X1 Meeting Interpreter Hub

Bone voiceprint pickup technology refers to the built‑in bone voiceprint sensor inside the earbuds. When the user speaks, the sensor captures vibration signals within the ear canal to accurately determine whether the user is currently speaking. Through Timekettle’s proprietary hybrid algorithm that combines bone voiceprint signals with microphone signals, the earbuds can clearly extract the user’s voice even in extremely noisy environments, separating it from background noise.

(In simple terms, the earphone’s recording channel is activated only while the user is speaking, significantly enhancing noise reduction performance.)

The main differences are:

1. No extra devices or complicated setup
   The X1 Meeting is a standalone terminal device – it can be used without downloading an app, registering an account, or connecting to a mobile phone. Ordinary translation earphones and mobile apps typically require a smartphone, software installation, and login.
2. Designed for multi‑person real‑time simultaneous interpretation
   The X1 Meeting supports simultaneous interpretation of up to 5 languages and can serve up to 50 listeners, making it ideal for classrooms, meetings, and other group scenarios. Ordinary translation earphones or apps are mostly designed for one‑to‑one translation and cannot handle multi‑language, multi‑person simultaneous interpretation.
3. Superior voice pickup and noise reduction
   The X1 Meeting uses bone conduction technology to accurately capture the speaker’s voice even in noisy environments, greatly improving recognition accuracy. Ordinary devices often suffer from poor pickup in loud settings.
4. Fully independent operation – no phone required
   Ordinary translation earphones usually need to connect to a phone via Bluetooth and rely on an app. The X1 Meeting is a complete device on its own – no need to distribute phones or rely on a network (core functions can be used offline).

In short, the X1 Meeting is an all‑in‑one device built for multi‑person, multi‑language, real‑time simultaneous interpretation scenarios. Ordinary translation earphones and mobile apps are better suited for personal, one‑on‑one, basic translation needs.

They are designed for different use cases and complement each other:

• Positioning

X1 Meeting focuses on multi‑person cross‑language collaboration (e.g., group meetings, classrooms, training sessions).

W4/W4 Pro focuses on one‑on‑one, in‑depth conversations (e.g., coffee shop chats, business negotiations).

• Scenarios

X1 Meeting – Ideal for scenarios where multiple people need real‑time interpretation simultaneously, such as team meetings, lectures, or workshops.

W4/W4 Pro – Better suited for private, two‑person interactions that require natural, continuous dialogue.

In short, the X1 Meeting is built for group communication, while the W4/W4 Pro excels at personal, face‑to‑face conversations. They work together to cover different cross‑language needs.

The X1 Meeting brings several hardware and software upgrades:

Hardware

• Host performance – Unchanged from the old X1 (consistent core performance).
• Headset pickup – Added a bone conduction microphone, which improves voice recognition accuracy in moderate‑to‑high noise environments and reduces crosstalk between speakers.
• Battery life – earbuds' battery increased from 45mAh to 50mAh, extending battery life from 2.5 hours to 3 hours.

Software

• Multi‑person translation mode – Stability and usability have been significantly optimized.
• Meeting capacity – Supports up to 10 X1 Meeting hosts and 50 peripheral devices joining the same meeting simultaneously.

No, it's not mandatory. You may wear only one earbud, but you must ensure that this earbud is the device currently selected by the host as the sound source. The host can switch the active recording earphone and check its status on the host screen.

External earbuds are not supported. However, the device does support connecting a wireless lavalier microphone via the Type‑C interface.

Please note: When using the wireless lavalier microphone, the device can only output the user's speech for translation – it cannot play back the translated audio to the user.

No, it does not. Noise reduction relies on the bone conduction chip and algorithm built into the X1 Meeting earbuds. Peripheral devices like mobile phones use omnidirectional microphones, which cannot achieve directional voice pickup. It is recommended to keep the environment quiet while speaking via such devices to avoid interference from others; otherwise, recognition accuracy will decline.

The system supports up to 10 X1 Meeting hosts (serving as speaking endpoints) and 50 peripheral devices (such as mobile phones, tablets, and computers) as receiving endpoints, all online simultaneously.

It supports up to 5 languages for real‑time mutual translation.

Yes, currently, all modes remain consistent in supported languages, core functions, and setting logic. In the future, the number of supported languages will continue to increase and be updated.

Offline translation accuracy is lower than that of the New T1 model. Since the X1 Meeting is primarily designed for Wi‑Fi‑enabled scenarios such as meeting rooms, online translation is strongly recommended. Additionally, creating a meeting room itself requires an internet connection.

• Earphone battery life: Approximately 3 hours (upgraded from the older model).
• Main unit battery life: Up to 8 hours, with actual usage depending on the mode – average battery life ranges from 7 to 8 hours.

Charging method: Both the main unit and the earphone charging case are charged via the included USB‑C cable (standard USB‑C port).

Please try the following steps:

1. Take the earphones out of the charging case, then put them back in, making sure they are firmly seated. Wait 2 seconds, then take them out again.
2. If the issue persists, wipe the charging pins on the earphones with a clean cloth or an alcohol wipe, then repeat step 1.
3. Try inserting and removing the earphones from the case several times to see if that resolves the problem.
4. If none of the above works, please contact customer service for a return or replacement.

No, the X1 Meeting can be used under normal mobile networks or public Wi‑Fi without geographic restrictions. However, some enterprise or school intranets have firewalls installed. In such cases, you may need to add the X1 Meeting server domain name or IP address to the allowlist to use it normally.

The X1 Meeting has an operating temperature range of 0°C to 40°C (32°F to 104°F). Within this range, the device operates stably. Using it in temperatures below 0°C is not recommended and may affect performance or battery life.

Yes, data security is a top priority for the X1 Meeting. The device employs multiple layers of protection:

• Bank‑grade encryption: The server uses bank‑level data encryption to ensure communication privacy and security.
• End‑to‑end encryption: The BabelOS security system follows Responsible AI standards and encrypts data throughout the entire transmission process.
• Three‑layer privacy protection: The system is built on bank‑grade encryption and data transmission, effectively securing conversations from interception.

Regarding cloud uploads: While translation requires an internet connection and the system utilizes the UniSmart translation cloud for processing and regular vocabulary updates, translation data is stored locally only, without backing up to servers. This ensures full control over your information and protects business confidentiality.

For the complete privacy policy, please refer to the official Timekettle documentation.

Here’s how to handle exporting history and related issues:

1. The exported file appears garbled
   To ensure compatibility across all languages, the X1 Meeting uses UTF‑8 encoding only. If you open the exported file with software like Microsoft Word, you must manually select UTF‑8 encoding when opening the file. Alternatively, you can open the file directly with a plain text editor such as Notepad (Windows) or TextEdit (Mac) – they typically handle UTF‑8 automatically.
2. Cannot see folders when connecting X1 Meeting to a Mac computer
   The X1 Meeting runs on an Android‑based system. Connecting it to a Mac requires cross‑platform file transfer. You will need to install a third‑party MTP (Media Transfer Protocol) client on your Mac. For users outside mainland China: Search for and download MacDroid – Android File Transfer from the Mac App Store. For users in mainland China: Search for MacDroid – Android Manager (or similar local versions). Alternatively, you can download Google’s official Android File Transfer tool from https://www.android.com/filetransfer/ (note: a VPN may be required to access this link in some regions).

Once the proper MTP client is installed, you can browse the X1 Meeting’s internal storage and locate the exported history files normally.
