iFiuno - DAC & Headphone AMP - USB-C Input - Improve Lacklustre Audio - Streaming/Gaming/Music Modes Adjust Sound to Suit You - 32-bit/384kHz/DSD256/MQA - Windows/MAC/Smart Device/Active Speakers

I'd purchased a reasonably priced mid-range laptop from Acer - I couldn't justify the cost of a MacBook Pro anymore. Something I wasn't expecting is how poor the sound is (it's and Acer Swift 16, great OLED display as a sidenote ).The Apple MBPs babe decent DACs so you can just plug in headphones and you're good to go, but this Acer is tiny, lifeless and low on volume. Fine for very casual listening but if you're someone used to half decent headphones (Sony MDR-7506, nothing crazy expensive) you'll appreciate the upgrade.There's 2 buttons, the first cycles through the EQ, which is essentially 4 offerings. Off, Game, Video and Music. Really this is highs, mids and lowend boosts. I leave it on music as that's what I prefer.There's a power match button, if you're using in ear monitors or low Ohm headphones that may be enough, easy to play with though.Turning the volume right down turns it off. I've had it for 6 months now and really enjoy it.If you're someone who likes to apply a lot of extra bass, you'll either want to look for something with more EQ controls or use software. I think for most people the subtle EQ options will suit.For the technical side, it supports 32 bit, 384000 Hz. And Hi- Res Audio certified, so if you're using services such as Qobuz or Tidal, you're able to crank the settings. But don't worry, it's an improvement for any source for me. If you're using Windows you will have to change this as the default for the decide is 16bit

I have been using this with two devices. My beyerdynamic dt770 pro and an old Sony HiFi setup. This will adequately power 80ohm headphones when paired with your phone and a USB c cable. It also allows me to connect my phone to a Sony HiFi system that is probably older than me. My phone connects to it via USB c and I can connect to the system either by aux or with RCA as both are supported by the amp. the volume knob is fine adjustable and feels very nice to the touch. When playing music on my phone there is a colour coded light that denotes the quality of music file being played which is a nice touch. The equalizer settings are nice to have although I tend to leave it off. The build quality seems to be pretty good. It has survived multiple drops from a tall shelf with no discernable loss of sound quality. I would say for the price, this will be a good option for anyone looking to get the best out of their headphones or basic sound system and is in my opinion good value for money

Picked this up for a more 'premium' audio solution for my gaming and movies etc on the PC, using it with a set of Audio Technica M50x, and frankly, this is an absolute audio sweet spot for me.. £210 spent, and everything sounds outstanding. Can't fault it at all. Though will say pick up a decent usb-c cable for it.. I grabbed an Anker usb-c to usb-c cable.. The included one is pretty cheap and I actually found my unit had power issues UNTIL I swapped the cable out. Only reason they weren't 5 stars tbh.

Tiny device but very clever sticky pads stop it moving on deskGood sound on the warm side and drive’s difficult headphones very wellWorks with apple with no problems not far off the quality of my Adi 2 dac fs

Love this amp finally my headphones sound perfect out of my pc, great quality no hiss or feedback noise,just loud quality sound.. I would definitely recommend ifi amps.

Was disappointed in the construction quality, very flimsy and the connections were noisy, sent back.

I bought the UNO to use with some existing kit I have. Hooked it up to my MacBook Air and tried it with a vintage Marantz amp I have paired with some Monitor Audio speakers. I tried it with Hi-Res music from both Apple Music and Qobuz. The UNO sounded very impressive indeed.I also have lots of Hi-Res FLAC LPs from HD Tracks, they sounded really good. Whatever I have tried so far it’s always been Hi-Res audio, that’s why I got it. It’s a really good little DAC. I’ve had a few over the years and this has a really nice, clear sound. The sound quality for the price is amazing and it’s a well built little unit. Really Happy and I can breath new life into equipment I already have.

Have been using a Fiio headphone amp for ages but I managed to break it. So looking for a replacement this one seemed to get decent reviews. Plugged it and it all worked OK with Windows 11 recognising it. Really like the no slip pads on the bottom.But the sound... pretty good through Audio Technica headphones. Tried music and games and was really impressed as it just seemed to do its job. The three eq settings are not bad and don't make things bad.Overall, very impressed. The only slight downside is that when plugging in headphones if you have powered speakers attached to the RCA out they don't mute.
