  • 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 focused on 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 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 is tuned to reduce ear-canal pressure and improve long-session stability, while the matte texture helps grip and visual durability in daily 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 optimisation: Galaxy Earbud Fit Test in 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 under compatible Galaxy conditions.

  • ANC: Intelligent Active Noise Cancellation
  • Ambient mode: Ambient Sound (keeps environmental awareness without removing 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 needed, 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 extends practicality for full-day 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 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 strongest feature set inside Samsung's software stack, where codec switching, device handoff, find-my tools, and AI translation are deeply 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 consuming touch-and-hold slots

Touch behaviour can be tuned per side in Galaxy Wearable, allowing users to 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.
