Noise 4

Manufacturer: Noise

The Noise 4 is an over-ear headphone designed for extended wireless use, offering both Bluetooth and wired connectivity to suit different listening setups. Weighing 288 g and built with a foldable form factor, it strikes a practical balance between portability and comfort. One of its standout characteristics is its 70-hour battery life, supported by a two-hour charge time via USB Type-C, making it well-suited for long listening sessions without frequent recharging.

On the technical side, the Noise 4 uses a 40 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, with passive noise reduction to help limit ambient sound. Bluetooth 5.4 handles wireless connectivity with an audio latency of 40 ms and a maximum range of 10 m, while multipoint pairing allows simultaneous connection to two devices. The headphone also includes a noise-canceling microphone and on-device controls, and its IPX5-rated sweat resistance adds a degree of durability for active use.

Pros
  • A 70-hour battery life means the headphones can go extended periods between charges, reducing how often you need to reach for a cable
  • Full charge is achieved in just 2 hours via USB Type-C, which is a widely available and convenient charging standard
  • Multipoint connectivity allows simultaneous pairing with two devices, making it easy to switch between a phone and laptop without re-pairing
  • The foldable build and detachable, tangle-free cable make the headphones practical to transport and store
  • An IPX5 rating provides sweat resistance, adding durability for use during physical activity
  • The on-device noise-canceling microphone enables hands-free calls without requiring a separate headset
Cons
  • No active noise cancellation means unwanted background sound is only partially filtered through passive isolation
  • The Bluetooth range is limited to 10 m, which restricts movement when using the headphones wirelessly
  • No advanced audio codecs such as aptX, LDAC, or AAC are supported, limiting wireless audio quality options
  • Fast pair and NFC pairing are not available, making the initial Bluetooth setup less convenient
  • A travel bag is not included, so protecting the headphones during transport requires a separately sourced case
  • There is no ambient sound mode, so hearing surrounding environment requires removing the headphones entirely
Who is this for?

These headphones suit users who prioritize extended listening sessions without frequent recharging, given the 70-hour battery life. The IPX5 sweat resistance and foldable build make them a practical choice for active, on-the-go use such as commuting or gym sessions where durability and portability matter. The ability to connect to two devices simultaneously via multipoint pairing also makes them well-matched for people who regularly switch between a work laptop and a personal phone throughout the day.

Who is this NOT for?

Users who need active noise cancellation for focused work in loud environments will find this model lacking, as it relies solely on passive isolation. Those who demand high-fidelity wireless audio through codecs like LDAC, aptX, or AAC will also be underserved, since none of these are supported. Additionally, listeners who value spatial audio or ambient sound awareness without removing their headphones will need to look elsewhere, as neither feature is available on this model.

Final Verdict

The Noise 4 is a straightforward over-ear headphone that makes a clear case for itself through its 70-hour battery life and practical design features like foldability, sweat resistance, and dual-device multipoint pairing. It is well-suited to everyday wireless listening and active use, where endurance and convenience carry more weight than audio codec support or advanced noise management. Those with more demanding requirements — particularly around sound transparency, ANC, or high-resolution wireless audio — will find its feature set limited. For users whose priorities align with what it genuinely offers, the Noise 4 delivers a dependable, no-frills experience that holds up well in day-to-day scenarios.
