Celebrating its 10-year anniversary, PISLO has introduced its new sub-brand, SullectAudio (诗宇声), aimed at bringing high-end technology to more accessible price points. At the same time, the upcoming SullectAudio H20 flat-head model was first announced during the 11th Guangzhou International Headphone Exhibition in December 2025. For those familiar with Pislo’s reputation, it’s clear that this isn’t just another budget earbud release—in fact, there has never been one to date!

Based on marketing materials posted on Taobao’s listing, the brand is making a bold claim: at its 99 yuan (approx. $14 / €13) price point, the H20 is a “price miracle” born from calculated material costs and large-scale production. They explicitly state their mission is to fight against “cheap electronic waste” by providing genuine Hi-Fi products to the masses.

Unlike many budget brands that outsource production, the H20 is a true “in-house” effort. To guarantee quality, every unit is assembled, tested, and packaged at Sullectaudio’s own factory.

Driver & Tech Highlights

  • Flagship Driver Configuration: dual magnet 15.4mm large dynamic driver with a DLC (Diamond-Like Carbon) dome and a PU suspension edge. This combination provides the rigidity needed for clear treble and the toughness for deep bass.
  • Patented Acoustic Chamber: Includes an embedded metal acoustic flute tube. This design specifically extends low-frequency response, allowing these flat-head earbuds to achieve a “sub-woofer” like depth.
  • Precision Tuning: dual-cavity composite tuning system to ensure a vivid soundstage and clear instrument imaging.

The marketing material does not mention one fact – apparently, there are two versions of these earbuds because the Taoabo listing has more variations to choose when ordering. For instance, there’s “H20B Special Vocal Edition (3.5)” available for almost double the price. Also, there’s also an option of “4.4 High Resistance Version (150 Ohms)” which was not active at the time.

And what about the sound?

SullectAudio claims H20 present a versatile tuning, open soundstage, authoritative male vocals, precise imaging (great for gaming positioning) and movie-like immersion.

Build & Accessories

  • Shells: PVC + metal.
  • Cable: OFC oxygen-free copper + low-resistance braided outer mesh (anti-tangle, durable).
  • Plug options: 3.5mm (gold-plated all-metal splitter), 4.4mm, or Type-C (with 31988 DAC + 972220 op-amp). Type-C variant adds mic + controls (play/pause, next/prev, call answer/end).
  • Includes medical-grade liquid silicone tips.
  • Lightweight: 2.9g per side for “no sensation” wear.
  • L/R indicators on grilles (L/R markings with perforations).

Final thoughts

A few months back we already saw a very similar scenario – Moondrop released the Nice Buds to mark their 10th anniversary. Having tried them, I’d say they sound decent for the money, but nothing more. The build quality, though, felt like something you’d find at a dollar store.

However, the SullectAudio H20 looks much better ‘on paper’ and should be in another league, despite costing almost the same. What we see here are patented acoustic design shells, even more advanced dynamic drivers, higher-quality cables, and medical-grade silicone rings included as a free accessory from Pislo. I will definitely be getting those as soon as they are available on Taobao. Stay tuned!
