THIEAUDIO

Thieaudio was launched in 2019 as a creative endeavor of Linsoul Audio. The goal of Thieaudio was to serve as a creative platform for gathering the best teams of engineers to inspire revolutionary audio products for audiophiles and professionals alike. For each project, we hand select the most innovative and renowned engineers in his or her field to oversee the design, engineering, and manufacturing of the products. Gathering the momentum from the success of the Thieaudio Phantom planar magnetic headphones, as well as the Voyager, Legacy, and Signature series In-Ear Monitors (IEM’s), we are committed to the continual expansion on the limits of high-fidelity audio. We welcome you to join us and experience excellence in musical performance.

Legacy Series

The Legacy series capitalizes on Thieaudio’s proprietary Nano-Membrane Dynamic Driver to create a high-performance hybrid in-ear monitor. Geared towards the discerning audiophile and music enthusiast, the Legacy series re-envisions the qualities that make up high-fidelity audio to present a unique combination of enjoyable tuning that also excels in technical performance. With each model of our Legacy Series, we hope to reveal a refreshing new perspective on your daily listening experience, immersing you deeper into the music. 

Legacy 4

The Legacy 4 was designed concurrently with the Legacy 5 to provide a unique twist to the lineup. With the beloved budget model, the Legacy 3, and the natural and smooth sound signature of the Legacy 5 in mind, we wanted the Legacy 4 to be a middle ground - both in terms of the tuning and price. Utilizing a completely new in-house 8mm poly-membrane dynamic driver for the low end, the Legacy 4 provides the impactful slam of the Legacy 3 and 5, but with a faster speed and enhanced texture. This new driver, matched with the tried and tested American Knowles ED29689 balanced armature (BA) and intuitive low-mid passive crossover design emphasizes a natural mid-frequency presentation. With a less aggressive crossover design than the Legacy 5, the mids of the Legacy 4 presents a more musical experience that ever so slightly adds a dash of warmth to the overall signature. With the partnership of Bellsing, we have developed a custom dual BA tweeter for the Legacy 4 that perfectly fits the mid BA driver. From the relaxed and smooth treble delivery of the Legacy 5, we have tuned the Legacy 4 to bring more upper treble presence, highlighting upper frequency overtones and details. This tuning and the extremely capable treble extension of our new tweeters brings an even greater level of airiness and shimmer to the mix, making the Legacy 4 an excellent IEM for both professional musicians and music enthusiasts alike. You can trust that the Legacy 4 will provide one of the most natural, accurate, and enjoyable musical experiences among any IEM’s of its class. 

Tuning Switch

The Legacy 4 crossover network is integrated into a 2-switch tuning system that allows the user to define the level of bass and mids. This tuning system means you can find the perfect sound signature no matter your musical preference!

A Completely Redesigned Look

Our team has worked hard to completely update our look! Paired with an OCC 4-core custom cable, you’ll find the Legacy 4 in an all new beautiful storage and travel case. 

Hand Crafted, Test for Quality Assurance

Each Legacy 4 unit is hand crafted, from the medical-grade German resin, to the internal circuitry, all the way to the painting of the faceplate. You can rest assured that your Legacy 4 is both a one of a kind in design and in line with all of our quality check protocols. Every pair is individually tested for left-right channel matching and inspected for defects prior to packaging and shipment. At Thieaudio, quality always comes first.

Extremely interesting

- Build quality 10/10
- Isolation and Noise canceling 10/10
- Soundstage 08/10
- Cable 10/10
- Design & Comfort 10/10

After 60+ days of burn-in I give 10/10 to this In-Ear. The sound of Thieaudio Legacy 4 is very detailed, neutral, clean and pretty well balanced

Great IEM for the price.

The Audio Legacy 4 almost perfect

For the price the build quality and sound reproduction is unmatched. Listening through a Schiit Jotunheim is a pleasure that has not lost its luster.

Great tonality and punch, but narrow soundstage.

I'm coming from legacy 3's, the T2, T2 plus, T4, bl03, ER2XR&SE, ER3XR, ER4XR and a bunch more. I find that the tuning is exactly what I want in an IEM, but the soundstage is somehow lacking compared to my legacy 3. Zeos mentioned this in his review, and I didn't want to believe it, but it's pretty noticeable. I'm really not as disappointed as Z was though. It's a fantastic IEM.

Lacking Bass and soundstage

Bass response is low and soundstaging is almost non-existent even after 200 hours of burn in.

Impressive detail with a light and clean sound. Nice stage and decent imaging. Bass is tight with a nice rumble, but it doesn’t kick hard enough for my tastes.

The Definition of IEM

Extension both ways with great detail and very good timbre. 5 stars for value and a complete reproduction of sound! If you enjoy separation and layering these are sure to please. I feel like any musician could use these on stage and get effortless clarity and would hear each element of the mix distinctly. If you like balanced armature sets but always feel better with the 'Bass Boost's on, these deliver the low end - and it's fast and textured almost as if the DD were a large BA.
These are an upgrade from my ikko OH1 and Tin P1. Bass is not quite as lush and full as ikko OH1 but the treble detail and extension is much better on the Legacy 4. I love the clarity of my P1s but vocals don't always sound natural. To me, the Legacy 4 delivers more pleasing vocals - even if they are just a step back in the mix. I was hoping for a bit wider soundstage but it's still there. I would recommend silicone tips. Experiment with different sizes and nozzle types.
As for the dip switches... leave them down/down (default). For me they seemed to decrease impedance and made them feel overly sensitive to the amplification I was using. I have used a slight midbass (125-300hz) boost with EQ to warm up the vocals and lower mids. Like most BA sets, poor recordings can get a bit shouty in the 3k-6k region but the treble is quite well controlled by the filters and configuration they are using.
For $200 IEMs these are an excellent value! Not too warm... Not too dry... Plenty of detail... Yep!

Not that good.

DD Qaulity = Very good
BA Qaulity = Very poor, Too harsh at high frequency. Texture is unnatural.
Too much hyped.

L3 / L4 / L5 - Your Brief Guide

Just a quick summary of the L3 / L4/ L5 for those on the fence on which iem to get:
L3 - Mid bass slam with solid mids and non-threatening highs. Fun. Affordable.
L4 - Modest but tight sub bass focus with clean mids and crispy highs. Narrower sound stage than L5. More resolving than L3.
L5 - Mid to sub bass focus with warm mids and smooth highs. Wider sound stage than L4, with silkier highs.

Buy the L3 if on a tight budget. Buy the L4 if you prefer sub bass and crispy highs. Buy the L5 if you prefer an overall warmer, smoother tone. I like all three, although for my preference I'd prefer to have the Bass of the L4, with the Mids and Highs of the L5.

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?

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.
