ROXA-T1000 is the latest model developed as an upper-tier version of the ROXA-S100.
Compared to previous LOAK series models, it adopts a fundamentally different approach in both structure and materials.
The housing uses Ti-6Al-4V (Grade 5 titanium) for the front, body, and rear.
Unlike earlier models that featured a wooden backplate, the rear section of the ROXA-T1000 is integrated with the body, forming a semi-open housing design.
This structure was chosen to achieve both an open, airy sound and precise control of resonance.
The sound tuning is based on the LOAK2-TX00, a monitor-tuned model that was produced only in very limited quantities for testing purposes.
From this foundation, the ROXA-T1000 has been further refined to deliver enhanced transparency and resolution.
While the sound remains clear and well-defined, it never becomes aggressive; the edges are kept deliberately mild.
Subtle nuances and natural decay are carefully reproduced, resulting in a smooth, comfortable, and musical listening experience.
About the Housing Materials:
The ROXA-T1000 adopts a fundamentally different design from the LOAK2 series and previous ROXA models, both in terms of housing structure and materials.
Front housing: Titanium (Ti-6Al-4V / Grade 5 titanium), CNC machined
Body & rear housing: Titanium (Ti-6Al-4V / Grade 5 titanium), 3D-printed, semi-open design
The housing of the ROXA-T1000 uses Ti-6Al-4V (Grade 5 titanium) for the front, body, and rear, resulting in a fully titanium construction.
In the lower-tier ROXA-S100, stainless steel was used for the front, resin for the body, and wood for the rear.
In contrast, the ROXA-T1000 has been completely redesigned using Grade 5 titanium, a material that offers significantly higher rigidity and strength.
While the LOAK2 series employed pure titanium for the body, Grade 5 titanium surpasses it in both hardness and structural strength.
This increased rigidity suppresses unwanted housing vibrations, enabling faster transient response and a cleaner, more precise sound.
As a result, sound outlines and imaging become more clearly defined, and overall resolution is noticeably improved.
In addition, the driver mounting section of the front housing incorporates a minimal amount of stainless steel to precisely control the vibrations of the dynamic driver.
This targeted use of stainless steel reduces instability in vibration, producing solid, well-defined bass and a stable, focused sound image.
By combining different metals in carefully selected areas, the ROXA-T1000 achieves both high rigidity and effective vibration control, forming a housing structure that supports highly precise and accurate sound reproduction.
About the Housing Design:
The ROXA-T1000 is designed based on the body housing shape of the ROXA-S100.
Compared to the LOAK2 and MIROAK-II, the shape provides firmer support at both the front and rear of the ear, resulting in a more stable and secure fit.
This improved hold reduces movement of the earphones during use, suppressing unnecessary vibrations.
As a result, image instability is further minimized, leading to more consistent and stable sound reproduction.
The angle and position of the cable exit have also been reworked and optimized to create a cleaner, more refined appearance when worn.
This refinement enhances both natural fit and ease of handling, making the earphones comfortable and practical for everyday use.
The rear housing is integrated with the body, forming a semi-open structure.
During the early stages of development, a fully closed design was also considered, and there were plans to release both closed and open versions.
However, by adopting Grade 5 titanium for the body housing, the overall rigidity and stiffness of the structure increased significantly.
As a result, it became clear that a fully closed design would cause excessive air pressure and reflection against the diaphragm.
For this reason, the ROXA-T1000 employs a semi-open structure, allowing excessive air pressure to escape in a controlled manner.
This approach preserves the fast transient response, sharp articulation, and precise imaging characteristic of Grade 5 titanium, while maintaining a well-focused and clearly defined sound.
The integrated body-and-rear semi-open design features a highly complex geometry.
To realize this structure with precision, a 3D printing manufacturing process was selected.
By integrating the body and rear housing into a single structure, the number of components is reduced.
This design choice also contributes to keeping the final price lower compared to the LOAK2 series.
In addition, the semi-open section on the right earpiece is marked with the “634” logo, making left–right identification intuitive.
