Review: Yeah, you won't regret it. - Wired earbuds are my preferred listening mode for just about everything from music to work, to just watching videos. I just picked up some new high impedance IEMs and threw this in the cart on a whim. Holy cow! It felt like I was on a magic carpet singing "a whole new world" duo with Aladdin himself. Total game changer. The gain switch is awesome for lower listening volumes, really gives the sound some punch behind it, but for higher (LOUD) listening volumes, the gain boost can 'muddy-up' the sound a bit if you're listening to bass-heavy music. Super clean sound at high volumes with the gain switch off, though. I cranked this unit for 3+ hours right out of the box before I even charged it. It's got a solid feel to it and I like how the volume knob is just a bit tight, so you can't just accidentally crank on it, volume changes need to be deliberate. The only thing I wish this had was bluetooth, because you otherwise need a janky usb.c-to-trrs adapter or a bluetooth adapter to plug into the input, paired to your phone. (Bt adapter dongle is under $20) I suppose there's probably some higher end DAC units that have bluetooth, but this thing is so awesome for the price, it's worth adding a cheapo BT dongle if you want to use it wirelessly with your phone. I had been using a cheapo bluetooth single-earbud for use with my phone, but it's really only good for podcasts & audio books, the sound quality is ok at best, and I refuse to spend three figures on BT earbuds just to listen to music. This package ended up being about $60-something for IEMs, this DAC (amp), and a $12 BT dongle, and I'm absolutely stoked about it. Top notch sound, this killer amp that seems like it will run all day, and a cheapo BT dongle with similar battery life. It's a do-it-all set up for work or play.
Review: Perfect for me, a powerful in-line amplifier - I bought this to replace an older unit that never delivered very much amplification. Can't say that about the Neoteck unit. It has plenty of power delivering increased amplification to my earbuds, through 15 feet of cable, with a very low volume control setting. I use it to amplify the sound from the Samsung TV with the TV volume completely turned down so that I don't disturb my sleeping wife. The unit works perfectly, and the build is quality and very solid. I especially like having a rechargeable battery to save on battery purchases. With a full charge I watched a 3 hour movie and the unit then recharged in a very short period of time. The sound quality is very good with no distortion or feedback. I am very happy with this device. Update May 2026 The amplifier no longer produces sound for the right ear. Multiple headphones and ear buds have the same problem. I contacted Neoteck customer service four days ago and have not received a response.

### ⭐⭐⭐⭐ Solid little amp. Very Compact
*by J***1 on June 4, 2018*

This is an initial out of the box review done by a pro-audio technician of 40+ yrs experience. That said, It's still IMHO. Received product and charged up. The unit appears well built and the cords are seem very adequate with nice spring strain reliefs. My sound comparsion was done using my new: [OneOdio Adapter-free Closed Back Over-Ear DJ Stereo Monitor Headphones, Professional Studio Monitor & Mixing, Telescopic Arms with Scale, Newest 50mm Neodymium Drivers- Glossy Finsh] For the sound test, I tested using the following broad range of music and sounds; 1. Also sprach Zarathustra, Op. 30-Richard Strauss; Excellent & Accurate. 2.Toccata and Fugue in D Minor, Just like I was there. Nice crisp highs and great low frequency. 3. AC/DC, Thunderstruck & Shoot to Thrill; Oh Yeah..... 4. ABBA Yep, sounds great. 5. Paranoid both GFR and BS versions, No disappointments here either. 6. Lynyrd Skynyrd- Simple Man & Free Bird - Lets face it, it would take an Awfull headphone to ruin these. That said, Front row experience. 7. IRON BUTTERFLY IN- A-GADDA-DA-VIDA, Rock ON!! I evaluated the above without the amplifier and then with. Overall, I am pleased. It does add a more "full body" listening experience. The amplification is clean and quiet. No clipping at high levels (on my headphones). Definately a good purchase for the hearing impaired. They will make good headphones sound better and Studio Grade headphones sound great. THEY WILL NOT make cheapies sound better, just louder. IMPORTANT NOTE; Using these on a headphones with smaller drivers (30mm or less) will overdrive them at higher volume levels. This amp shines best with 40 to 50mm studio grade headphones. I wouldn't spend anymore than I did though. No regrets on what I did spend and do recommend them. EDIT: There are some music selections where the amp will make the BASS sound overdriven. Most noteable is: The Island - My Name is Lincoln Extended. The drums overly BOOM. ALSO; The amp doesn't have "pass through" sound. When the switch is off, kills all sound. Should've been easy to engineer them to do this where if the battery dies, you can still listen barefoot. This is my 1 star deduction,
