• Dimensions & Weight: Earbuds: approx. 30.9 x 18.1 x 19.6 mm, 5.1g each. Charging case: 51 x 28.3 x 51 mm, ~44.3–45.1g.

Audio Quality and Features
• Drivers: Advanced 2-way speaker system per earbud — larger 11mm super-wide woofer (about 20% bigger diaphragm than predecessors) for deep, impactful bass and rich midtones + 5.5mm planar tweeter for crisp, detailed highs. Dual dedicated amplifiers (one per driver) minimize distortion and enhance clarity/power.
• Hi-Res Audio: Supports up to 24-bit / 96 kHz via Samsung Seamless Codec Ultra High Quality (SSC UHQ). Upscales lower-quality sources (e.g., MP3s, CDs, videos) for better detail and dynamics. Also supports SSC (scalable for stability), AAC, SBC, and LC3 (with Auracast).
• Sound Tuning: Warm, balanced profile with strong bass extension, clear vocals, and wide soundstage. 9-band customizable EQ + Adaptive EQ that adjusts based on ear shape/fit.
• 360 Audio: Immersive surround sound with head tracking for a theater- or concert-like experience.
• Other Audio: Dolby Atmos support, Adaptive EQ 2.0, Volume EQ.45
Noise Cancellation and Ambient Modes
• Adaptive Active Noise Cancellation (ANC) 2.0: Real-time processing that adapts to your ear shape, fit, and environment for more effective blocking of low- and high-frequency noise.
• Adaptive Noise Control: Automatically adjusts ANC/Ambient levels based on surroundings (e.g., quieter in a café, more aware outdoors).
• Voice Detect / Siren Detect: Automatically pauses music and switches to Ambient mode during conversations or emergency sirens.
• Ambient Sound: Transparent mode for hearing your surroundings clearly.

Call Quality
• Microphones: 6 total mics (3 per bud) with Voice Pickup Unit (VPU), high signal-to-noise ratio, and Deep Neural Network (DNN) for isolating your voice.
• Super Clear Calls: Super Wideband (SWB) audio up to 16 kHz + HD Voice technology for natural, clear conversations even in noisy environments. Best performance on compatible Galaxy devices.
Controls
• Touch Controls: Pinch gestures — single (play/pause or answer/end call), double (next track), triple (previous), pinch & hold (customizable preset or decline). Swipe up/down on stem for volume.
• Head Gestures: Nod to accept calls, shake to decline (or interact with Bixby/AI on supported One UI versions).
• App Integration: Controlled via Galaxy Wearable app or directly through One UI 8.5 Quick Panel/settings on newer Galaxy devices. No separate app needed for full Galaxy ecosystem access.

Battery Life
• Earbuds: Up to 6 hours music playback with ANC on / 7 hours with ANC off.
• Total with Case: Up to 26 hours (ANC on) / 30 hours (ANC off).
• Talk Time: Up to 4.5 hours (ANC on) / 5 hours (ANC off); total up to 20–22 hours.
• Battery Capacity: 61 mAh per earbud, 530 mAh in case.
• Charging: USB-C wired + wireless charging support for the case (charger/pad sold separately). Quick charging available. Actual times vary with usage, volume, codecs, and features.

Connectivity and Smart Features
• Bluetooth: Version 6.1 with LE Audio, Auracast broadcast support, and profiles including A2DP, AVRCP, HFP.
• Seamless Galaxy Integration: Auto Switch between paired Galaxy devices (phone, tablet, watch, etc.) on the same Samsung account. Easy pairing by opening the case.
• Galaxy AI Features (best on Galaxy devices with One UI 6.1.1+):
◦ Interpreter / Live Translate: Real-time translation (up to 22 languages) heard through the buds or read on screen.
◦ Voice-ready AI assistant (Bixby or others): Hands-free commands for notes, reminders, recipes, etc.
◦ Neck stretch reminder and other wellness alerts.
• Sensors: Accelerometer, gyro, hall, pressure, proximity, touch, VPU.

Compatibility
• Full Features: Optimized for Samsung Galaxy devices (S23/S24/S25/S26 series, Z Fold/Flip, Tab S series, etc.) running One UI 6.1.1 or later. UHQ audio, SWB calls, 360 Audio with head tracking, full AI, and Adaptive features shine here.
• Other Devices: Works via standard Bluetooth on Android, iOS, Windows, etc., but with limitations (e.g., max 16-bit/44.1 kHz audio, basic ANC/Ambient, no UHQ or advanced AI).

What’s in the Box

• Charging case
• 3 pairs of silicone ear tips (S/M/L)

Key Improvements Over Galaxy Buds3 Pro
• Upgraded 2-way drivers with dual amps for richer, more refined sound (deeper bass, clearer highs, less distortion).
• Better IP57 rating (vs. lower on prior models).
• Enhanced Adaptive ANC 2.0 with real-time adaptation.
• Refined metal design, slightly improved battery, and newer Galaxy AI integrations.
• More balanced/warm sound signature with customizable 9-band EQ.

The Galaxy Buds4 Pro excel for Samsung Galaxy users seeking top-tier sound, strong ANC, clear calls, and seamless AI integration in a comfortable, premium package. Non-Samsung users still get solid performance but miss some advanced codecs and features. Battery life is competitive but not class-leading compared to some rivals.
