Most fit complaints with entry-level IEMs come down to three problems, and each one points to a different kind of tip:
- The tips slip out. Look for a tip that follows the angle of your ear canal, or memory foam that expands to grip.
- Bass sounds thin. That usually means a weak seal. Memory foam, or a silicone tip that seals better in your ear, can fix it.
- Pressure or itch on long sessions. A softer, textured silicone tip with a pressure release design is the place to start.
This guide matches five tips from Amazon.com listings to those problems and to three popular IEMs: the Moondrop CHU II, the 7Hz Zero:2 and the KZ ZS10 Pro. It is about picking a tip for your IEM. For the material basics, see our separate foam vs silicone explainer. Every nozzle range below comes from the tip’s listing. We do not give nozzle sizes for the IEMs themselves, so check your IEM’s spec sheet or measure the nozzle before you order.
Still choosing the IEM itself? Our beginner IEM guide and CHU II vs Zero:2 comparison cover that, and the headphone buying guide explains the basics.
Our picks
#1 Final Audio Type E
Best for: Owners who want one kit that covers several nozzle sizes and keeps spare tips organized.
The Type E kit fits earphones with a 4.5mm to 5.5mm nozzle. It also includes a size adapter for IEMs with thinner nozzles, which widens the range of IEMs it can work with. The inner axis is color coded twice: colors change across sizes, and the left and right tips of the same size also differ, so you can tell them apart at a glance.
Final says the tips enhance bass and reduce treble peaks. The kit comes in a hard carry case, which matters more than it sounds if you swap tips between IEMs.
✓ What we like
- Fits 4.5mm to 5.5mm nozzles, with an adapter for thinner nozzles
- Color coded inner axis for size and left or right
- Hard carry case included
- Final says it enhances bass and reduces treble peaks
! Keep in mind
- The adapter covers thinner nozzles only, so nozzles wider than 5.5mm are outside the listed range
- Final’s sound claims are the maker’s own, not measurements we can confirm
Skip it if: You already know your size and only want a single-size refill.

Best for: Listeners whose tips work loose because of their ear canal angle.
The W1 fits nozzle diameters from 5mm to 6mm. Its patented spinnable 3D axis bends to follow the angle of your ear canal, and a double W-shaped tube core is there for stability. The tips are medical-grade silicone.
The listing we checked is size M. SS, S, MS and L are sold as separate listings, so you choose one size per order.
✓ What we like
- Spinnable 3D axis that bends with the ear canal
- Double W-shaped tube core for stability
- Medical-grade silicone
! Keep in mind
- One size per listing, so finding your size can take more than one order
- The 5mm to 6mm range is narrower than the Type E kit with its adapter
Skip it if: Your nozzle is under 5mm, or you want a mixed size kit to experiment with.

Best for: Owners who find their IEM’s treble sharp and want a tip built around that problem.
Spring Tips fit nozzle diameters from 4.8mm to 6.4mm, the widest range at the top end of this list. The nozzle of the tip has an acoustic waveguide, and the body uses a radial double support structure. Moondrop says the design suppresses the treble resonance peak caused by the coupling between the tip and the ear canal.
Each listing is a single size with 3 pairs. The one we checked is size S.
✓ What we like
- Fits 4.8mm to 6.4mm nozzles
- Acoustic waveguide in the tip nozzle
- Radial double support structure
- Moondrop says it suppresses the treble resonance peak
! Keep in mind
- One size per listing (3 pairs)
- The treble claim comes from Moondrop’s own measurements
Skip it if: Your main problem is isolation on a loud commute rather than treble.
🛒 Check price on Amazon↗ Opens Amazon.com · affiliate link, no extra cost to you#4 Comply 500 Core Series Foam
Best for: Travel, noisy commutes and anyone whose silicone tips keep falling out.
Comply’s foam is body-heat activated: it molds to your ear as it warms up. The listing says it grips better than silicone and seals out noise. Each tip has TechDefender sound nozzle protection, which works as a wax guard over the nozzle.
This is the only tip here whose listing names our three IEMs’ families directly: it lists the KZ ZS10 Pro, the Moondrop Aria, Kato and Chu, and the 7Hertz Salnotes Zero as compatible. Comply still says to check its fit tool before buying. The pack covers S, M and L.
✓ What we like
- Memory foam that molds to the ear canal
- TechDefender wax guard
- Listing names KZ ZS10 Pro, Moondrop Chu and 7Hertz Salnotes Zero as compatible
- S, M and L in one pack
! Keep in mind
- Foam wears out and needs replacing, unlike silicone
- Care is limited to warm water and a soft cloth, with no alcohol cleaners
Skip it if: You dislike the feel of foam or want tips that last for years.

