Latest User Reviews
Great
A perfect product. Exactly as youâd imagine it is
Broke rapidly
After two uses, only one channel keeps working, which is quite useless.
Ampli Casque correct pour un Home studio.
Cet ampli casque fait le job pour une utilisation en home studio.
Les boutons de volume pour chaque sortie casque sont les bienvenues et utiles.
Le son est assez fidèle à la sortie casque de mon interface.
Seul bémol : Absence de bouton on/off.
Does It's Job
Does as promised. Useful addition to your setup if your audio interface doesn't have an integrated headphone amp. Would recommend.
Perfectly adequate
It's pretty bare bones, but it does what I need it to do. It doesn't seem especially sturdy but I don't move it, so that's no big deal.
Perfect and handy!
Nice sound and build quality and easy to use in a small studio!
Love it
Fantastic little amp
I love the build quality and the compact size. Excellent product for the price!
Great quality
This is a great quality, great value headphone amp. Perfect for on location recording for multiple musicians.
Useful headphone amp
The price is great! When you crank the volume up its a little bit noisy, use it on half .Use TRS or RCA!! its very cheap and useful!
Great for Home Studio
Recording and you need the mix to send to a couple of headphones. Perfect for the job. It's budget and easy to use. Quality does degenerate so highly would not recommend mixing or application needing high fidelity through this, but perfect for recording and general listening purposes.
