🎧 Fosi Audio N2 Headphone Amplifier: Portable Amp with 3.5MM Gain & Bass Switch for HiFi Earphones - Powered Dual-Output, Compatible with iPhone, iPod, iPad, MP3, and Computers Review

I don't want to disturb my neighbors by listening to movies through my computer speaker system late at night. A clever alternative is to connect my Sony studio headphones to this Fosi amp to enhance the sound coming straight from my computer's output. I also use it with my Yamaha keyboard which doesn't have adequate volume through non-amplified headphones. I chose this brand from Fosi based on many very positive reviews. Now, as a certified buyer, I'll add my two cents. If you are looking for a

Exactly what I was looking for to make listening to streaming music on iPhone or iPad louder! Got the N2 amp and immediately noticed the weight and quality. Unlike most modern cheap and plastic things. It is metal and feels like a quality product. I've tried it with multiple headphones and made each pair sound louder while maintaining the quality and difference in each, which is what I wanted. For example a gain and bass switch so I can control them depending on the music or headphones I'm…

This amp lags noticeably at high volume or when the bass is on. This is a sure sign that the raw power is not enough to drive the headset. Compared to the Schiit Magni the sound quality is terrible, compared to that I can't believe these are the same headphones. No, I'm not talking volume either, at the same volume the Magni has a lot more power and headroom, allowing for extremely deep, fat bass, a wide soundstage and controlled, buttery smooth mids and highs. All these factors sound like…

My Truck Radio I just couldn't get enough volume when playing music on my IPhone. I bought it hoping to change it. These are the enemies that are in high quality sound! What you really need to do is balance the sound between the radio and the amp so your stock speakers don't burn out. The gain and bass switches are excellent and work as I hoped they would. I don't leave the bass on all the time because it's so deep and rich that I worry about my speakers, so I only use it on certain songs and…

Compared to what else is available in this price range I would give it 5 stars but I would like more bass control. Just the on/off setting doesn't sufficiently account for different headphone types or mastering/sound quality across files, but it's as good or better than anything else in its price range. That said, the N2 does a great job of enriching the sonic presence of pretty much everything I listen to (PC - high-resolution, lossless downloads and streaming - Sonos, Echo Show 8, etc.). The…

This is a great compact amp that's easy to carry. It's light enough and small enough to fit in a pocket, but personally I wouldn't feel comfortable using it for long sessions, especially jogging. I use open-back headphones to listen to my electric guitar while practicing. I have a Fender Mustang Micro Mini headphone amp connected to my guitar and am routing the output of that amp to his Fosi Audio N2 for added amplification. Fosi allows me to keep my Mustang Micro's volume very low to save…

I have been making high-end home audio equipment for 40 years. Bought this amp for outdoor use. One reason for this is the OPA 1642 class D amplifier. This is a Burr-Brown design. Burr-Brown is well known in audiophile circles for its chips. This particular amplifier is used in both professional audio equipment and more expensive Blu-ray players. This amp will make any headphone wake up and sound better. I wanted to go further and use more complex results. I tested with old Sony MDR EX71…
