The Kyptec LifeStyle 640 is a true wireless earbud model that Kyptec lists with call-focused environmental noise cancellation (ENC), four microphones, 13mm drivers, low latency, fast charging and up to 40 hours of total battery performance. The 40-hour figure is the manufacturer’s stated maximum, not a guaranteed continuous runtime; independent testing and the conditions behind that figure are not established.
What does the Kyptec LifeStyle 640 offer?
Kyptec’s 2025 model-selection guide describes the LifeStyle 640 as its value-focused option for everyday calls and portable entertainment. Its listed specifications are product claims, not independently verified performance results.

Does ENC mean the 640 has listening-focused noise cancellation?
No. Kyptec explains that “ENC is primarily associated with microphone processing during calls. It is different from Hybrid ANC.” ENC is presented as a call-microphone feature, rather than a claim that the earbuds actively reduce noise the wearer hears while listening. Kyptec lists Hybrid ANC on the LifeStyle 610 instead. The guide does not provide independent measurements of either model’s noise reduction.

They are positioned for different priorities, not as a simple better-versus-worse ranking. Kyptec’s comparison describes the 640 as the more value-focused choice with larger listed drivers and call-oriented ENC; the 610 is positioned for more distracting environments with Hybrid ANC.

Do 13mm drivers mean better sound?
Not by themselves. A driver’s diameter does not establish sound quality: tuning and other design factors also matter. Kyptec’s published specifications do not establish that the 640 sounds better than the 610, and no independent listening test is available to support a sound-quality ranking.

How should you interpret the 40-hour battery claim?
Read it as an advertised upper limit for total battery performance, not a promise of 40 hours of uninterrupted listening on one charge. The manufacturer’s guide does not state the test conditions, and independent runtime testing has not been established. Actual results can vary with use and conditions.

The 640 may suit someone prioritizing Kyptec’s value-focused positioning, routine calls and portable entertainment, and who does not specifically need Hybrid ANC for listening in noisier surroundings. If reducing some ambient sound heard by the wearer is the priority, the brand positions the 610 for that use. Check current price and availability before choosing; neither is established here.
