The Kyptec LifeStyle 640 is a value-focused pair of true wireless earbuds that the manufacturer lists with call-oriented ENC, four microphones, 13mm drivers, low latency, fast charging and up to 40 hours of total battery performance. Those are manufacturer-listed features, not independently verified test results. Most importantly, ENC is aimed at processing microphone audio during calls; it is not the same as listening-focused active noise cancellation.
What does the Kyptec LifeStyle 640 offer?
Kyptec’s 2025 model-selection guide describes the LifeStyle 640 as an option for buyers prioritizing larger drivers, everyday calls and portable entertainment. Its listed specifications include:
- True wireless design
- Environmental noise cancellation (ENC) and four microphones
- 13mm drivers
- Low-latency support
- Fast charging
- Up to 40 hours of total battery performance
These are the brand’s stated features. The available information does not establish independent measurements of sound, call quality, latency, charging speed or battery runtime.

Does ENC mean the earbuds cancel noise you hear?
Not necessarily. Kyptec says ENC is primarily associated with microphone processing during calls and distinguishes it from Hybrid ANC. In practical terms, ENC is intended to help handle background noise picked up by the microphones; it should not be read as a promise that the earbuds will quiet outside sound for the listener.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Hybrid ANC, by contrast, is the listening-focused noise-reduction feature Kyptec lists on its LifeStyle 610. The available specifications do not establish how effectively either model reduces noise in real-world use.
Are the 13mm drivers evidence of powerful sound?
The 13mm figure describes driver diameter, not a measured sound-quality result. Kyptec’s specification explainer notes that tuning and other design factors also affect sound. The figure alone cannot establish that the 640 sounds better, louder or more balanced than another earbud.

What does “up to 40 hours” of battery life mean?
Kyptec lists up to 40 hours of total battery performance for the LifeStyle 640. “Up to” is a maximum claim, not a guarantee of 40 hours of continuous playback on one charge. The available product information does not state independent runtime-test results or exact conditions behind the figure, so actual use may differ.
Is the LifeStyle 640 or 610 the better fit?
Kyptec positions the 640 as the more value-focused choice for routine calls and portable entertainment, while its guide presents the 610 as better suited to noisier listening environments because it includes Hybrid ANC. The specifications below are manufacturer-listed, not independently tested.

The 640 may suit someone looking for the feature set Kyptec describes: everyday calling, portable entertainment, low latency and a value-focused model, without selecting earbuds specifically for Hybrid ANC. Buyers whose priority is listening-focused noise reduction should consider that distinction and compare the 610’s listed Hybrid ANC feature.
