  • Object classification: Wireless in‑ear audio device / TWS earbuds
  • Brand / Manufacturer: Samsung
  • Model code: SM-R510
  • Available colours: Graphite, Bora Purple, White

Galaxy Buds2 Pro are Samsung's premium stemless in‑ear earbuds designed for high‑fidelity playback, advanced noise control, and close integration with the Galaxy ecosystem.

  • Form factor: In‑ear "snug fit" design
  • Size reduction: Approximately 15% smaller than the original Galaxy Buds Pro
  • Earbud dimensions (H x W x D): 21.6 x 19.9 x 18.7 mm
  • Case dimensions (H x W x D): 50.2 x 50.1 x 27.7 mm
  • Earbud weight: 5.5 g each
  • Case weight: 43.4 g
  • Surface finish: Matte finish on earbuds and case
  • Ear tips in box: Small, Medium, Large

The smaller housing reduces ear‑canal pressure and improves stability for long listening sessions, while the matte texture helps grip and resists visible wear in everyday use.

  • Speaker system: Custom coaxial 2‑way driver
  • Driver details: 10 mm woofer + 5.3 mm tweeter
  • Hi‑Fi mode: 24‑bit audio via Samsung Seamless Codec (SSC HiFi)
  • Audio codecs: SSC HiFi, AAC, SBC
  • Microphone system: 3 High‑SNR microphones per earbud (6 total) plus VPU

Notes on quality mode:

  • 24‑bit Hi‑Fi requirement: Compatible Samsung Galaxy device with One UI 4.0 or later
  • Fit optimization: Galaxy Earbud Fit Test in the Galaxy Wearable app helps maximise bass response and ANC effectiveness

Buds2 Pro combine hardware and codec‑level tuning: the 2‑way acoustic path shapes tonal balance, while SSC HiFi enables higher‑resolution transmission when used with compatible Galaxy devices.

  • ANC: Intelligent Active Noise Cancellation
  • Ambient mode: Ambient Sound (maintains environmental awareness without removing the earbuds)
  • Voice Detect: Automatically lowers media and switches from ANC to Ambient Sound when the user's voice is detected
  • 360 Audio: Direct multi‑channel support (5.1ch / 7.1ch / Dolby Atmos) with enhanced head tracking

Ambient sound tuning:

  • Ambient volume: 5 standard levels, up to 7 with Labs enabled
  • Ambient tone: 5 levels from Soft to Clear
  • Adapt modes: Standard and Adaptive
  • Hearing features: Amplify ambient sound and optional extra‑high ambient volume
  • Independent control: Left/right ambient volume can be adjusted independently

Samsung positions Buds2 Pro as adaptive earbuds: ANC isolates when required, while Ambient and Voice Detect make transitions to conversation and situational listening mostly automatic.

  • Earbud battery: 61 mAh (typical)
  • Case battery: 515 mAh (typical)
  • Playback (ANC on): Up to 5 hours earbuds / up to 18 hours total with case
  • Playback (ANC off): Up to 8 hours earbuds / up to 29 hours total with case
  • Talk time: Up to 3.5 hours earbuds / up to 14 hours total with case
  • Charging: USB‑C wired and Qi wireless charging

Runtime depends on codec, volume, ANC/Ambient usage, and call conditions. The case makes the pair practical for a full day of mixed listening.

  • Bluetooth version: 5.3
  • Bluetooth profiles: A2DP, AVRCP, HFP
  • Pairing and transfer: Easy Pairing, Auto Switch, Auracast support
  • SmartThings Find: Track earbuds with or without the case, including proximity alarm
  • Galaxy AI integration: Interpreter mode and Live Translate when paired with compatible Galaxy phones
  • Voice assistant: Bixby voice wake‑up supported
  • App requirement: Galaxy Wearable app for configuration, updates, and advanced controls
  • Platform requirement: Android 8.0 or later with 1.5 GB RAM or more

Galaxy Buds2 Pro deliver their fullest feature set within Samsung's software stack, where codec switching, device handoff, find‑my tools, and AI translation are tightly integrated.

Built-in sensors:

  • Accelerometer
  • Gyro sensor
  • Hall sensor
  • Proximity sensor
  • Touch sensor
  • VPU (Voice Pickup Unit)

Default touch actions:

Action Default Function
Single tap Play/Pause, stop notification readout
Double tap Next track, answer/end call
Triple tap Previous track
Touch and hold User‑defined command, decline call
Double tap earbud edge Volume up/down (Labs feature)

Customisation options:

  • Touch and hold assignment: Noise controls, Bixby, or volume pair
  • Noise control toggle: ANC and Ambient Sound
  • Labs feature: Enable "Double tap earbud edge" to control volume without using touch‑and‑hold slots

Touch behaviour can be tuned per side in the Galaxy Wearable app, letting users optimise between media transport, noise‑mode switching, and voice assistant access.

  • Water resistance: IPX7 (earbuds only), rated for submersion up to 1 m for 30 minutes
  • Important limit: Charging case is not water resistant
  • Firmware updates: Galaxy Wearable > Earbuds settings > Earbuds software update > Download and install
  • Cleaning guidance: Remove ear tips first and clean mesh/air duct with dry soft tools only
  • Connection best practice: Keep paired device within about 10 m and minimise RF obstruction/interference

Comfort and posture tools:

  • Earbud Fit Test: Built‑in check to improve seal quality and ANC performance
  • Neck stretch reminder: Sensor‑based posture reminder feature

Proper fit and routine cleaning are central to stable ANC, clear calls, and consistent acoustic output over long‑term use.
