By keeping ergonomics in mind, it is designed to fit perfectly and naturally in your ear curves, providing a snug fit. However, you can choose from three different sizes of ear tips, ensuring you get the right one for your ears. Even with the extended use of 2 to 3 hours, you will not have any ear fatigue. For budget-conscious individuals, these earbuds are the best fuss-free choice.
Sound Quality
The Renimer ST01A boasts a fantastic sound profile that is both vibrant and approachable in a budget-friendly set of earbuds. The ST01A utilizes 10mm dynamic drivers as of TOZO T12 and appears to be geared toward a V-shaped audio spectrum, characterized by a bassy and treble-rich sound with a slight midrange emphasis. The tuning is good, especially with casual listeners who prefer the modern music genres such as EDM, hip-hop, and pop music. Bass is deep, punchy, non-overwhelming, and adds fun to each song. Nonetheless, when turned up too loud, the bass tends to interfere with the quality of the vocals. Trebles are sufficiently crisp to pick up fine details, such as hi-hats or synth spritzes, although they may seem piercing on lines with poor mixes or singers with high voices.
| Attribute | Performance Summary |
| Driver Size | 10mm Dynamic Drivers – Solid low-end performance |
| Bass | Deep and punchy, slightly loose at higher volumes |
| Mids | Clean but somewhat recessed; vocals sometimes pushed back |
| Treble | Bright with detail, borderline sharp at high volume |
| Max Volume | Loud enough for noisy environments |
| Distortion | Minor, mostly above 90% volume |
| EQ Options | No native app, customizable via phone EQ |
Although the customization of EQ is not improved by the absence of a specific companion app, the sound quality is generally balanced, considering the price. Midrange vocals and instruments are clear, and at times slightly recessed, particularly in acoustic-centered songs or orchestral works. The performance is overall fatigue-free and enjoyable, particularly when played at moderate listening volumes. Calls, podcasts, and general video streaming are clear and intelligible. Distortion is also low unless you push it to full volume, where it becomes a little boomish and lacks definition in the bass. The ST01A is a straightforward amp, and surprisingly, it performs well in most real-life listening situations.
Best Genres for ST01A
The audiophile may not be choosing the Renimer ST01A, but for casual listeners, these earbuds offer an awe-inspiring and bold sound quality. These earbuds are impressive for bass-heavy genres, so if you’re the type who appreciates them, get these.
Active Noise Cancellation (ANC)
In such low-budget and affordable earbuds, you won’t find the Active Noise Cancellation (ANC) feature, which is perfectly fine. However, it performs impressively in terms of passive noise isolation, and the snug fit with eartips further enhances its performance.
So the ambient and background noises in a moderate environment are controlled to some extent. However, when working in an indoor environment, such as a coffee shop, earbuds do a great job of blocking background noises. However, high-pitched sounds are still audible.
Selecting the appropriate ear tip size has a notable impact, as a tighter seal significantly enhances isolation. But it is perfect for casual listeners.
Call Quality & Microphone Performance
The call quality of the Reminer ST01A is good in an indoor and quiet setup. They pick up voices and sounds naturally and clearly, and users do not face any distortion. The earphones are ideal for meetings, video calls, and casual discussions since they efficiently capture voice without causing undue muffling. When tested in outdoor setup with background noise and rushy, the earbuds’ performance may become limited.
Due to background noise, you may hear a muffled voice and experience a drop in sound quality even with ENC. Basic noise reduction algorithms are included in the earphones; however, they are insufficient to completely block out your speech in noisy environments. In summary, the Renimer ST01A is a competent option for daily calls in calm environments but may struggle in louder outdoor scenarios.
Controls & App Features
These earbuds are designed with simplicity as the priority. It offers touch controls and is very responsive to them. The only drawback is that it lacks a comprehensive app to control the features. However, if it’s about usability, then these earbuds are truly impressive.
Touch Controls
To perform various actions and control your earbuds, simply tap; no buttons are required. For better control over your earbuds, here are some light taps instructions that you can follow:
Gesture Accuracy
For such budget-friendly earbuds, the gesture control sets the standards high. The earbuds will automatically respond very promptly with no dropouts when you are jogging, walking, or on a call with someone. The response time is also very smooth, and it will easily recognize the gesture, responding promptly and precisely. It makes them dependable and practical for control while driving.
