BrainQ Technologies Daniel Pepper
Microphone is unusable

The microphone is of very low quality and as such is unusable. The sound quality is ok. The buttons are very hard to press on.

Sefa Eyeoglu
Good quality, bad usability

Sadly this bluetooth module only allows Micro USB. Apart from that I find it regularly sliding around my neck, especially when only one headphone is in my ear. Sound quality wise, these are excellent

Check the hiss noise

check the hiss noise related to my other comment. YouTube video placeholder

Terrible quality

Terrible hiss in the right channel make it impossible to use. It lasted 30 minutes before the noise started. Tried in 3 different cell phones and 2 computers. Stay away.

Thomas W.
Constant terrible hiss and noise.

I am using them in conjunction with the KZN Pro X and have a constant terrible hiss and noise.
Some Bluetooth headsets have that at very low volumes, but in my case it is across the whole range.
I consider it a design flaw.

Byron Melnik
Great addition for my KZ ZS10 Pro's

Bought to use with my KZ ZS10 Pro's in the gym because cables in the gym are annoying. No issues with connectivity (even with older Samsung phones) and sound quality is on par with cables. Battery life on mine is excellent and the build quality is good. Highly recommended!

works good with some downfalls

the bluetooth cable works good for a close distance.
I'm pleased with the high level of sound that it can transfer and the comfortability a bluetooth headset provides.
I also found a few things which could be more optimized -
1. the ear hooks are too big for me and fall out from my ears, I would suggest to make them in defferent sizes
2. the bluetooth doesnt reach to distances longer than 5 meters
3. the buttons are really hard to push and its difficult to work with

Nikolay Gramchev
Very good for the price

Works perfect. Very high value for the price.
Cable is a bit stiff and keeps its own shape.

Nikoloz Japaridze
KZ apt x hd

Works well and connects quickly. If connected to two devices simultaneously (phone and pc), reluctantly switches from one to another. Also, if moved away from the pc, while connected to the phone, it beeps as if searching for another device, Unless switched off and on again the beep remains. Very stiff buttons. Has no function of FFW. Sound transmission is good when on HD. Connection MMCX plug needs bit of a force to plug into earphones

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.
