Great product

High quality build with great performance to match. The "loud" function works flawlessly and the three band EQ works perfectly. As a DJ I use the SK01 to fine tune my headphone's frequency curve. I would definitely recommend this product.

Cool piece of hardware

Sometimes Amazon can be like Winners. You get names you’ve never heard of and some are good and some not so much.With this pre-amp from Fossi, I had no idea what I’d be getting. Turns out it’s pretty damn good.I read some reviews about the housing, saying it’s a bit light in the materials/metal used. Maybe those customers had worked for Sherman Tanks, but the material/metal weight is amazing! The construction is heavy-duty, and the metal a very solid thickness.The controls have a nice heavy movement to them, but are smooth, and the buttons have a similar action and a quality feel.The headphone jacks have a quality feel to them, and all around, the item is incredibly solid.The sound quality is amazing, especially for the price. I’ll admit, I was bored and looking at audio accessories when I came across this product. I find Bluetooth headphones can be in the quieter side and wanted something for when you wanted to bring it up to 11. This does it.Overall I’m very pleased and would buy from Fossi again!

Great for music and movies.

I've been using the Fossi portable amp equalizer for a few weeks now. I use it with a pair of Grado 325 open back headphones. This really does enhance the sound .To be able to noticeably increase treble and bass right next go me while using a headphone extension from my receiver is a game changer.Ive had other portable headphone equalizers before but the separation of the mids/bass and treble sounds are very natural sounding with this. I normally can watch a couple of 2 hour plus movies before it needs a charge. You can also use a powerbank to charge while using. I can't recommend this enough, well worth the money.

Well Beyond expectations

Very pleasantly surprised by this amp.I'm using it to drive Beyer DT770 250 ohm headphones from an Audigy FX 5.1 Sound Card on my computer and it's really good! (Yes, I know the sound card will drive hi impedance headphones also but I do a passive split on the output with one side going to an amplifier and the other to this amp so I can control the headphone volume independently of main speakers).I'm very surprised, I thought it would be just another headphone amp that was fairly wishy washy, but it drives 250ohm cans with no problem.No lack of of volume, the punch and clarity is unexpected. Excellent value for money.

Fantastic Product

Was looking for a way to quickly adjust the EQ physically without going through any software, this solves the problem perfectly. Initially bought the Fosi Audio K5 Pro, but returned it due to inadequate performance, this one is way better even though it costs a bit more. Very satisfied with this purchase.
