The media could not be loaded. Amazing performance , I am really very happy with this purchase, Below are some pros and cons -1. Supports 4 headphones in consistent volume on each one.2. High impedance headphones (250 ohms and 600 ohms) support.3. 4 high quality knobs for individual volume control.4. Signal to noise ratio very high , very little noise only if you crank it upto maximum.5. Powerful amplification , medium volumes get the job done most of the times.6. Small form factor and build is very premium for it's price.7. Power adapter cord length is good.Cons.1. No 3.5 mm audio converter provided in the box ( have to purchase separately you'll need atleast 5 )2. Output varies with the input signal volume, more amplification if you provide strong signal , but not a big problem.Rest is all Good , best for it's price probably even better than behringer.

Why I bought?: I have an electric guitar and an Amp (Vox VT40x). So I needed a backing track music to play along. So I bought a Sony walkman (small USB based on) and connected it to the Aux of the Amp. It played well but the Aux volume was low and not matching the guitar sound. I searched and ended up here to buy this Amp for increasing the volume.Result: The volume surely increased but not to what I was expecting. From normal listening I can tell it increased maybe 20%, when I was expecting at least more than 50%. But the audio quality was not good and lot of treble (could be because my Amp is for guitar mid range). So what this device is missing is an EQ settings. I tried my best other ways but couldn't get a satisfying sound. This item is not returnable but only replaceable. So I have no choice. Packed it and kept inside my cupboard.The item looks cool and rugged. My verdict is to get this if you want minor improvement in audio volume and not concerned about EQ settings.

While this is a headphone amplifier, it can also be used to amplify the audio signal coming from cheap Bluetooth audio receivers like the Logitech 980-001276 Bluetooth Audio Receiver with USB.I have the input to this amplifier coming from my Logitech BT audio receiver and the output goes into the AUX input of my sound bar. This way, not only can I get a much better, amplified signal from the BT receiver that's fed into the sound bar but I can also control the volume manually using the volume control knobs.If you're feeling fancy, you could have the same input go into multiple outputs (like a headphone, which is what it's actually meant to be used with. Lol) but I don't need it to do that.Pros:1. Cheap2. Good build quality, solid metal constructionCons:1. Doesn't come with 6.35MM Male to 3.5MM Female adapters. You need to purchase those separately2. No automatic gain control or a gain control knob for the input signal so if your input source (in most cases your PC or smartphone) has low or high volume, you need to manually adjust the output levels on the amp accordingly which does tend to be kinda annoying.

I use this product to connect 2 amplifier and two home theatre with single source. It’s not just produce same output in all ports but also increase loudness with clarity. You can play all at once.. it’s specially give clarity and punchy sound to one of my pa amplifier ..

Amazing product,. Good Sound quality and volume controls. Definitely we can buy this for music production. Value for money. Thanks amazon.