Best for: IEMs with thinner nozzles, and listeners bothered by pressure.
The Divinus Velvet tips fit nozzles from 3mm to 5mm, and HiFiGo notes that measurement methods vary. The surface has a matte, micro-embossed coating that HiFiGo compares to velvet. Air escapes through the gaps in that texture, which is how HiFiGo releases pressure in the ear. Five sizes are available. The listing we checked is size L with 3 pairs.
✓ What we like
- Fits 3mm to 5mm nozzles
- Matte, micro-embossed surface
- Pressure release through the texture
- Five sizes available
! Keep in mind
- Built for thinner nozzles, so many wider nozzles will not fit
- One size per listing
Skip it if: Your nozzle is wider than 5mm.

The Type E covers more IEMs. Its 4.5mm to 5.5mm range plus the included adapter for thinner nozzles reaches further than the W1’s 5mm to 6mm range on the narrow end. The kit also comes with a hard case and color coded sizes, while each W1 listing is a single size. If you are not sure of your size yet, the Type E kit is the easier first buy. The W1 makes more sense once you know your size and your problem is tips working loose.
SpinFit W1 vs Moondrop Spring Tips
These two take different approaches. The W1 is about stability: its spinnable axis bends with your ear canal, and its core is built to hold shape. Spring Tips are about treble, with an acoustic waveguide in the nozzle that Moondrop says tames the resonance peak from the tip and ear canal.
On fit, Spring Tips list the wider range (4.8mm to 6.4mm against 5mm to 6mm). Both sell one size per listing, and Moondrop’s comes as 3 pairs. Pick the W1 if tips fall out. Pick Spring Tips if treble is the issue.
Which tip for which IEM
| IEM | If you want more seal/isolation | If you want comfort | If treble feels sharp |
|---|---|---|---|
| Moondrop CHU II | Comply 500 (listing names Moondrop Chu) | Final Type E (kit with adapter) | MOONDROP Spring Tips |
| 7Hz Zero:2 | Comply 500 (listing names Salnotes Zero) | SpinFit W1 (bends with the canal) | MOONDROP Spring Tips |
| KZ ZS10 Pro | Comply 500 (listing names ZS10 Pro) | HiFiGo Divinus Velvet (pressure release) | MOONDROP Spring Tips |
Check nozzle fit before ordering. The Comply listing names these models, and the other tips list nozzle ranges only.
How to choose
- Nozzle diameter. Compare your IEM’s nozzle against the tip’s listed range. Use the spec sheet, or measure it.
- Size packs or kits. A mixed kit is safer if you are guessing. Single-size listings make sense once you know your size.
- Foam lifespan and care. Foam wears out and needs gentle cleaning. Silicone lasts longer and can be washed.
- Wax guard. Comply’s TechDefender covers the nozzle. The CHU II also has a replaceable front filter of its own.
- Different sizes per ear are fine. Many people seal best with a different size in each ear.
Alternatives
Lower-cost or simpler option: Start with the stock tips that came with your IEM, and try every size before buying anything. The CHU II ships with ear tips, and the CHU II DSP ships with S, M and L.
Upgrade option: AZLA SednaEarfit Xelastec, if you want to explore another premium silicone tip after these.
Different need: For travel and noisy commutes, the Comply 500 foam above is the pick for isolation.

FAQ
Do ear tips change the sound of budget IEMs?
They can. The seal affects how much bass you hear, and some tips are designed to change the treble, such as Spring Tips with their acoustic waveguide. Fit is the first thing to get right.
How do I measure my IEM's nozzle?
Check the maker’s spec sheet first. If it is not listed, you can measure the outer diameter of the nozzle with calipers. Compare that number against each tip’s listed range.
Can I use different sizes in each ear?
Yes. Ear canals are often not the same size, so pick whichever size seals and feels right in each ear.
How often should foam tips be replaced?
Replace foam tips once they stop expanding slowly or start to tear. Clean them gently with warm water and a soft cloth, and avoid alcohol cleaners, as Comply advises.
Do SpinFit W1 fit the CHU II?
Check the CHU II’s nozzle size against the W1’s listed 5mm to 6mm range before ordering. We do not list IEM nozzle sizes, so confirm it on the spec sheet or by measuring.
How do I clean silicone tips?
Take the tips off the IEM, wash them in warm water with mild soap, and let them dry fully before putting them back. Avoid alcohol wipes and harsh cleaners. Our guide to cleaning IEMs covers nozzles, foam tips and filters too.
