Third-party reviews

What customers like about Energy Sistem Navy Haru Eco

  • Eco-friendly construction made from 100% GRS-certified recycled plastic
  • Extremely lightweight at only 149g for long-term comfort
  • Solid battery life offering up to 23 hours of playback
  • Fast charging via USB Type-C (full charge in approximately 1.5 hours)
  • Modern connectivity with Bluetooth 5.3
  • Built-in noise-canceling microphone for clearer voice calls
  • Budget-friendly price point with a luxurious feel for the cost

What customers don't like about Energy Sistem Navy Haru Eco

  • Lacks Active Noise Cancellation (ANC) for blocking external environment noise
  • No passive noise reduction or acoustic seal features
  • Non-detachable cable limits replacement options if the wire fails
  • Basic frequency response (20Hz - 20kHz) compared to high-end audiophile models
  • Does not support high-end codecs like aptX or LDAC
  • Design is not foldable, making it less compact for travel
  • No included travel bag or protective case

Verdict

The Energy Sistem Navy Haru Eco is a sustainable over-ear headphone made from 100% GRS-certified recycled plastic, featuring 40mm drivers and Deep Bass technology for punchy audio performance. Key characteristics include Bluetooth 5.3 connectivity with a 20-meter range, an adjustable padded headband for comfort, and a built-in microphone for hands-free calls and voice assistant access. Its main pros are a long 23-hour battery life, a fast 1.5-hour charge time via USB Type-C, and an ultralight 149g design. However, it lacks active noise cancellation (ANC) and a detachable cable for wired use, and it does not support high-end features like spatial audio or foldable hinges for extra portability.
