Lenovo TC3401

Manufacturer: Lenovo

The Lenovo TC3401 are true wireless earbuds designed with an open-ear fit, making them a practical option for users who prefer to stay aware of their surroundings during everyday use. They carry an IPX5 rating for sweat resistance, which adds a degree of durability for active use, and come with a travel bag included for portability. With four built-in microphones and a noise-canceling mic system, the TC3401 is also set up for hands-free calls and can function as a full headset with mute functionality and voice prompts.

The TC3401 connects via Bluetooth 5.3 with a maximum wireless range of 10 metres and uses USB Type-C for charging, though wireless charging is not supported. The earbuds deliver up to 10 hours of playback on a single charge, with the charging case extending total battery life to 30 hours combined, and fast charging is available to help minimize downtime. The frequency response spans 20 Hz to 20,000 Hz across stereo speakers, and a battery level indicator keeps users informed of remaining charge. Advanced audio codecs such as aptX, LDAC, and AAC are not supported.

Pros
  • Four microphones combined with a noise-canceling mic make it a capable option for calls and voice communication
  • Fast charging support helps reduce downtime when the battery runs low
  • The charging case adds 20 hours of additional battery life, bringing the combined total to 30 hours
  • A travel bag is included in the box, adding practical portability out of the box
  • IPX5 sweat resistance makes it suitable for use during physical activity
  • Bluetooth 5.3 and USB Type-C connectivity reflect a reasonably current hardware specification
Cons
  • No active noise cancellation or passive noise isolation, so the open-ear design offers no protection from ambient noise
  • Advanced audio codecs such as LDAC, AAC, and all aptX variants are absent, limiting wireless audio quality options
  • Wireless charging is not supported, requiring a wired connection every time
  • No fast pairing or NFC pairing, meaning the initial setup process is more manual
  • No in/on-ear detection, so music does not pause automatically when the earbuds are removed
  • There is no find device feature, making it harder to locate a misplaced earbud
Who is this for?

The Lenovo TC3401 is well suited to users who spend a significant portion of their day on calls and virtual meetings, thanks to its four-microphone setup with noise-canceling capability and full headset functionality with a mute function. The open-ear design and absence of any noise isolation make it a natural fit for people who need to remain aware of their environment while listening — such as those working in shared offices or moving around public spaces. With 30 hours of combined battery life and fast charging support, it also works well for users who need reliable all-day use without frequent interruptions, and the included travel bag adds convenience for those who carry their earbuds on the go.

Who is this NOT for?

Users who prioritize audio fidelity will find the TC3401 limiting, as it lacks support for advanced audio codecs including LDAC, AAC, and all aptX variants, which restricts the quality ceiling for wireless audio playback. The open-ear fit and complete absence of both active noise cancellation and passive noise isolation make it poorly suited to noisy environments where blocking out external sound is important — such as commuting on public transport or working in loud spaces. Those who rely on convenience features like automatic ear detection for play/pause, NFC or fast pairing, or a find device function will also find those expectations unmet.

The Lenovo TC3401 adopts an open-ear fit and a fully true wireless design with no cables or neckband, and wingtips are not included. The earbuds carry an IPX5 ingress protection rating, making them sweat resistant and suitable for use during physical activity. Audio is delivered through stereo speakers, giving each ear its own dedicated channel for playback.

The Lenovo TC3401 covers a frequency range of 20 Hz to 20,000 Hz, spanning the full standard range of human hearing. The earbuds do not include active noise cancellation or passive noise reduction, meaning ambient sound passes through freely — a characteristic consistent with their open-ear design. A neodymium magnet is not part of the driver configuration.

The Lenovo TC3401 offers 10 hours of battery life per charge, with the charging case contributing an additional 20 hours for a combined total of 30 hours before needing to be plugged in. A full charge takes 2 hours via the wired connection, as wireless charging is not supported. The battery is rechargeable and includes a battery level indicator so users can keep track of remaining charge at a glance.

The Lenovo TC3401 connects wirelessly via Bluetooth 5.3 with a maximum range of 10 metres, and charges through a USB Type-C port. Fast pairing and NFC pairing are not supported, so initial setup follows a standard Bluetooth connection process. On the audio codec side, the earbuds do not support LDAC, LDHC, AAC, or any variant of aptX — including aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — meaning audio transmission relies on the standard Bluetooth codec.

Controls are placed directly on the device, and voice prompts provide audio feedback for various functions. A travel bag is included in the box for added portability. The earbuds do not offer ambient sound mode, in/on-ear detection for auto-pausing playback, a find device feature, or a body temperature sensor.

The Lenovo TC3401 is equipped with four microphones and includes a noise-canceling microphone to help reduce background noise during calls and voice interactions.

Final Verdict

The Lenovo TC3401 is a true wireless earbud designed with communication and situational awareness in mind rather than immersive audio performance. Its four-microphone noise-canceling setup and full headset capability make it a genuinely practical tool for users whose primary use case revolves around calls and voice interaction, while the 30-hour combined battery life and fast charging add meaningful day-to-day convenience. That said, the absence of advanced audio codecs, noise isolation, and several smart features means it is better positioned as a functional communication device than an audio-focused listening experience. For users whose needs align with that profile, the Lenovo TC3401 delivers a focused and coherent set of specifications.
