Summary

The Samsung Galaxy Buds4 Pro are 2026 premium ANC earbuds, model SM-R640, with IP57-rated buds and sealed ear tips. Their best features are Galaxy-exclusive, so check your phone and your fit: several advanced functions need a compatible Galaxy device, and owners report both excellent and painful fits with the same tips.

Strengths

  • SoundGuys rated them 8/10 for sound and premium use and called them a strong high-end choice for Samsung phone owners.
  • A six-month follow-up found the reviewer still using them as a daily driver, valuing sound and device switching.
  • TechRadar’s hands-on preferred the Pro to the standard Buds4 for fit, isolation and sound.
  • Around six hours with ANC on plus 24 hours from the case.
  • IP57 water resistance on the earbuds, with sealed ear tips supplied in three sizes.
  • An owner coming from Sony over-ear headphones found the ANC subjectively stronger and the buds good for running.

Weaknesses

  • Many headline features, including 24-bit/96 kHz audio, 360 Audio, Live Translate, head gestures and Gaming Mode, need compatible Galaxy hardware.
  • iOS and generic Bluetooth devices do not receive the full feature set.
  • Owner fit reports are polarised, from excellent to painful or gradually loosening even after changing tips.
  • One owner reports touch controls stopping and mismatched ANC and Ambient behaviour between ears after calls.
  • One owner reports the buds connecting for audio but not appearing correctly in settings or Wearable controls.
  • The case is excluded from IP57, and the sealed batteries are not documented as user-replaceable.

Ecosystem features

Galaxy Buds4 Pro make their strongest case inside Samsung’s ecosystem. Samsung identifies the 2026 model as SM-R640 and reserves several premium features, including 24-bit/96 kHz audio, 360 Audio, Live Translate, head gestures and Gaming Mode, for compatible Galaxy hardware and software. The Galaxy Wearable app is available on compatible Android devices, but iOS and generic Bluetooth devices do not receive the full feature set, so a shopper comparing feature lists may overestimate what works outside a Galaxy phone. That dependence is the main reason SoundGuys frames the product as a strong high-end choice for Samsung phone owners and notes that value is weaker outside Samsung devices.

Fit and comfort

The main purchase uncertainty is physical fit. Current owners report both excellent fit and painful or unstable fit with the same supplied tip set, with several describing a bud gradually loosening or causing ear pain despite trying different included tips. TechRadar’s hands-on preferred the Pro’s sealed fit and isolation to the open standard Buds4, so the design can work well, but fit is highly individual and should be tested early inside the return window.

Battery and reliability

Battery is competitive on paper and variable in owner use. TechRadar’s launch coverage reports about six hours with ANC on plus 24 hours from the case, and a one-month owner reports about six hours with ANC on but noticeable overnight case drain, which highlights standby-loss variability rather than contradicting the controlled figure. SoundGuys rated the earbuds 8/10 and its six-month follow-up found the reviewer still using them daily, particularly valuing Samsung ecosystem features, sound and device switching. Software cautions exist but are too sparse to establish prevalence: one launch-period owner reports touch controls stopping and mismatched ANC and Ambient behaviour after calls, and a separate owner reports the buds working for audio while failing to appear correctly in settings or Wearable controls. The earbuds are sealed, with no documented user-replaceable battery.

Which model this is

This page covers the Samsung Galaxy Buds4 Pro, model SM-R640, released in 2026. US colour SKUs include SM-R640NZWAXAR for White, with Black and Pink Gold under the same SM-R640 family. Do not merge it with the standard Galaxy Buds4 or the earlier Buds3 Pro, which are different models with different feature sets. Treat the advanced audio, translation and gesture features as Galaxy-phone features until confirmed against your specific paired device.
