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 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.

Here’s a tip.

Most comfortable tips used to date. Very soft silicone with comfy non irritating fit and a nice balanced sound.

Worthwhile purchase

These buds turned out great, might get another pair.

Not sure how - but awesome!

Being a musician getting blown out by the drums and not hearing my instrument (specifically bass guitar) and vocals, I thought I'd give IEM's a try. I've struggled with sound and fitment from the get go. I had a relatively inexpensive pair ($50) so I upgraded to a $200 pair of Mackies (MP-240), thinking that might help, which shipped with a big variety of ear tips (sizes and materials (both silicon and foam)). Yet only if I hold them, with great pressure into my ears would, I get a good seal where I could clearly hear my bass guitar in the mix. I was convinced my IEM's (along with my transmitter and EQ) were good enough, I just needed a better ear tip.

The W1's were going to be my last attempt at a relatively inexpensive solution (vs custom ear molds). The W1's look exactly like one of the sets I got from Mackie, so I didn't have much hope. I was thinking I'd need something longer to go deeper into my ear.

Yet when I put them in they created an unbelievable seal. I could tell before even plugging in an audio source the isolation from my environment. So far I've only plugged them into my phone, but the sound was incredible! I'll try them plugged into my band's mix this weekend, but based on initial impression, I expect them to perform exactly as I wished. For $10 instead of low end ear molds for $300 (between impression and having them made).

They feel a little sticky to the touch...so I wonder if that has something to do with how they seal. But for $10 a set, I wouldn't care if I had to get a new set every month. I doubt I will, but that would be a small price to pay for the comfort and ability to create a very strong, tight seal!

Thank you!

These are worth every penny!

I just got these in the mailbox today after having done about a one hour session on my drums using the stock ear tips on my Mackie MP 240 IEMs.
I have struggled with fit, seal and cancellation of certain frequencies due to my ear canals not accepting any if the Mackie tip offerings that came with the package. As soon as I put these on, it felt like I had my closed back earphones on again and when I added music and my kit to the mix I was blown away. No chocking of bass or cancelation of highs and not one during one hour of playing did I need to adjust my IEMs, not once sit I hear any outside noise. Our ears are all unique, but it’s good to know Bloom stocks a good deal of Spin Fits offerings, so get the most out of your universal IEM’s with tips that work for you. These are my new go to tips!
