Fosi Audio PH05 5-Channel Headphone Splitter Amplifier, Mini Headphones Amp for Music Studio Mixer, Audio Sharing, Podcast Monitor, Supports 16-300 Ohm High Impedance IEM with 12V Power Adapter

worth every penny !!

Appareil qui aurait pu être parfait si il était adapté aux écouteurs à faible impédances mais ce n'est pas le cas, préparez vous à entendre du background noise avec des iems/casques jusque au moins 30 ohms, snr médiocre, copie à revoir.

I purchased this item by accidentally because I do not have any previous experience about the audio device like this. I have three amplified speakers connected to normal 3.5 jacks 3 pin. I have seen several reviews but none of them give any ideas about how to connect speakers instead of headphones but after connecting speakers with this device I am so delighted the sound quality which is I never expected. The build quality is also superb. Ports and nobs are very smooth. I have DTS audio software incorporated.Thank Fosi audio for making affordable device with good performance.

The product is of high quality, simple to use and the dials provide noiseless altering for required sound level to headphones.

TL;DR: Sound is great. Feels like a solid build. Great for enhancing your private listening. I have generally like Fosi products. I work from home and sometimes need a little music to drown out the world outside so I listen to music through my wired headphones for great sound. I always felt that my iPhone was limited in how the sound came out but it’s always been good enough for my needs. I was curious about this amplifier because never thought I would need something like this. At the price point I thought why not try to enhance my listening experience. Like most novices when it comes to appreciating music, I always felt that the system is only as good as its weakest link. To me that would be the headphones I am using. So that’s why I went with some high-end wired headphones rather than Bluetooth. They sound great, but sometimes I feel like I don’t have enough control over bass treble, and other factors to make this sound even better. This little device actually has a lot of controls to customize your sound. So in my set up, I just use my iPad for the audio signal to put into this device and hooked up my headphones. I have to say that even though I am using an app like Spotify on my iPad, the sound is so much better when I am able to customize the output. The sound is fantastic. I would even say the Bill quality on this thing is solid. Now I am really enjoying my music and even watching movies makes it sound even better as well. I really feel this is a great product and Fosi has done a great job in their designing engineering. I highly recommend this little amp.
