- 1 Pair SpinFit W1 Silicone Eartips
What makes the W1 so good?
✓ Excellent comfort
- Uses soft medical-grade silicone.
- SpinFit's patented pivoting core lets the tip naturally align with your ear canal.
- Comfortable for long listening sessions.
✓ Secure seal
- The new double W-shaped core grips the IEM nozzle firmly.
- Less chance of the tip slipping off compared to older SpinFit models.
✓ Balanced sound
Instead of dramatically changing your IEM's tuning, the W1 usually:
- improves bass extension (thanks to a better seal),
- keeps mids natural,
- preserves treble detail,
- gives a slightly wider, more open soundstage.
Many listeners describe it as making the sound cleaner rather than bassier.
Isolation
Isolation is better than most standard silicone tips but not as much as memory foam.
Typical ranking:
- 🥇 Foam (Comply) – best isolation
- 🥈 SpinFit W1 – very good
- 🥉 Generic silicone – average
Best for
- Neutral or bright IEMs
- Audiophile listening
- Long listening sessions
- People who struggle to get a proper seal
Possible downsides
- More expensive than regular silicone tips.
- Doesn't fit every IEM (designed for ~5–6 mm nozzles).
- Some people with very narrow ear canals find the stem a little long or the silicone too grippy.

If you're looking for a premium silicone eartip, the SpinFit W1 is one of the safest recommendations. It tends to improve fit and seal without significantly altering your IEM's intended sound signature.
If you tell me which IEM or earbuds you're using (for example, Sennheiser IE 600, FiiO FX17, Sony IER-Z1R, AirPods Pro, etc.), I can also tell you whether the W1 is the best choice or if another tip such as the Divinus Velvet, Azla SednaEarfit, or another SpinFit model would suit it even better.

Due to recent changes in U.S. trade regulations, additional tariffs are being imposed on products manufactured in China and imported into the United States.
