Pentaconn COREIR Al Alloy Aluminum Eartips for In-Ear Monitor IEM Earphone

The aluminum core prevents the sound conduit from deforming, which helps maintain a consistent, precise shape for the audio to travel through. This design mimics the spatial clarity and depth often found in headphones with metal nozzles, resulting in a more defined soundstage.

These eartips are designed to fit headphone sound nozzles with a diameter between 4.5mm and 5.5mm. Before purchasing, measure the nozzle of your current IEMs to ensure they fall within this range for a secure, slip-on fit.

The COREIR Al eartips come in four sizes: S, MS, M, and L, with maximum diameters ranging from 11.0mm to 14.0mm. If you are unsure of your size, we recommend starting with the size that matches your current, most comfortable eartips, or opting for a size that creates a snug seal without causing pressure in your ear canal.

Yes, the silicone cushioning is color-coded, making it simple to distinguish between the different sizes at a glance. This is particularly helpful if you use different sizes for your left and right ears or own multiple pairs.

Each retail package contains two pairs of eartips of the same size. This allows you to have a spare set on hand or replace both tips on your IEMs simultaneously.