App Features
| Feature | Available? |
| EQ Adjustment | ❌ |
| Custom Touch Setup | ❌ |
| Firmware Updates | ❌ |
| Voice Assistant | ✅ (via long press) |
Unfortunately, there is no companion app for the ST01A earbuds. If you’re someone who wants high customization via an app, then you should choose a different pair of earbuds. Otherwise, these earbuds are perfect for daily listeners and active users.
Connectivity & Latency
The renewed Renimer ST01A earbuds are ready to enjoy a stable and energy-efficient wireless connection with Bluetooth 5.3. Connection is fast and straightforward, and the earbuds instantly connect with any paired device, only a few seconds after being removed from the case.
The strength of connection is good up to a distance of 30-33 feet (10 meters) inside, and there are very few dropouts even behind two walls. Nonetheless, the ST01A lacks the multi-point connectivity feature, which means you must manually disconnect one device before connecting to another. This can be disadvantageous to customers who often use a phone, laptop, or tablet.
When it comes to latency, earbuds are suitable for casual media consumption. Videos played on websites such as YouTube or Netflix have very little audio lag, and the videos are played synchronously. In the case of mobile gaming, latency is not critically bad but noticeable, which is acceptable when playing a casual game. However, in a competitive match, it is not ideal.
Connectivity Highlights
In general, the ST01A offers decent wireless performance that is sufficient for daily use, but users who require low latency may need to look elsewhere.
Battery Life & Charging
The Renimer ST01A claims a very high battery rating in this price range, offering a continuous playback time of 6 hours on a single charge. However, with the charging case, the battery life can be extended up to 24 hours, which is impressive. When the SRT01A is tested in real-life conditions, the battery timing fluctuates to 5.5 hours, which is not far from the claimed value. The charging case is also sturdy enough to charge the earbuds 4 to 5 times. The earbuds utilize a USB-C Port charging cable, making them convenient for all types of users.
Some key points about the charging of ST01A are mentioned below:
Water Resistance & Durability
The Renimer ST01A earbuds feature IPX7 Water Resistance Rating, indicating that the device can be submerged in water up to 1 meter in depth for 30 minutes. This does not mean they will be swim-resistant but they are well-protected against sweat, rain, and splashes, so they may be used during exercises, outdoor running, or daily commutes when the weather can change at any moment.
Through the testing, the ST01A was quite resistant to heavy exercise, such as sweaty gym time, and even light rain. The firmness also prevents moisture from easily leaking into the sound drivers or mic holes. The charging case, however, is not water-resistant and should therefore not be exposed to moisture. The ST01A is waterproof, so whether you’re working out in the gym, running at the park, or cleaning up after a rainstorm in the streets, it’s unlikely to skip a beat.
Customization
The customization features in the STO1A are limited due to the absence of a companion feature. This means users cannot perform EQ customization, remap touch controls, or create customized sound profiles.
The good news is that the earbuds feature a built-in balanced sound profile. The built-in sound profile is ideal for a wide range of music genres, ensuring that both audiophiles and casual listeners will enjoy the earbuds.
Price & Value for Money
The price range of Renimer ST01A is affordable for all people. These mid-range earbuds are priced between 25-35$. In comparison to other earbuds in this price range, the Renimer performs significantly better. The main competitors of these earbuds are JLab Go, SoundPEATS TrueFree 2, and TOZO T6. Unlike other competing earbuds, the ST01A features Bluetooth 5.3, fast charging, an IPX7 Water Resistance Rating, and an impressive 30-hour battery life. However, lacking ANC, App support, and wireless charging are still some of the drawbacks. Both in its build quality and usage, the ST01A punches above its weight. The controls are responsive around the touch buttons, it fits snugly during exercises, and the sound output is balanced for use with music, podcasts, and calls.
Even the most audiophile or demanding power user may wish to have more customization options or higher audio resolution. Still, the average one will be more than satisfied with this pair of earbuds.