This is a small but distinctive detail unique to the ROXA-T1000, balancing functionality and design.
About the Sound:
The sound of the ROXA-T1000 is based on the tuning of the LOAK2-TX03 and the TX00 (an unreleased model), and has been further refined to enhance transparency and resolution.
Overall, the presentation is extremely clear and articulate.
Sound outlines are well defined, yet never sharp or aggressive; the edges remain intentionally mild.
Fine nuances and natural decay are reproduced with care, resulting in a sound that remains comfortable and non-fatiguing even during long listening sessions.
Rather than emphasizing any specific frequency range, the ROXA-T1000 maintains a natural connection from bass to treble, forming a highly balanced and coherent sound image.
Within its open and spacious soundstage, the sound carries rich resonance, tonal depth, and a refined sense of luster, spreading naturally and comfortably.
This tuning achieves a high-level balance between delicacy, clarity, and listening comfort, representing one of the most complete and musically elegant sound signatures in the ROXA lineup.
In addition, unlike previous 634EARS models, the ROXA-T1000 does not offer selectable backplate (rear housing) materials such as wood.
As a result, there are no subtle variations in sound caused by backplate material choices, allowing the ROXA-T1000 to deliver a consistently stable tonal character.
Comparison with ROXA-S100:
Compared to the ROXA-S100, the ROXA-T1000 shows a significant improvement in sound clarity and definition.
Transient attack and decay are faster, allowing mid and high frequencies to exhibit richer resonance and more expressive decay.
There is also a clear difference in treble extension, sense of openness, and overall listening comfort.
The ROXA-S100 delivers a character typical of a closed-back design, with slightly emphasized bass and a relatively compact soundstage.
In contrast, the ROXA-T1000 offers a more open and comfortably wide soundstage, while keeping the sound image close and immersive.
While the quantity of bass is slightly reduced compared to the ROXA-S100, the quality of the low frequencies is greatly improved.
Bass outlines are more defined, with better elasticity and faster attack, resulting in a more controlled and refined low-end presentation.
In terms of tonal character, the ROXA-S100 leans toward a warmer sound influenced by its wooden elements,
whereas the ROXA-T1000 is tuned closer to a neutral and slightly cooler balance.
Even so, the edges remain smooth and well controlled, producing a sound that is clear yet gentle, and easy to listen to for extended periods.
Comparison with LOAK2-TX03 / TX00:
Since the ROXA-T1000 is based on the tuning of the LOAK2-TX03 and the TX00 (an unreleased model), its overall sound direction is very similar to these models.
However, the housing design has been revised, and the improved fit during wear enhances clarity and stability, resulting in playback with less image fluctuation.
In addition, although the difference is subtle, the ROXA-T1000 offers slightly greater openness in the soundstage and a richer sense of decay.
That said, because the sound signatures of the TX03, TX00, and the ROXA-T1000 are extremely close, customers upgrading from these models are eligible for a significant discount through our trade-in program.

About the Batch-Based Production:
Like the ROXA-S100, the ROXA-T1000 is produced using a batch-based made-to-order system.
The first batch will be manufactured in a limited quantity and produced only after orders are received.
Decisions regarding whether to proceed with a 2nd or 3rd batch will be made on a case-by-case basis, taking into account customer demand, parts availability, and overall production conditions.
This production approach is necessary due to ongoing fluctuations in exchange rates, global conditions, and the availability and pricing of components, making long-term planning difficult.
Depending on circumstances, the ROXA-T1000 may be discontinued.
As a result, the ROXA-T1000 may be available only as a first batch, and even if subsequent batches are produced, prices may increase due to changes in component costs and manufacturing expenses.
At 634EARS, quality is always our highest priority.
We move forward with the next batch only when the conditions at that time allow us to maintain our standards.
By producing in small, controlled quantities, we aim to deliver products that strike a careful balance between quality and price.
If you are considering the ROXA-T1000, we hope you will understand this background and choose to purchase it at a timing that feels right for you.
