Samsung is effectively narrowing the distance with its leading competitors in wireless headphone sales. The achievement represents an important advancement because Samsung which operates as a major technology company has struggled to compete with specialized companies in delivering superior sound results.
The company developed the IconX series as its first wireless headphones which it released in 2016. The company developed its wireless headphone system before Sony and Bose entered the market with their main products. The company developed its wireless headphone system before Sony and Bose entered the market with their main products which created a gap between their audio quality and phone products.
Expert reviewers frequently acknowledged Sony and Bose as superior products whereas the early Galaxy Buds models received average ratings and weak evaluations.
The major shift occurred in 2023 when the Galaxy Buds 3 Pro became available to consumers. The current generation which brought new design elements and additional features completely transformed the sound performance of the product. Samsung introduced 24-bit/96kHz hi-res codec support to the public which enables users to experience high-quality sound that matches the standards of top-tier products.
The Galaxy Buds 4 Pro launches as the best version of the product after its preceding successes. Samsung made design improvements for its products based on user feedback by taking away unneeded parts which included “blade” lights and switching to a premium metal exterior. The engineers built better audio systems through their work on dual speaker and dual amplifier systems which resulted in higher audio detail and better sound performance. The Buds 4 Pro’s music reproduction capabilities which set a new company record produce better sound results because of their ability to handle classical music tracks and pop music tracks.
The Samsung audio system is close to winning because the Sony WF-1000XM6 Republic of Music and Apple AirPods Pro 3 show excellent performance. The Buds 4 Pro demonstrate Samsung’s dedication to audio quality because they show major progress from their previous models which offered subpar performance. The next phase of Samsung’s development strategy will use Galaxy AI to design unique features which will distinguish them from their competitors. Apple and Technics demonstrate that even when smart features appear attractive, the essential requirement for complete excellence remains sound quality. The current sound system of Samsung which they developed for their fourth generation products will enable them to compete with Sony and Apple in the upcoming years.
The contemporary design of the product displays modernity and fashion. The company chose to create its charging case design as an upright square box which features a transparent plastic lid that creates the appearance of an advanced jewelry display. The transparent lid enables users to see the earbuds which are organized inside without needing to open the container.
The entire charging case exhibits exceptional craftsmanship. The bottom section uses matte plastic to create a surface that prevents fingerprint marks whereas the flat base displays embossed details together with a Type-C charging connection and a user-friendly pairing button which is located at the rear.
The most important and impressive development occurs in the new design of both the housing and stem components. Samsung has made the daring decision to replace its traditional round design with a new elongated stem design. The stem of the device includes a rounded shape which displays a distinct flat bevel design together with a metallic strip that extends across the entire earbud body.
The earbuds create a feeling of advanced design which combines strength and high-end quality because their appearance differs from all other products that competitors produce in the current market.
I find the Samsung Galaxy Buds 4 Pro to be slightly more comfortable to wear than its predecessor. The housing design uses ergonomic principles to create a comfortable fit because its soft rounded edges form a secure seal with the ear canal. The weight of each earbud amounts to 5.3 grams which makes them one of the lightest earbuds available. The included silicone eartips provide superior retention because they create a secure fit which blocks external sounds while maintaining earbud stability during intense workouts and running sessions.
The earbud design features a flat tapered body which provides both aesthetic appeal and practical benefits. Users can squeeze to pause/play music and swipe up and down along the metal strip to adjust the volume with extreme precision, rarely accidentally touching the wrong button. The IP57 water resistance rating for the earbuds allows users to exercise without worry about sweat and unexpected rain showers. Multiple feature improvements have occurred but the ecosystem barrier continues to block progress.
The Samsung Galaxy Buds 4 Pro can be considered a pioneer in bringing advanced AI features to True Wireless earbuds. The Galaxy Wearable app provides users with an exceptionally simple yet complete control system. The system allows users to manage noise cancellation, check earbud fit, and activate advanced features which include reading notifications aloud and displaying neck stretching reminders based on their downwards gaze duration.
