Fifine Headphone Amplifier 4 Channels Metal Stereo Audio Amplifier,Mini Earphone Splitter with Power Adapter-4x Quarter Inch Balanced TRS Headphones Output and TRS Audio Input for Sound Mixer-N6

I purchased the Fifine Headphone Amplifier and it has been a fantastic addition to my audio setup. The 4-channel stereo audio amplifier is housed in a solid metal body, showcasing its premium build quality right out of the box. The compact design makes it extremely portable and easy to integrate into any audio setup.Setting it up was a breeze. The mini earphone splitter came with a power adapter which made it easy to power up and start using. The 4x Quarter Inch Balanced TRS Headphones Output and TRS Audio Input are perfectly suited for my sound mixer, providing crystal clear audio for my monitoring needs.The individual volume controls for each channel are a godsend, allowing me to tailor the audio levels to my preference without affecting the other channels. This feature came in particularly handy when working with multiple audio sources during a live mixing session.I also appreciate the inclusion of a power adapter which takes the hassle out of finding a compatible power source. The price point is very reasonable considering the build quality and the features it offers.All in all, the Fifine Headphone Amplifier is a reliable and valuable addition to any audio setup, and I would highly recommend it to anyone in need of a versatile headphone amplifier without stretching their budget too much.

This headphone amplifier is perfect for recording engineers on-the-go. Fits easily into a backpack front-pouch. The quality is impressive. It's built tough and has smooth dials. I tried it out with Sennheiser studio headphones and a pair of Beats just for fun, monitoring out from a Focusrite Solo console using Reaper DAW with 25ft extensions. The sound quality was pristine with no latency or distortion issues. Having a headphone amp like this will allow the band to record simultaneous tracks and at the very least, allow the sound engineer to hear what the artist hears. The portability factor alone makes this unit a steal for the price point. You don't have to worry about what to bring to a recording session or loading up heavy rack units anymore. In today's music scene, it's important to be mobile and lightweight. If you're just starting out or on a limited budget, you really can't go wrong with this one. I'm a professional musician with recording experience so I know how important it is to have high quality monitoring over long distances.

I just got this for recording audio internationally. I realized yesterday I was going to need to amp the headphones. This fit the bill, and kept the bill low. It works as expected. The input has no control, so each line get what the input receives. You control the individual headphones independently.What no other review has mentioned is the power adapter. I need this for using internationally, i.e. 240v. The power adapter input is 100-240v. Just what I needed. That spec needs to be added to the item description. I searched high and low and couldn't find it. Maybe all adapters are dual voltage, but knowing for sure would be super helpful.

Clean sound into my headphones are a plus. But I wish there were 3 changes.1. A longer power cord2. Power input opposite side of headphone jacks3. An on/off switchGreat build quality.

I tried cable audio splitters and they did not work because of ground loop issues and noise on one speaker. I tried this little audio amp and could not be happier. I run a line from a Bluetooth receiver (from my smartphone playing MP3 files) to the input. I am currently running 3 channels output, two to powered speakers and one to a Cambridge Radio. I cannot hear any degradation of sound quality. I did not expect an audiophile system performance but it is surprising good and clean on all speakers. I used RCA to 3.5mm jacks and run everything 3.5mm to the inputs of the speakers and radio. This was for my workshop area and it fills the room with sound that is more than acceptable to say the least. The individual channel controls are nice and works as advertised. For the money it is a killer deal and I highly recommend it.

If you are looking for a portable, inexpensive, reliable, easy-to-use headphone amp, this is a great choice. It's smaller than my hand, and the controls and inputs/outputs are simple. With a single stereo input and 4 stereo outputs, the N6 headphone amplifier enables you to connect 4 separate headphones without coloring the sound or any degradation in volume/quality, even at high volume levels. Each headphone channel has a single volume control, for each single user to control his or her output level. The box is made of metal, but the volume controls are plastic. It can be run in stereo or mono.I was able to use this headphone amp in my home studio, and ran some tests on it. I initially just listened to a song, and compared it to the sound coming straight out of my interface device. Then I added headphones to the outputs on the amp. In both of these cases, the sound was unaffected, and sounded the same as it did coming through my interface. Then I recorded a sound wave, and ran that through the headphone amp. I added the other three outputs to the mix, and recorded the sound wave again, with the other outputs connected. The wave form was identical each time.I received this item to test and review.
