Samsung Unveils All New Galaxy Buds4 Series

Samsung Electronics Co., Ltd. today introduced its latest Galaxy Buds4 Pro and Galaxy Buds4, redefining what premium earbuds can deliver in both superior Hi-Fi  audio and everyday wearability. Built to sound as good as they feel, the Galaxy Buds4 series pairs exceptional sound quality with a more refined, computationally designed fit, bringing Samsung’s most advanced audio and wearability innovations together in one seamless experience. For the first time, Galaxy Buds4 Pro features a wider woofer, combined with enhanced Active Noise Cancellation (ANC) and an enhanced Adaptive Equaliser (EQ), to supply full-spectrum sound true to the original recording — while intelligently adapting to real-world conditions. Thoughtful design updates, intuitive hands-free controls, and deeper AI integration further underscore Samsung’s commitment to earbuds designed for how people listen, move, and live throughout the day.

“Most of us now use our earbuds for everything – the commute, the gym, back-to-back calls or blocking out noise while we work,” said Annika Bizon, Vice President of Product and Marketing for Mobile Experience at Samsung UK and Ireland. “The Galaxy Buds4 series are designed to be the one pair you don’t have to swap out. They combine Hi-Fi sound with a fit that’s comfortable enough for all-day wear and intelligent features that adapt to whatever you’re doing in that moment.”

Computational Design Optimised for Enhanced Stability and All-Day Comfort

With the Galaxy Buds4 series, Samsung establishes an iconic Buds blade design, a computational design achievement based on hundreds of millions of global ear data points and over 10,000 simulations. The Galaxy Buds4 series features an ultra-sleek, ergonomic fit with smaller, better-fitting earbud heads to deliver a more secure, comfortable experience during all-day wear. The new stabilised blade includes a premium metal finish and an engraved pinch control[4] area to help users easily locate and adjust settings. Additionally, the new transparent clamshell-type cradle makes storage and charging more intuitive and convenient — while also highlighting the refined blade design to deliver a stylish, high-quality listening experience on the go.

Galaxy Buds4 Pro and Galaxy Buds4 offer distinct design architectures to meet different needs. Galaxy Buds4 Pro features a canal-fit design that combines ultimate sound with maximum functionality. The open-fit design of Galaxy Buds4 delivers a comfortable, user-friendly audio experience. Customers also have the option to choose from several distinct colourways, with Galaxy Buds4 Pro and Galaxy Buds4 available in White and Black with a refined matte finish — as well as a Samsung.com exclusive Pink Gold for Galaxy Buds4 Pro.

Superior Hi-Fi Sound with Innovative Hardware Updates

Galaxy Buds4 Pro introduces a new wider woofer, featuring a new design that makes efficient use of space. By maximising the vibration area and minimising the speaker’s edge, the wider woofer increases the effective speaker area by almost 20% compared to the previous generation without sacrificing wearability. Combined with the tweeter, these features deliver natural, immersive audio with clean bass and rich treble that supports 24-bit/96kHz audio— ultimately delivering high-fidelity sound true to the original recording. These hardware enhancements capture everything from the high, resonant sounds of violins to the deep, throaty pulses of double basses — details that were difficult to reproduce in earlier generations. The two-way speaker is strategically placed on the upper side of the metal finish to maximise Active Noise Cancellation functionality, while minimising feedback from wind and other external factors.

Maximised Audio Experiences with Enhanced Adaptive EQ and ANC

Galaxy Buds4 series offers software updates that build on powerful adaptive sound capabilities users have come to love in previous Galaxy Buds generations. Enhanced ANC can tune out everything from heavy transit sounds to everyday background noise, ensuring an immersive audio experience that adapts to changing environments. For example, when commuting on a bus, train or airplane, Galaxy Buds4’s enhanced Active Noise Cancellation reduces low-frequency engine and road noise while maintaining rich, balanced sound — allowing users to focus on music, podcasts or calls without distraction.

Enhanced Adaptive ANC/EQ allows for full media immersion, minimising noise leakage by analysing the wearing conditions and unique ear shape of each user. Alongside dynamic frequency adjustments, this feature applies optimal ANC algorithms in real time for peak noise-cancelling performance so users can enjoy fine-tuned sound experiences tailored to their individual needs.

When it’s time to make a phone call, Super Clear Call utilises super wideband call technology and machine learning models trained for noise reduction and voice enhancement to provide ultra-clear call quality and double the bandwidth of conventional Bluetooth calls. Whether users are cheering at a football game, dining in a bustling restaurant, or spending time with their children at the playground, their voice remains crisp and clear, ensuring they sound as if they were speaking face-to-face.

