I bought it mainly to use with my IEMs and it actually made a noticeable difference. The sound feels cleaner and has more power compared to my phone’s normal output.
The 7Hz Zero 2 is an absolutely fantastic IEM for the price. The sound is clean, detailed, and well balanced, with punchy bass, clear vocals, and smooth treble. It's my first IEM and i am loving it.
Nice pair of iem’s. A true upgrade for me from 7hz salnotes zero (the OG) Got delivered safely and on time.
Really Recommended as one of the Best DACs. You can also this DAC during Online Calls and Meetings for both on Laptop and Smartphone
One of the Best IEMs with Crisp and Clear Vocals with a Solid Premium Designs
The AUDIOCULAR SPARK Hi-Res Portable DAC Dongle with CX31993 DAC and MAX Amp is a very impressive option for anyone looking to take their mobile audio experience to the next level. Despite its small and portable form factor, it delivers a significant improvement in sound quality compared with the standard audio output found on many smartphones, laptops, and other devices.
The first thing I noticed was the overall improvement in clarity and detail. Music sounds cleaner and more open, with better separation between vocals and instruments. Vocals have a good amount of presence and sound natural, while instruments are easier to distinguish, especially when listening to well-recorded tracks. The bass has good punch and control without overpowering the mids, and the treble provides a nice level of detail without becoming excessively sharp.
The CX31993 DAC does a great job of providing a clean
I’ve been using the AUDIOCULAR D07 CX31993 USB DAC & Amp for a while, and overall I’m quite impressed with what it offers for its size and price. The biggest advantage is its compact and slim design, which makes it very convenient to carry around and use with a laptop, PC, or compatible smartphone.
In terms of sound quality, the D07 provides a noticeable improvement over the built-in audio output of many laptops and phones. The sound feels cleaner and more detailed, with better clarity and separation between instruments. Vocals sound more natural, and there is a good amount of punch and control in the bass without making the overall sound too boomy. It also gives headphones and IEMs a little more power and makes music feel more engaging.
The CX31993-based DAC does a good job of delivering clean audio, and I particularly appreciate the plug-and-play functionality. There’s no complicated setup or additional software required in most cases, which makes it very easy to use. The small form factor is another major plus, especially if you want something portable rather than a bulky desktop DAC/amp.
For casual listening, streaming, gaming, and watching movies, it performs very well. Of course, it shouldn’t be compared with much more expensive dedicated DAC/amp systems, but within its price range, it offers an impressive combination of sound quality, portability, and convenience.
Overall, the AUDIOCULAR D07 CX31993 is a solid choice for anyone looking for an affordable USB DAC & Amp to improve their everyday listening experience. It’s compact, easy to use, and delivers clean and enjoyable sound. Definitely a worthwhile upgrade if you’re currently relying on basic built-in audio.

Loved it
It's actually good piece and getting better sound clarity but not must satisfied with bass even though I bought improved bass version
Comfortable fit. Good for extended listening. Details pop out and treble is clean.
Nice Product, The sound quality is poor when the iem is directly connected to phone but the sound quality is very high when it is connected. Fully satisfied.
Really happy with the Salnotes Zero 2. Sound is clear and bass is good without being too much. Vocals sound nice and the earphones are comfortable even after using them for a few hours. Build quality is also decent for the price. Overall, good IEM and worth the money
