Samsung Galaxy Buds 4

Manufacturer: Samsung

The Samsung Galaxy Buds 4 are a true wireless earbud option sitting in the crowded wireless earbuds category, offering a compact open-ear fit and weighing just 9.2 grams per bud. They include active noise cancellation, an ambient sound mode for situational awareness, and in-ear detection that pauses playback automatically when removed. A built-in translator, notification readout, and six-microphone setup with noise-canceling capability round out the feature set for everyday use.

On the connectivity side, the Buds 4 run on Bluetooth 6.1 with LE Audio and Auracast support, along with AAC codec compatibility and multipoint pairing for up to two devices simultaneously. The earbuds carry a 45 mAh battery rated for 6 hours of playback, or 5 hours with ANC active, while the 515 mAh charging case extends total usage to 24 hours. Charging is handled via USB-C with fast charging support, and the case reaches a full charge in roughly 1 hour and 8 minutes. An 11 mm driver covers the standard 20 Hz to 20,000 Hz frequency range, and spatial audio is supported for compatible content.

Pros
  • Active noise cancellation helps block ambient sound during listening or calls
  • Six-microphone array with noise-canceling capability supports cleaner voice pickup
  • Bluetooth 6.1 with LE Audio and Auracast support reflects a modern wireless standard
  • Multipoint connection allows simultaneous pairing with two devices
  • Built-in translator adds a practical utility beyond standard audio playback
  • A travel bag is included in the box, offering basic protection when not in use
Cons
  • No wireless charging support, requiring a physical USB-C connection each time
  • Battery life drops from 6 hours to 5 hours when ANC is active
  • No aptX codec variants or LDAC are supported, limiting high-quality audio codec options
  • Bluetooth range is capped at 10 meters, which may be restrictive in some scenarios
  • Wingtips are not included, which may affect earbud stability during physical activity
Who is this for?

These earbuds suit everyday users who want a versatile wireless listening experience with practical smart features built in. The combination of active noise cancellation and ambient sound mode makes them well-suited to commuters and office workers who need to switch between focused listening and situational awareness. The built-in translator and notification readout add hands-free utility that appeals to users who rely on their earbuds throughout a busy day, while the IP54 sweat resistance and true wireless design make them a reasonable fit for light workouts and on-the-go use. Multipoint pairing with two devices also makes them practical for people who regularly switch between a phone and a laptop.

Who is this NOT for?

Users who prioritize high-resolution audio codec support will find these earbuds limiting, as there is no LDAC, aptX, or any aptX variant available — only AAC is supported alongside LE Audio. Audiophiles or those seeking the most detailed wireless audio transmission would likely find the codec options insufficient for their needs. Additionally, the 5-hour ANC battery life may fall short for long-haul travelers or users who spend extended periods away from a charging source, especially since wireless charging is not supported and the case must be plugged in each time. Users who need a secure, lock-in fit for intense physical activity may also find the lack of wingtips a drawback.

Final Verdict

The Samsung Galaxy Buds 4 present a well-rounded package for everyday wireless earbud users, combining active noise cancellation, a six-microphone noise-canceling array, and modern Bluetooth 6.1 with LE Audio and Auracast into a compact, sweat-resistant form. Practical additions like the built-in translator, multipoint pairing, and ambient sound mode give them genuine day-to-day versatility that goes beyond basic audio playback. Where they show their limits is in audio codec depth and charging flexibility — the absence of LDAC or aptX support and the lack of wireless charging may give pause to more demanding users. Still, for commuters, office users, and light fitness enthusiasts who value smart feature integration alongside reliable ANC, the Galaxy Buds 4 represent a capable and thoughtfully equipped option within the wireless earbuds category.
