Brand New DJ44B/DJ44C -More Compact & Smoother Plug/Unplug

Higher standard of gold plating were applied tothe metal contact points on the customized 4.4 sockets, and in order to better check the plug-in contact of each socket, we specially make the socket shell transparent.

Go Further for Lossless Transmission- A gold-plated copper socket shielding ring was addedto the brand-new DJ44B/ DJ44C, which can block theinterference signal at the socket gaps.For the internal connection wire, we use a mixed conductorof 6N OCC and 6N silver-plated OCC, so as to ensureefficient transmission of signals in this small space.


DD DJ44B/DJ44C could be used for 4.4mm TRRRS balanced cable, for example the cables from brands like Sony, etc.

Find a better one.

This worked for a bit, but it just fell apart after less than 5 hours of usage. It wasn't in a damaging situation or anything but the jack was just really weak or something and bends extremely easily.

The L shaped form factor is also limiting if your other ports are next to your 2.5mm and there isn't a straight option, so consider this when purchasing.

I'd recommend getting something different for this need, though.

Unprofessional and rude customer service

My order did not come in even after 3 months. Linsoul guys have asked me to provide them a certificate from my local post office that they did not receive any product. But Linsoul is not providing me a proof of them sending me the order or a proof that is is being delivered and hence cannot refund. How ridiculous ? Why should my local post office people take the burden of providing any proof ? This is just a planned robbery from Linsoul. I urge people from India to stay away from this site. I found them extremely unprofessional and rude during my exchanges with them via email. I will never buy any chinese products in future. A expensive learning came at a cost. Linsoul ?? maybe it implies Nilsoul

Does the job.

I use the DD HI FI with my Qudelix 5K and my ES100 mk2 and it works good with no problems. I’ve been purchasing 4.4 cables, because my ifi Hipdac uses them. Without this adapter I would have to change cables.DD HI FI has good stuff . Highly recommended.

sturdy and ergonomic, fits my player perfectly. Could not ask for a better adapter.

Great 4.4mm to 3.5mm adapter with no grounding issues at all.

Great 4.4mm to 3.5mm adapter with no grounding issues at all.

An amazingly well built, machined, adapter that has no grounding issues at all going from a balanced 4.4mm to a unbalanced 3.5mm. I normally use it for testing on non balanced amps and for my Quest 2. Worth every penny and highly recommended.

It's funky, but fills a niche.

his was obtained with much help from Linsoul, for the purpose of a review. This was NOT FREE... I paid for this.

I got the 4.4mm socket to 2.5mm jack adapter for two SINGULAR PURPOSES. Yes... the emphasis WAS required.. hah.
These are currently for mucking about with my E1DA Power DAC v2 & Radsone ES100 BT damp (dac amp combo) with my various balanced amps.
Thanks to this little guy I am able to not have to rely on the app or system volume to control the volume of the PDV2 but instead I am not using it like a balanced dac. Albeit with less output than would be optimal.
The same can be said for the use of something like the Radsone ES100, or really any other bluetooth damp. If you like the way the dac section sounds but want to either muck about on another amp or just want to feed a more power balanced amp a balanced signal, well this is the way to do it.

It's a chonky little guy, but it's built incredibly, astonishingly well! I feel like I could toss this into the road under a big-rig and pick it up and start immediately using it... assuming I wasn't unlucky enough to have it land jack side up.. or down.. for that matter.
I digress, this is the purpose I use it for. But if you wanted to connect a 4.4mm terminal from a cable to a portable source or a desktop amp whose only balanced out was oddly 2.5mm, well then yer in luck.
This does the job perfectly.
These folks at dd Hifi are cooky, but man they make great stuff so far.

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”

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.
