[15 VDC] So nice sounding and extremely well made. Nothing extra and having the little outputs for consumer headphones is a plus when mixing. Love this thing! 5

[1.4 lb] sturdy, functional. no frills 5

[≥ 90 dB ] This is a great little headphone amp and worth every penny. I use it for remote broadcasts and it is a perfect fit for my application. Five headphones sounds like a lot but we fill it up very quickly. I highly recommend Rolls products. We use Rolls in all of our applications. 5

[16 to 500 Ohms] I use this instead of my stereo for my headphones. You can adjust the volume and it works great when playing my drums. Needs a longer power cord. I would highly recommend this!!! 5

[16 to 500 Ohms] Needed a headphone amp for home studio. This is the only one on the market that handles every impedance from 8 to 1000 ohms-- critical if one is mixing headphone types. Most phones today are 50 to 60 ohm... too low for other amps. Plenty of output channels too. 5

[8 Hours ] way nicer then art and others 5

Keith	07/08/2024
[15 VDC] This works very well to control the volume individually for each of up to 4 separate pairs of headphones all being fed from the same source. 5

[8 Hours ] This little Made in USA amp has a very solid build. It has plenty of power and serves our needs perfectly. We use it in our church media live stream workflow so various team members can monitor the stream audio in real time. Highly recommended. 5

[16 to 500 Ohms] This is probably the best solution for a portable, pro headphone amplifier at the $ price point. What sold me about this unit was its wide range of input configurations and the fact that it does have both size headphone output jacks, which is perfect for working with clients who have their own headphones but not the adapter. These amps have plenty of clean, quiet gain. More than you will need and enough to blow up cans. It doesn't have an input trim so you ought to have some gain control at your source output. Your best bet is to run signal into this thing at unity gain. It is built very well and has a solid, steel chassis. Built in the USA, too.All in all a great piece of equipment that will save the day for only $ 5
