Way to bounce back when it’s deformed while storage or usage..

Prepare paper cup or glass cup etc. Pour about 60cc of hot or above 80C water inside of cup. (about 1/3 of paper cup) Dip the deformed XELASTEC inside the water with folding backwards. Throw the hot water after 60~70sec., and pour cold water. Leave in cold water for about 20~30sec., remove the water and let dry in room temperature.

Plastic guide is applied to avoid unexpected deformation or other dust to be stick to products, so secured the easy storage and handling. Please store in the plastic guide if XELASTEC is not in use.

Best tips for secure fit

Easy to clean, but still tacky. Pay attention to the sizing, and be happy with them. No issues with sound.

Sten Murumaa
Really good tips for Sony

These are one of the most unique tips I've ever used, it'll take more than just few hours or days or even weeks to hear/understand etc. the real difference compared to whatever other silicon.

A bit less low resonance (than original Sony foam or silicon), much less outside noise, much better fit after few weeks.

Robert Link
Good Eartips

I found the build quality and fit to be very good.
I have had no issues with my iem's falling out or breaking the seal. I would recommend that you try them.

Cameron Peyer
Amazing Eartips

As far as eartips go, I think this has been my favorite so far. Here's why...

1. Very natural tones and extremely airy presentation
2. Details are not in your face but, if you focus slightly, it is very revealing. I prefer this personally as hearing oversaturated details as it would not be a realistic presentation. Therefore also, no fatigue over long periods.
3. Well fitting, fits slightly worse than some foam eartips such as Tripowin Spirals but has been my best pair for silicone tips.

I am quite pleased overall. 9.25 / 10

Product never received

The package never reached my destination, but from the local agency they gave it as delivered, so I have been trying to solve the problem for more than two months, with about 30 emails between all parties, to continue almost as at the beginning. I think that if I have not received it, and I notify Linsoul, they are the ones who have to collect the receipts and see where the package has been. Do not act as an intermediary between them, and the 3 intermediate agencies that seem to have been used. I have paid them for something I have not received.

Otherwise the product is fantastic. They are the tips that I use in all my IEMs, that's why I had ordered them, but in the end I had to order them elsewhere, and I will think hard about ordering again from Linsoul.


I've tried almost every brand, size, shape, material and these are fantastic. Easiest fit, same isolation as the rest of the ones I tried. Finally found the right ones.

I don't give reviews...

But I will make an exception for these. I have tried dozens of ear tips, but these are the first ones that really work for me, because they stay in my ears., and they are still comfortable and give me a good seal. That is a tall order for my weird ear canals. These are the best. They really work

Great tips

These make a good seal. Sound isolation and comfort are top-notch.

Jon Lau

Fits well and seals well.

Shipping FAQ

Which countries do you ship to?

We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.

We cannot ship to addresses that are "PO boxes or APO/FPO".

*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.

How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*. 

*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.

Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.

Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.

For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments.

  • For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.
