser HD660S2, HD800 or a planar headphone like the Final Audio D8000 Pro - but I can confirm this thing does just that. The high gain even half way handles them well, and there was no noticeable distortion to my ear. I haven’t had it long enough to talk longevity, but everything works as advertised, and all of the mentioned accessories were included. Build quality / appearance seems better than good enough for a $20 device. Honestly even if I had to buy one of these every year it would be worth it.

I needed an inline audio amplifier to boost line out for an external speaker on my game caller, and this amplifier does the job nicely! It allows me to not only amplify the external speaker, but to balance the sound between the internal and external speaker. It has its own rechargeable battery, and the battery life is more than sufficient for my purposes.

I was getting pretty frustrated trying to watch movies on my tablet while on a plane. The noise of the engines was drowning out the sound in my headphones. Of course, sitting in the area with the engines outside the window doesn't help much. I bought this amp and have used it a couple of times on trips and it has made a huge difference. The battery lasts at least 4 hours. I say at least because I haven't run out the battery on a trip yet but have spent 4 hours watching movies on the tablet without a recharge, but the battery is supposed to last 12-15 hours. You will notice some degradation in the sound quality, but you get use to it pretty quickly and it really isn't bad. In fact, it's better than I was expecting. It's a no-brainer to use and it's small enough to easily handle while sitting in your seat. I would recommend this to anyone who travels on a plane for vacations/business/etc.

I purchased this amp on August 1st. It worked great until it suddenly didn't. At 2.5 months the audio dropped during a meeting. Now the volume knob intermittently cuts the audio signal on or off randomly. You can see it in the attached video. Notice the red led flickering on or off. The amp was only used at work a few times a day to boost video meeting audio and has been treated gently. It has a strong metallic case, but the electronics must be poorly or cheaply manufactured to fail after only 8-10 weeks of light usage.

Working great

It does amplify sound but I often get a bunch of loud cracks in the audio when using I got it just as a gag to see if it even worked, it works sometimes

Good battery life. Works fine . Wear on connectors after repeated 3.5 mm removal.

Good solid device well built and works very well

Llego bien empacado y en excelentes condiciones físicas y de operación, además de traer sus accesorios, lo conecte a un walkman sony y a unos audífonos audiotechnica m50x y me encantó como amplificó el sonido, lo bueno es q el walkman tiene para ecualizar las frecuencias y eso es genial, pero lo conecte vía bluetooh a mi iPhone 13 y se pasó un sonido molesto, yo creo q amplificó la señal que emite el bluetooh, y eso hace molesta la escucha de la música, además el sonido quedó muy plano por el hecho de no tener ecualizador en el iPhone, por lo que no recomiendo se use más que conectados por medio de cable, ya que vía bluetooh se metió un sonido nada agradable, pero funciona bastante bien, recomiendo la compra de este aparato.

Great product

Me funciona perfecto para mi piano digital. El sonido es bastante bueno. Viene con dos cables de audio, uno corto y otro largo.

Very sturdy construction and great sound. Keep your eye on the power though, turn it off after every use and you'll only have to charge it a couple of times a week
