Beyond gestures, the Buds 4 Pro introduces a suite of technical refinements that cater to audiophiles and productivity-driven users. The most noticeable upgrade lies in its dual-driver architecture, pairing a dedicated 12mm woofer with a 10mm tweeter to deliver a more precise soundstage. This setup reduces distortion in bass-heavy tracks while maintaining clarity in high frequencies—a critical improvement for users who demand studio-like fidelity from wireless earbuds.
The ANC 2.0 system takes a more adaptive approach, with three modes: Optimized (balanced noise reduction), Deep (for high-noise environments), and Off (for immersive audio). Unlike previous generations, the Buds 4 Pro dynamically adjusts its noise-canceling strength based on ambient conditions, making it more effective in transitional spaces like airports or co-working hubs. For users who rely on ANC for focus, this adaptability is a game-changer.
Advanced users will also appreciate the AI integration, which allows direct interaction with Bixby or other assistants without touching a device. Simply press and hold the earbud stem to activate voice commands, eliminating the need to unlock a phone. The Interpreter Mode further expands utility, offering real-time translation for up to 22 languages during calls—a feature that could be invaluable for travelers or multilingual professionals.
On the technical side, both models support HD Voice and 24-bit/96kHz audio, ensuring lossless playback for high-resolution files. The Pro model adds LPDDR5X RAM for faster processing of audio algorithms, contributing to smoother transitions between ANC modes and gesture commands.
For those who prefer tactile controls, the standard Buds 4 retain the engraved swipe zone on the stem, which provides better feedback than the Pro’s gesture system. The pinch-to-pause and tap-to-answer functions remain intuitive, though they lack the Pro’s adaptive responsiveness. The standard model also skips the AI chatbot access and Interpreter Mode, focusing instead on core ANC and audio performance.
Battery life remains a standout across both models, though the Pro’s additional features come at a slight cost. With ANC off, the Pro offers 7 hours of playback and 30 hours with the case, while the standard model delivers 6 hours and 30 hours, respectively. When ANC is active, both models see a roughly one-hour reduction in playback time. The Pro’s IP57 rating (vs. the standard’s IP54) also provides better protection against dust and water, though real-world durability will depend on usage patterns.
The charging case for both models features a transparent lid, allowing users to check battery levels at a glance. The Pro’s case includes a USB-C port, aligning with modern charging standards, while the standard model retains a micro-USB interface—a minor but notable distinction for users with fast-charging accessories.
Pricing reflects the feature divergence: the standard Buds 4 start at $179, while the Pro jumps to $249. For comparison, the Galaxy Buds 2 Pro (2022) was priced at $199, meaning the Pro model has seen a $50 increase—justified by its gesture controls, AI features, and upgraded ANC. Pre-orders are available now, with in-store releases scheduled for March 11.
For power users, the decision hinges on priorities. Those who value gesture control, AI integration, and premium audio will likely prefer the Pro. Meanwhile, users who prioritize battery life, tactile controls, and ANC without extra frills may find the standard model sufficient. Either way, Samsung has delivered a significant leap forward in wireless audio technology.
