Customer reviews

What listeners say about sound, fit and everyday use.

Write a review

Customers praised the excellent sound quality and powerful amplification. The device features great EQ options, fast interface, and Android compatibility with streaming apps. However, shoppers noted it's heavy, large, and gets warm during use, making it better suited for home use than portability. Some reported battery drain and latency issues when used as USB-DAC.

Big, heavy, built like a tank and sounding great !

This is not a DAP for those looking for a lightweight ultra endurant (battery wise) player. It's heavy, it's mostly made of metal, it gets warm and use some battery with its class A amplification. But you get what you are paying for : super clean sound, an Android interface with some nice Hiby customization & some stylish look.

reply to Linsoul

Because I can't reply to the comment Linsoul posted under my review:

Linsoul isn't telling the whole story.
Yes, they provided a shipping label, but instructed me to make a false declaration whilst shipping. In my country that would be a criminal offense & I would risk losing the money because the shipping insurance does not cover shipping if a €300 product is stated with a value of €30.

Therefore: don't buy from Linsoul.

Hi there,

Thank you for your feedback.

At the time, our suggestion for a lower declaration was intended to help you avoid high customs fees. Please understand that taxes and duties are generally the responsibility of the buyer, and our recommendation was made solely to help save you additional expenses, not to conceal information or encourage any violation.

We apologize if this has caused you any inconvenience.

Your understanding is greatly appreciated!

Don't buy from Linsoul

Linsoul support sucs and isn't Serious in any way. I won't ever buy again from Linsoul.

I got an r4 somewhere else and it's great. Because it's not broken like the one I got from Linsoul.

Dear customer,

We were truly sorry to learn that your HiBy R4 purchase did not meet your expectations and caused you inconvenience—this is never the experience we want for our customers, and we take your feedback seriously.

First, we would like to clarify that we have never taken your case lightly. Upon understanding the issue you encountered with the HiBy R4, we promptly escalated the matter to the manufacturer. The manufacturer responded that they would need you to send the product back for repair, and in line with our warranty policy, we offered to cover the return shipping cost (as the defect was reported within 7 days of product receipt). We also provided you with a DHL shipping label to facilitate the return process, hoping to resolve the issue for you as quickly as possible.

However, we regret that we have not received any response from you since then, nor have we received the returned package. We fully understand your dissatisfaction with the product issues, but we also hope you can understand that we have our policies, which apply to all customers.

We apologize again for the unpleasant experience we have caused you. Thank you for your understanding!

Fantastic 1st DAP

Plenty of power. I really love the PEQ and PlugIns. Looks wise, it's ok but you get so much for your money. *****

Great DAP for home use

Sound quality is great, interface is fast and snappy, EQ options are wonderful. Build like tank, very solid. But kinda heavy and huge. It suits to use at home, but not on transportation. Also when used as USB-DAC to laptop there's some latency.

Great android player at very decent price

Sound is great and powerfull enough to drive any iem and most over hears. Works great at full resolution with all stream apps I've tried qobuz, tidal, amazon and apple music. Not so good with plexamp, seems limited to 24/48 or symfonium, the unit gets very hot when playing from server.
The unit a bit heavy and thick, not very portable, i prefer smaller players for that purpose. I didn't the strap in the package, it should be included, otherwise what's the point of the huge hole in the player

Before you listen.

Fit, connections and your order.

Your order

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 thetwo-way freightcharges. 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 refundwill 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.

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
