Bolanle PH400 4-Channel Headphone Amp with 8 Output Ports, 3.5mm & 6.35mm Jacks, Mono/Stereo Switch, 7 Color Breathing Light

I'm always needing just one more headphone amp or something like a D/A with adjustment, which this product does quite nicely. I wasn't expecting a lot, but it looked like a solid build, I liked the controls and layout, and the USB power was a plus. I thought the lighted knobs were a little over the top, but I was ok with them.Once it arrived, however, I was pleasantly surprised as to the quality of the unit. Solid, well laid out, and the audio quality was much better than I expected. The outputs actually push quite a bit of gain, something I sampled with my IEM's to test quality and how much power the outputs would push. I don't have a good set of ear cans to test with at the moment, but given how little gain I had to push compared to some of my other headphone amps, this unit would drive a set of over-the-ear headphones just fine... Probably with headroom to spare. In addition, the output was way cleaner than I expected out of a unit at this price point. The reference material I use to test new headphones and other gear sounded great, with no noticeable deficiencies and a lower-than-expected noise floor.I'll also admit to the fact that I actually really enjoy the 'Breathe' lighting, as cheesy as I thought it might be. They also make an 8-channel version of this unit, and I think I might just end up owning that one, too.Very pleasantly surprised!!!

The media could not be loaded. Very small and compact. Gives you the ability to adjust 4 seperate headphones at once so you don't need invest in a expensive mixer.Works well with budget friendly mixers and live sound cards.Has its own power cablePadded rubber feet for scratch free use

I have a DJ business and I also record voiceovers for money so I purchased this headphone amplifier to be used for DJing, podcasting, and also doing voiceovers with another person.I was using an old Behringer mixer before a friend of mine suggested to incorporate this into my studio. This is a lot smaller and a little easier to use than the mixer. Plus that mixer is 10+ years old.It’s built with steel and looks cool with the LED lights built in.One of the nice features was having both a mini connection and 1/4 inch. I have headphones (Vmoda and Master Dynamics) that require both and sometimes I can’t find the converter for the plug to plug in.The sound quality seems natural with no degradation.For $30 this is a good deal and I anticipate it lasting for 5-10 years.I would recommend to buy this because it’s a solid piece of equipment.

I just needed a multi channel am and not too keen with sound quality but this surprised meThe preamp is cleanLots of clean gainThe design is solidEasy to useAnd the added mono stereo switch is very usefulThe functionality is way over the price pointAnd. Yes it looks good on my desk

Other than a slight hum when no sound is playing, this works very well, and the LED lights are a neat little touch.

I use my headphone amp in my radio studio and after 1 work week of use I really like it. It appears well built out of metal, has nice clicky buttons, and cool led accent lighting. Most importantly it delivers nice sound from our mixer to our hosts headphones and speakers. I recommend!

I compared this to another headphone amp, the Fosi Audio PH04 and this one is far superior at a similar price point. The Fosi degraded the sound Quality significantly. This one sounded just as good as the original audio source if not better. I like that it has both 3.5 mm and the quarter inch input and output jacks. I have various types of monitors and they don’t all have the same plug size so it’s great when you don’t need adapters. The stereo/mono and mute buttons are also handy. The lighted knobs are cool but I’d be fine with just a power light. Very pleased with this purchase!

Maybe I received a bad unit. But the hiss and whine from this is awful. Noise floor is at about 10% volume. I thought with all the positive reviews it would be good, NO! Again, maybe mine was just a bad unit because I can't see all the 5-star reviewers not being able to hear this. I thought maybe it was interference from other equipment, so I systematically checked EVERY other cable, connector, speaker, mic, headphone, IEM, USB device and anything else I could think of but nothing helped. Checked on 2 other PCs in different locations and it was the same. On the plus side it looks great, very good all metal construction. Buttons have nice clicks and knobs are slow and tight. 3.5mm and 6.35mm input/output. But this doesn't help the fact it sounds awful. And it's not even the cheapest 4-channel amp on Amazon.
