Fosi Audio PH04 4 Channel Headphone Amp, Portable Headphones Amplifier Splitter 4 Way for Music Studio, Mixer Audio Sharing Podcast Monitor, Supports 15-150 Ohms with 12V Power Adapter

Seriously one of the best purchases I've ever brought for my gaming setup. If I'm gaming I can play my game audio through my headset and then if I'm editing I can blast it through my speakers at the twist of switch honestly great purchase.

perfect little device

Does the job, has 4 headphones slots and has the 1/4 inch jack I require

As a streamer with my other half, the one problem we had was volume levels that suited us both. We use the Hart Just Mixer for out streams, and it only has 1 headphone out socket for monitoring. This meant that the volume was either just right for him, but too quiet for me or too loud for him and just right for me. This product solves that problem. We take the feed out of the Hart mixer and run it through this device. With independent volume controls for each of the 4 outputs, I can adjust each independently. Another big plus is that this device is mains powered, meaning I don't have to worry about charging it up beforehand like I used to do with our Ekotek amplifier with a splitter. This really is an essential piece of kit for dual streamers in the same room together.

Worked well for a while, then after a few weeks, it began distorting. And now I am unable to use it, pity.

Feels reasonable well made. Quite small. Gives good clear sound. Overall very pleased.

Like the fact that it is working with electricity and not with a battery.

When I turn it on it sounds absolutely horrendous I can barely make out anything, I have tried my headphones on there own and they sound fine, same with the monitors, but as soon as it gets plugged in to the splitter it sounds awful

Fungerar som förväntat

I seldom write reviews but I was stunned and taken aback by this device when I first used it I had to say something. I’m retired so I don’t work for any company even remotely connected to the supply chain of this product. That out of the way I have to say first that I used a Sony MDR-V6 set and a Sony MDR-7506 set of headphones with the Fisk Audio distribution amplifier. The V6 is my favorite set of headphones of which I own 2 pair of and they are the precursor to the 7506 which is the successor to the V6. I own a single pair of the 7506 headphones. By chance I only had one of the V6s plugged into the Fisk distribution amp when I fired up Elton John’s & Dua Lipa’s “Cold, Cold, Heart” to test the Fisk box out and as I stated earlier I was stunned by what I heard. I have never heard such a beautiful reproduction of that song as I did with the V6 plugged into the Fisk!! Oddly I have never heard the V6 sound as good as it did when connected to the Fisk. There was no parametric, graphic, or any other kind of signal boost before or after the Fisk. What I heard was a flat signal simply amplified a tad by the Fisk and it was dare I say it… music to my ears. Very clean. Nothing added. I heard things in the song I’d never heard before. Long story short the Fosi Audio PH04 4 Channel Headphone Amplifier performed well beyond expectations and at a price I believe to be very fair for what you get. Buy with confidence!!!

Loved the product. I have connected my Sony LCD TV with two wireless (IR based) headphones. When both headphones are used together, the volume used to drop, made worse by a lot of interference. After using FOSI, the volumes in both headphones are excellent. And audio interference has disappeared too. Easy to install and use. Highly recommended.

Very nice little amplifier

Utilisé sur ma platine vinyle pour brancher plusieurs casque. C'est pas le top de la qualité mais pour le prix ça fait largement le travail.
