Good idea, Poor execution

I am very sad to say this but TRN BT20S Pro is not a good buy. Unfortunately these have some kind of flaw that makes them create constant white noise and distortion with or without music playing. The distortion fades in getting louder then fades out again. The parts that do work as intended are the play controls, automatic on\off, easy pairing, and the secure fit of the earpiece, however these features are overshadowed by the unwanted distortion.

I do not recommend

The Bluetooth connection is the only positive element. When attached to larger IEMs, the modules sometimes disconnect from the case when closed. The big issue is the left module. The left module has a large amount of hiss that strangely increase with load. The hiss only goes away when there is sound from the full frequency range at an uncomfortable volume. This hiss makes most music unlistenable. The sound from the right side is "good enough". An annoying thin is that the USB C port is moderately deep which make it difficult to use some cables.

Broken out of the box

Got these new & sealed from eBay. Right side came broken out of the box. Does not turn on, does not charge. I'm afraid there is no quality control at all.

Wrong Hook!!!

So I ordered a 0.75mm hook for my trn pro and ordered extra mmcx one. What came is both mmcx! Please refund me the additional money I paid for the extra hook!

Excellent purchase

I got the BT20s pro for work. I work in a steel mill on the rolling floor, lots of noise, but no real need to communicate with others(solo job). I can have music instead of earplugs, but no wires(safety hazard). Using my fiio fa1 with these.

Much better improvement over the BT20s

I’ve had every iteration of the BT20 series and this is by far the best of the bunch by a long shot. It’s more comfortable in the fit with the ear hooks being softer and more pliable. The built in amp drives better at lower volumes (where I’d have to be at 80 to 90 percent volume on the BT20 I only need to be at 40 to 50 on the pro) the charging solution is a million times better and more convenient. I’ve tried the case with a pair of BLON 03s ZS10 pros and Legacy 3s and all of them fit perfectly while connected to the hooks. This changes once you try to add a wire in the case as well but it can still fit if you disconnect the items and sit them flush in the case. They connect pretty much the same as previous versions on first pairing but after that they auto connect as soon as you take them out the case. And the shut off as soon as you put them back in the case. The convenience and improved driving capabilities alone make it worth the upgrade to me.

Only complaint I have at the moment is that you STILL can’t control volume on the headset and having replaceable ear hooks only makes sense if you can buy them separately . It’s not going to give you better sound quality than an es100 or BTR5 but this is for those times that you want better than typical crap TWS sound quality but can’t or don’t want to fiddle with wires of any kind. This is my go to for work listening.

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. 
Please contact us before placing an order, should you have any queries regarding shipping.  

How long does it take to receive the order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • 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.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances

What happens if the parcel has been shipped but not delivered?
  1. First, kindly contact your local courier using the local tracking number.
    If your parcel were to be in transit for at least 3 months, it may have been lost in transit.
    For orders below $50USD, you may either opt for a one-time reshipment of parcel OR a full refund of the amount paid in cash via PayPal/Credit/Debit card.
    For orders above $50USD, we will only process a 50% refund of your order paid in cash via PayPal/Credit/Debit card. Should there be any concern about Standard Shipping, you are encouraged to opt for DHL Express Shipping instead.
  2. Customers are to bear the consequences and fees incurred, if the parcel was undelivered due to any of the following situation:
    • Wrong address or phone number provided by recipient
    • Recipient was uncontactable when courier company contacted
    • Refusal to sign for the package by recipient
    • Lost or damaged parcel because recipient opted for “no-signature delivery”
    • Refusal to pay for the local tax/processing fee by recipient
    • Refusal to provide supporting documents for custom clearance by recipient
Who will pay for the import tax/custom fees

Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.

Should you be unwilling to pay for the fees and reject the delivery of the parcel, you will still have to pay for the shipping cost. Linsoul will only refund the amount of your order after deducting the two-way shipping fees incurred.