An Enriched Galaxy Ecosystem Experience

For Galaxy users, the Galaxy Buds4 series introduces integrations that enhance the Galaxy ecosystem experience. Users can initiate AI agents including Bixby, Google Gemini and Perplexity — with hands-free and voice controls, helping users stay engaged with their surroundings while maintaining control over their audio experience. Galaxy Buds4 Pro allows users to access AI features without reaching for their phones, making it easier to integrate AI into their everyday routines.

Galaxy ecosystem users can enjoy simple Galaxy Buds setup. Just by opening the cradle — without having to install the Galaxy Wearable app — Samsung users can easily connect their Galaxy Buds to their phone or tablet. Through the Galaxy Buds shortcut menu or in the Quick Panel, users can control and customise the volume or EQ for the optimal sound experience.

Galaxy Buds4 Pro also includes Head Gesture controls to manage calls and engage with Bixby, allowing users to perform subsequent actions hands-free. Along with voice commands, hands-free controls such as these allow users to navigate their day without distraction, ensuring their daily activities remain seamless and uninterrupted.

The Galaxy Buds4 series is available for pre-order from February 25th, with general availability starting March 11.

Galaxy Buds4 Pro is available for RRP €259 , with Galaxy Buds4 RRP €189. Customers who pre-order Samsung Galaxy S26 Series will receive 10% off the new Galaxy Buds4 Series from Samsung.com.

ugee FreSound Inspiration Open-Earbuds Review

The Ugee FreSound Inspiration Open-Earbuds  provide comfortable, all-day audio that keeps you connected to your environment. These earbuds have no ANC like any Open-Ear earbuds but thes look great and come in a really nice case and looks like a premium product out of the box.

These are comfortable, Utilizing an open-ear, air-conduction design, the FreSound rests lightly on the outside of your ear, delivering sound without blocking the ear canal. This eliminates the pressure, discomfort, and ‘stuffed-up’ feeling associated with traditional in-ear models.

At just 8.7 grams per earbud, they are exceptionally lightweight. The key to their stability is the flexible, full-wrap liquid silicone ear hook, which feels soft and skin-friendly. They stay securely in place during vigorous activities like running and gym workouts (assisted by an IPX5 sweat-resistant rating), making them a fantastic option for athletes who prioritize situational awareness.

The audio experience is dictated by the open-ear design, which delivers unique benefits and expected trade-offs.

  • Clarity and Detail: The FreSound has a 12mm high-amplitude driver and a custom-tuned frequency curve. It delivers excellent mid-range clarity and crisp highs. These earbuds particularly excel with podcasts, no tinny sound when maxed out on volume
  • Bass and Volume: As is typical for open-ear models, the bass is present—it’s tight and rhythmic enough to motivate a workout—but it lacks the deep, chest-thumping sub-bass found in sealed earbuds. This is normal for this style of earbud
  • Calling: Call quality is strong thanks to AI Call Noise Cancellation, which helps your voice cut through moderate background noise effectively.

The lack of a companion app or customizable EQ means you are reliant on the factory tuning, which some users find a bit too bright or sharp with certain amplified genres like rock and pop but overall they deliver decent audio and for me could use anytime.

The FreSound offers reliable, all-day power:

  • Single Charge: Up to 8 hours of continuous listening.
  • Total Playback: Up to 30 hours using the charging case.
  • Connectivity: Bluetooth 5.3 ensures fast pairing, stable connection, and minimal latency, which is appreciated when watching videos. The added multipoint connection feature for dual-device pairing is a convenient bonus.

The Ugee FreSound Inspiration Open-Earbuds are a compelling choice for a specific audience. They successfully deliver a perfect balance between audio enjoyment and environmental awareness, making them an ideal daily driver for safety-conscious users, fitness enthusiasts, and professionals who need to hear colleagues or surroundings while they work.

They trade deep bass and noise isolation for unparalleled comfort and safety. While the sound tuning might be divisive for heavy rock listeners, their secure fit, great battery life, and clear mid-range make them a strong, budget-friendly contender in the growing open-ear category.

These are ideal forRunners, cyclists, commuters, and people who find traditional in-ear buds uncomfortable and want the best of both worlds hearing what is going on around them and they deliver here with this and adio in general. Check the video below for a detailed look.

 

Features

  • Seamless Comfort: Our Inspiration Open Earbuds use full-wrap liquid silicone for a soft, ergonomic fit all day.
  • Open-Ear Design: OWS open-ear headphones deliver great audio while keeping you aware outdoors or on the go.