Users will find the most advanced AI capabilities from their experience of Real-time Interpreter, which enables them to use two-way translation through their earbuds. The head gestures feature allows users to control their phone calls by nodding their head to accept calls and shaking their head to decline calls, all without needing to touch their earbuds. The system provides fast and precise responses, which enable users to perform their daily tasks with their virtual assistant that works through their earbuds.
Adaptive ANC 2.0 system achieves outstanding noise cancellation results because its AI technology enables it to assess both surroundings and ear canal seal quality. The earbuds are capable of removing both car engine sounds and office environment sounds through their active noise control features.
The Voice Detect and Siren Detect features function with high reliability. The earbuds will decrease music playback volume and switch to their most transparent mode when you begin speaking, before returning to their previous state after your conversation ends.
The Samsung ecosystem prevents me from using all AI functions and premium audio codecs that I dislike about this headset and its earlier version. The $230 headset becomes useless to iPhone and Xiaomi and OPPO users because they cannot access its essential functions. The system will not provide AI translation, users cannot control their devices through nodding and shaking head movements, and hands-free Bixby and Gemini assistant calling features will not function. The SSC UHQ 24-bit/96kHz codec will not be available to users. Samsung has created a highly controlled ecosystem system which restricts non-Samsung customers from accessing their products.
The sound quality of Samsung Galaxy Buds 4 Pro functions as the essential component which determines the overall evaluation of this product. The company implemented a substantial hardware enhancement by installing a dual-driver system which consists of an 11mm woofer and a 5.5mm planar diaphragm tweeter. The main feature of this product exists because every driver receives power from its dedicated amplifier which results in reduced distortion while achieving exceptional audio clarity across different frequency ranges.
The bass performance of these headphones shows powerful capabilities when listening to energetic music genres which include EDM and Hip-Hop. The impact maintains its solid characteristics because the deep sub-bass produces resonant sounds which the large woofer efficiently controls. The bass delivers a clean and punchy sound which maintains balance without creating a muddy effect throughout the mid-range frequencies. The sound signature of the current Samsung Galaxy Buds provides a substantial improvement over the previous generation which used a conventional sound signature.
The mid and treble ranges are masterfully executed throughout the entire spectrum but become most visible during acoustic and vocal performances. The singer’s voice is brought forward with high clarity, smoothness, and no harshness. The planar diaphragm reproduces instrument sounds such as guitar string plucking and cymbals with sharpness and smoothness. The soundstage expands beyond normal limits which produces a spacious experience that creates deep 3D depth perception when users enable the 360 Audio surround sound feature.
The Wearing app provides an advanced 9-band equalizer (EQ) which enhances music listening through its software capabilities and its hardware requirements. The users have the ability to create their own unique audio profiles by selecting from preset options which include Bass Boost and Clarity and Dynamic, or they can use the frequency sliders to create their desired audio settings.
Samsung Galaxy Buds 4 Pro Battery Life
Samsung provides its premium earphone model with a battery capacity which performs adequately for typical usage but does not reach high levels. The earphones provide up to 7 hours of continuous music playback with ANC enabled. The total time for usage reaches about 30 hours when you add the charging case which represents the common duration found in premium True Wireless earphones available today.
The Samsung Galaxy Buds 4 Pro assessment I conducted shows that the product meets all of the commitments made by the manufacturer. I set the volume to 70% and switched on ANC with Compatibility mode. I streamed music through Spotify. The earbuds continued working for more than 6 hours until the battery reached its lowest point. This battery life provides sufficient power to support a complete workday at the office combined with a demanding workout and an entire domestic flight.

Are the Samsung Galaxy Buds 4 Pro worth buying?
The Samsung Galaxy Buds 4 Pro review demonstrates that Samsung has developed a remarkable hardware product. The flat metal design provides a trendy look and excellent ear grip, the clear two-way sound satisfies most music lovers, and the ANC noise cancellation and intelligent transparency system work extremely smoothly. The main product limitation exists because Samsung designed their ecosystem system to require users to purchase their ecosystem headphones for complete product functionality.
This product remains a valuable choice because it provides essential features for Samsung smartphone users. The combination delivers an advanced user experience which produces excellent audio performance.
