Boost your IEM experience with SpinFit's W1 Silicone Ear Tips

The first double-layered and W-shaped core design ear tip
Now available in individual sizes: SS, S, MS, M, and L (Bundled package of S, M, L discontinued)
Similar compatibility with CP145 ear tips

Bloom's Take

Getting the right seal is crucial to getting the best performance and maximum experience with your IEMs. The choice in your tips may seem extremely insignificant, but when your tips are poorly fit, the difference is massive. SpinFit's new W1 silicone tips improve both comfort and stability with their unique core design bumping the soundstage while lowering fatigue. We find them to be a great upgrade from the 145s. The W1 is one of our most popular eartips.

The Design

SpinFit brings the industry's first double-layer WAVE corrugated tube core technology with the W1. They combine two different hardness levels with their inner wave-shaped silicone core, yielding a more stable fit and tip application. The design also improves upon SpinFit's patented annular joint technology with boosted sound reflection and more comfortable fit.

Double-layered Core

The outer portion of the core is softer silicone which lowers fatigue and increase comfort
The inner silicone is harder which provides more stability during installation

W-shaped

Reduces outside pressure
Improves noise isolation

Spinfit W1 Core Benefits

The inner diameter of the ear tip tube is 4.4mm, suitable for IEM bores with a diameter of 5-6mm. They are similar in compatibility to the CP145 tips, but they are slightly larger. SpinFt uses ISO10993 certified medical grade silicone which is zero allergy, high-hygiene, environmentally friendly, and solid elasticity for a clean, comfortable fit.

The W1 Performance

The W1s will provide good extension of extremely high and low frequencies, improved clarity, and rich sound level. You will hear the dynamic details from multiple instruments along with excellent spatial distancing. With a stable, snug fit, you will experience a soundstage not heard before, a deeper, more impressive sound, and you will appreciate your IEMs to their full potential.

Awesome Earbud Tips

I wasn't sure of my earbud tip size so I bought 3 that I thought would fit me, and luckily one was a perfect fit. Usually earbuds always fall off my ear or are uncomfortable but this is the first time I have ever felt comfortable having them in my ears and not fall off! Not only that but the sound just sounds better as well. I'm keeping the others and giving them to friends

If the perfect eartips exist...

It's these! The material is super comfortable. No itching and doesnt get warm. It's a clear tacky silicone texture. The stickiness ensures the seal stays.

In comparison to many other spinfit models this one has an extra sturdy nozzle which is very useful for very heavy iems that need extra strong tips or to extend short nozzles.

I find the bass and treble are well represented but the vocals really pop with these.

A must have tip!

I’ve always liked spinfit’s tips and have the w1 in both small and medium. Because of the price of these tips, you definitely have to figure out your ear size to get the appropriate tip size (they only come in one size). The w1s are very grippy and fit well in the ear. Definitely a must have for a seasoned audiophile, beginners can stick to cheaper tips until they know their size. Would be 5 stars if they were a little cheaper.

Very comfortable to wear has a moderate grip to them as well good for ears that don't produce a lot of ear wax

Great fit, worthwhile purchase.
