The Picks
Best overall: warm-neutral, easy to drive, metal shell. The safe default under $100.
Best for detail: a brighter, more resolving single dynamic driver in a die-cast metal shell.
Best hybrid: 1 dynamic + 3 balanced armatures, warm-neutral. Replaces the Truthear Hexa.
Best around $50: two dynamic drivers tuned to a neutral target, with a bass adapter in the box.
Best new budget set: released early 2026 with more present mids than the original Cadenza.
Best around $20: bright, detailed and wide for the money.
Best cheap neutral set: the Zero:2 adds about 3 dB of bass over the original Zero.
What changed in this update: the original Moondrop Aria and Aria SE, the 7Hz Salnotes Zero and the Truthear Hexa all have newer replacements, so they come off the list (see what replaced them below). The Letshuoer S12 planar moved up to the under-$200 guide as the S12 Ultra.
How these were chosen: amperheads does not own or listen to these IEMs. The list follows the 2026 consensus across seasonal guides (Headphones.com), review aggregators and long-running owner threads on r/headphones and Head-Fi, checked against published specs. Sound descriptions summarise that consensus.

Best Overall: Moondrop Aria 2
See today's price for the Moondrop Aria 2 on Amazon ↗The Aria 2 replaced the original Aria, which (with the Aria SE) earlier versions of this guide recommended. It keeps the single dynamic driver (now with a ceramic-coated dome diaphragm) and the metal shell, at roughly the same $90–100 price. Published specs list 33 Ω and about 122 dB sensitivity, so it runs loud from a phone or a small USB-C adapter.
Reviewers and owners describe a warm-neutral, Harman-style tuning with a slight bass lift and smooth treble: inoffensive, easy to listen to for hours, and good with every genre. That is why it is the default “first good IEM” answer on r/headphones.
Who should not buy it: anyone who wants maximum detail (look at the EA500LM) or heavy bass (look at the S12 Ultra ).
Best for Detail: Simgot EA500LM
See today's price for the Simgot EA500LM on Amazon ↗The EA500LM is a 10 mm single dynamic driver with a lithium-magnesium dome, in a die-cast metal shell. It costs about $90–110. Headphonesty and Headfonics describe it as a step up from the original EA500, with more refined treble and better technical performance.
The tuning leans neutral-bright, so it shows more detail than the Aria 2 at the cost of some warmth. Reviewers note the metal shells are heavier than resin ones, which can matter on long sessions.
Who should not buy it: treble-sensitive listeners and people with small ears.
Best Hybrid: Truthear Pure
See today's price for the Truthear Pure on Amazon ↗The Pure (2025, about $90) is Truthear’s successor to the Hexa. It uses one 10 mm dynamic driver plus three balanced armatures in a 3D-printed resin shell. Reviews describe stronger low end and richer mids than the Hexa, with a warm-neutral overall tilt, and a CreativeBloq piece a year after launch called it the best warm-neutral IEM under $300.
Who should not buy it: anyone looking for a fun, bass-heavy sound. The Pure is tuned to be balanced.
Best Around $50: Truthear x Crinacle Zero:RED
See today's price for the Truthear x Crinacle Zero:RED on Amazon ↗The Zero:RED uses two dynamic drivers, a 10 mm unit for bass and a 7.8 mm unit for mids and treble, tuned to Crinacle’s in-ear target. It sells for around $55. Specs list 17.5 Ω and 117.5 dB/Vrms, and the box includes a 10 Ω impedance adapter that changes the bass. RTINGS and SoundGuys have both reviewed it, and reviewers have treated it as a budget reference for well over a year.
Who should not buy it: anyone who wants a compact shell; the Zero housings are fairly large.
Best New Budget Set: Kiwi Ears Cadenza II
See today's price for the Kiwi Ears Cadenza II on Amazon ↗Released in early 2026 at about $50, the Cadenza II replaces the original Cadenza with a titanium-coated 10 mm dynamic driver and a tougher polycarbonate shell. Reviewers who compared the two found the Cadenza II has more present mids and a sweeter tone, while the original was more V-shaped. Aggregated expert scores are middling, so treat it as a strong gift or first IEM rather than a giant-killer.
Best Around $20: Truthear GATE
See today's price for the Truthear GATE on Amazon ↗The GATE is a 10 mm single dynamic driver at roughly $20 (a version with an in-line mic costs a dollar more). Reviews describe a bright, detailed tuning and a surprisingly wide stage for the price. NextRift found the treble can get hot on busy tracks, and opinions on the bass are split. At this price it makes a great spare pair or gym IEM.
Best Cheap Neutral Set: 7Hz Salnotes Zero:2
See today's price for the 7Hz Salnotes Zero:2 on Amazon ↗The Zero:2 (late 2023, launched at $24.99) is 7Hz’s update of the Salnotes Zero, which an earlier version of this guide recommended. It keeps a 10 mm dynamic driver and 32 Ω, and 7Hz says the low end is boosted about 3 dB. That addresses the most common complaint about the original: not enough bass.
Replaced Models
| Older pick | Replaced by | What to do |
|---|---|---|
| Moondrop Aria / Aria SE | Moondrop Aria 2 | Buy the Aria 2 new; only buy the old one at a clear discount |
| 7Hz Salnotes Zero | 7Hz Zero:2 | Zero:2 |
| Truthear Hexa | Truthear Pure | Pure (some EU shops still sell the Hexa) |
| Letshuoer S12 | Letshuoer S12 Ultra (~$169) | See the under-$200 guide |
If you already own an original Aria, the Moondrop Aria review covers it, and there is no reason to replace a working pair with an Aria 2.
Who Should Not Buy an IEM
- You wear headphones for 6+ hours at a desk. Many people find anything in the ear canal tiring over a full day. An open-back over-ear is often more comfortable; see best headphones under $100 .
- You want the widest stage. Open-back headphones still win there.
- You’ve never found tips that fit. Start with the $20–25 picks to learn your size before spending $100.
IEM vs Over-Ear
Buy IEMs if you commute, travel, work out, or work in an open office. They isolate, they’re portable, and everything here runs from a phone.
Buy over-ears if you listen mostly at home, want a wider stage, or don’t like anything in your ears.
The Cheapest Upgrade: Ear Tips
Tip fit decides bass and isolation more than anything else at this price. If a set sounds thin, try a different tip size or foam tips before you return it. Owners on r/headphones routinely report bigger changes from tips than from a new dongle.
