Energy Sistem Silent ANC specifications and in-depth review

Energy Sistem Silent ANC

Manufacturer: Energy Sistem

The Energy Sistem Silent ANC is an over-ear headphone designed for both wired and wireless use, offering a foldable build that weighs 267 g and includes a detachable 1.2 m tangle-free cable. One of its defining characteristics is its 100-hour battery life, which drops to 60 hours when active noise cancellation is engaged, charged fully in just 2 hours via USB Type-C.

On the technical side, the headphone uses a 40 mm driver covering a frequency range of 20 Hz to 20,000 Hz at 16 Ohms impedance, paired with Bluetooth 5.4 and AAC codec support across a maximum wireless range of 20 m. It features four microphones with noise-canceling capability, an ambient sound mode, and multipoint connectivity for up to two devices simultaneously, with an audio latency of 175 ms.

Pros
  • Battery life reaches 100 hours in standard use, and still holds 60 hours with ANC active, reducing how often it needs charging
  • Charges fully in just 2 hours via USB Type-C, and a battery level indicator makes it easy to track remaining power
  • Supports simultaneous connection to two devices via multipoint, which is practical for switching between a phone and a laptop
  • Foldable build with a detachable, tangle-free cable makes it easier to pack and carry
  • Four noise-canceling microphones and an ambient sound mode add meaningful versatility for calls and situational awareness
  • Both active noise cancellation and passive noise reduction are present, offering two layers of sound isolation
Cons
  • Audio latency is rated at 175 ms, which may be noticeable when watching video or playing games
  • No high-resolution codec support — aptX, LDAC, LDHC, and similar options are all absent, limiting wireless audio quality
  • No fast pairing or NFC pairing, so connecting to a new device requires going through the standard Bluetooth process
  • No in/on-ear detection, meaning music does not pause automatically when the headphones are removed
  • No travel bag is included despite the foldable design, offering no built-in storage protection
  • No water resistance of any kind, leaving the headphone vulnerable to rain or sweat
Who is this for?

This headphone suits users who need long listening sessions without frequent recharging, given its 100-hour battery life and quick 2-hour charge time via USB Type-C. The combination of active and passive noise cancellation makes it a practical fit for office environments or commuting, where blocking out ambient noise matters. Its foldable design, detachable cable, and multipoint support for two devices also make it a reasonable choice for those who regularly switch between a phone and a computer throughout the day.

Who is this NOT for?

Users who prioritize high-fidelity wireless audio will find the lack of advanced codec support — with no aptX, LDAC, or similar options available — a notable limitation. The 175 ms audio latency makes it poorly suited for gaming or video editing, where synchronization between audio and visuals is important. Additionally, the absence of any water resistance means it is not a reliable choice for outdoor workouts or use in wet conditions.

Final Verdict

The Energy Sistem Silent ANC is a well-rounded over-ear headphone that makes a strong case for users who value endurance and versatility in everyday listening. Its 100-hour battery life combined with active noise cancellation and passive noise reduction addresses both practical and comfort-oriented needs, while the foldable build, detachable cable, and dual-device multipoint support add genuine day-to-day convenience. That said, the absence of advanced wireless codecs and the 175 ms latency signal that this is not a headphone aimed at audiophiles or media-production use. For commuters, remote workers, or anyone seeking a dependable all-day wireless headphone with solid noise isolation and long-lasting power, the Silent ANC delivers a focused and functional package.
