Simgot EW300

The short version

What to know.

Simgot's 2024 budget tribrid pairs a 10 mm dynamic driver with a 6 mm planar and a piezoelectric (PZT) driver in an all-metal, mirror-finished shell, with two swappable tuning nozzles and a ~$69 standard price (plus an 'X HBB' retune and a USB-C 'DSP' version). Reviewers agree on a lot: an excellent CNC build, a deep, sub-bass-focused low end with good texture, a rich and natural midrange (female vocals especially), a wide-but-shallow soundstage, and class-above detail — all at a price nearly everyone calls a bargain. The two nozzles make real changes (silver/red ≈ Simgot's energetic 'Golden 2023'; gold/purple ≈ a warmer 'Harman 2019' gaming tune), and the silver nozzle is the near-universal pick. The arguments are narrow but genuine. The PZT-driven treble splits listeners between 'smooth and non-fatiguing' and 'harsh, metallic, sibilant' — the single most common owner complaint — and how it lands depends heavily on nozzle, volume, tips and source. Bass quantity divides too: most hear it as generous, a minority as light, almost always traceable to a weak source or imperfect seal. A faint metallic timbre, some finish-durability and QC reports, and a taste for a little power round out the caveats.

About this product

The ~$69 tribrid EW300 — a 10 mm dual-chamber ceramic-composite dynamic driver plus a 6 mm planar and a piezoelectric (PZT) driver — with two swappable tuning nozzles (silver / red-ring ≈ Simgot's 'Golden 2023' target; gold / purple-ring ≈ a warmer 'Harman 2019' gaming tuning). Sold in three editions that share the same drivers: the standard analog (3.5 mm), the 'X HBB' collaboration retune, and the 'DSP' version (a USB-C cable with a built-in DAC). Not the single-DD Simgot EW200, nor the EA500 / EA500 LM.

Simgot's EW300 arrived in 2024 as a sub-$80 'tribrid' — a 10 mm dynamic driver paired with a 6 mm planar and a piezoelectric (PZT) driver — wrapped in a mirror-polished, all-metal shell with two swappable tuning nozzles. It quickly became one of the default 'just buy this' all-rounder picks in the crowded under-$100 IEM bracket, and ships in three flavours that share the same drivers: the standard analog set, an X HBB collaboration retune, and a DSP version whose USB-C cable hides a little DAC.

Its reputation is unusually lopsided: near-universal praise for build, bass, midrange and value, and a small set of genuinely contested points clustered right at the top end. Reviewers love it; the arguments are about how the piezo treble lands, how much bass you actually get, and a faint metallic timbre — plenty of agreement to bank, and a couple of real fault lines to map.

A good fit for

  • Budget buyers who want a premium metal build and genuine tuning flexibility under ~$80
  • Listeners who like a warm-of-neutral, mild-U signature with deep sub-bass and lush vocals
  • People happy to roll tips/nozzles (and stuff the included foams) or apply a little EQ to dial in the treble
  • All-rounder and gaming use, including anyone upgrading from an entry set like the EW200 who wants more bass, stage and features

Think twice if

  • You're treble-sensitive and won't tweak nozzle/tips/EQ — the PZT top end can read harsh, metallic or sibilant, especially at higher volume
  • You want guaranteed big bass from any source — quantity is source- and seal-dependent, and a weak jack can leave it sounding thin
  • You prize a perfectly natural timbre (the planar/piezo can add a faint metallic edge)
  • You want the DSP cable to be a genuine upgrade — most find the analog version plus a good source the better buy
  • You need class-leading soundstage depth or reference-neutral tuning straight out of the box

Common ground7

  • Premium all-metal CNC shell with a mirror (or matte-black) finish that punches well above a ~$69 price.
  • A deep, sub-bass-focused low end with good speed and texture — the bass quality is praised even where quantity is debated.
  • A rich, natural midrange, female vocals especially, driven by the planar — the standout for several reviewers.

Points of contention5

  • Treble: 'clean, smooth and non-fatiguing' vs 'harsh, zingy, metallic and sibilant' — the most common owner complaint, driven by the PZT and heavily dependent on nozzle, volume, tips and source.
  • Bass quantity: 'deep and generous' vs 'light/underwhelming' — the minority view is almost always tied to a weak source or imperfect seal (it 'comes to life' on a better DAC).
  • Timbre: natural-enough for most vs an occasional 'metallic/artificial' planar-and-piezo coloration.

Band: opinion spread · Dot: weighted average

The single most-argued axis. Most reviewers hear the planar-plus-piezo top end as clean, smooth and non-fatiguing; a substantial owner minority — and the aggregate's #1 complaint — hears it as harsh, zingy, metallic or sibilant. The split tracks the PZT driver and is heavily moved by nozzle (gold is softer), volume (it gets pokey loud), tips/foam, and source.

Measured

Treble is carried by the 6 mm planar plus a piezoelectric (PZT) driver; listeners localize a hot region roughly in the 10–12 kHz range (a common PZT trait), and community EQ profiles cut around 3–5 kHz, 7.5 kHz and 12 kHz to tame it. The gold nozzle and stuffing the included foam filters both pull the top down.

vs. listeners — The same PZT-driven top end is heard as 'clean and non-fatiguing' by most reviewers (often on the silver nozzle, at moderate volume, with a clean source, or after adding foam) and as 'harsh, zingy, metallic' by a sizeable owner minority — 'harsh treble' is the most common owner complaint in the aggregate. Volume, source, nozzle, tips and the PZT timbre all move it, so there isn't one 'true' treble here.

Where it splits
Clean, smooth and non-fatiguing — no real sharpness or sibilance.60%

“EW300’s treble is clean and crisp. There’s no sharpness or sibilance but it has ample detail and a good amount of openness.”

Prime Audio
Harsh, metallic and sharp — the piezo top end is the weak spot.40%

“The reproduction of cymbals can sound unnatural, exhibiting a tinny and excessively sharp reproduction.”

What to keep in mind 6

  1. This is a read of where the reviews land as of mid-2026, in a budget-IEM bracket that moves fast — rivals like the Truthear Hexa, Letshuoer S08, Simgot EA500 LM and SuperMix 4 come up constantly as cross-shops.

  2. Treble harshness is very setup-dependent: the silver nozzle at moderate volume, foam tips (or stuffing the included foam filters) and a clean source tame it for most — worth dialling in before you judge the top end.
