If you want superior call clarity with a premium, reference-quality soundstage for long professional sessions, choose Technics Hi-Fi True; if you need adaptive noise cancellation that reacts to your environment and seamless AI integration for modern workflows, choose Samsung Galaxy Buds 4.
• Technics Hi-Fi True: Delivers industry-leading JustMyVoice technology with eight high-sensitivity microphones for unparalleled voice capture, paired with LDAC support for hi-res audio depth. Best for professionals who prioritize crystal-clear speech transmission over ambient isolation. - Samsung Galaxy Buds 4: Offers Adaptive Active Noise Cancellation 2.0 that intelligently adjusts in real-time, plus a dual-driver 2-way speaker system for rich highs and deep lows. The trade-off is its tighter ecosystem dependency for full AI functionality and specific codec support. Best for users immersed in a smart device ecosystem who demand versatility and environmental control.
The Technics Hi-Fi True earbuds are engineered for the person who treats their audio gear as a serious tool rather than just an accessory. If you spend hours on Zoom calls or virtual meetings where being misunderstood is not an option, these buds address the most common pain point in remote work: poor microphone quality. The design centers around the JustMyVoice technology, which utilizes eight high-sensitivity MEMS microphones alongside advanced noise reduction algorithms. This isn't just about blocking out background noise; it is about isolating your voice so clearly that you never have to repeat yourself or ask a colleague to turn down the volume on their end.
For the audiophile who also happens to be a heavy conference caller, the internal architecture offers a compelling mix. The 10mm free-edge dynamic driver and unique acoustic structure are built to deliver reference-quality audio with genuine depth and texture. When you switch from a work meeting to listening to high-resolution music files, the experience remains consistent because the hardware supports LDAC compatibility. This allows for wireless transmission of hi-res audio data at approximately three times the speed of conventional codecs, ensuring that the nuance in your favorite tracks is preserved without compression artifacts.
However, this product is not for everyone. If your primary use case involves commuting through noisy subways or working in chaotic open offices where silence is paramount, the lack of a specified adaptive ANC system might leave you wanting more. Additionally, the reliance on a precise fit means you must ensure the earpiece size matches your anatomy perfectly; a loose seal compromises both the acoustics and the effectiveness of the voice isolation.

This earbud is ideal for the corporate professional, the content creator, or the student who needs to record lectures or participate in online classes. The 3-device multipoint connectivity allows you to seamlessly switch between your laptop, phone, and tablet without manual re-pairing. You can receive a call on your computer, then instantly jump to your phone, all while maintaining the connection. The wireless charging case, compatible with Qi standards, keeps your desk clutter-free, but the focus remains squarely on audio fidelity and vocal clarity above all else.
The Samsung Galaxy Buds 4 Pro targets a different demographic entirely: the tech-forward user who lives in a connected world and values adaptability. These earbuds are designed for someone who wants their audio gear to actively manage their environment rather than just passively transmit sound. The standout feature here is the Adaptive Active Noise Cancellation 2.0. Unlike static noise filters, this system intelligently adapts in real-time to provide stronger, smoother noise cancellation wherever you go. Whether you are walking past construction sites, sitting in a busy coffee shop, or flying in a cabin, the buds adjust their filtering logic automatically to maintain a quiet listening space.
Beyond noise control, the audio performance relies on a sophisticated two-way speaker system. By incorporating both a tweeter and a woofer within each bud, the design aims to cover the frequency spectrum more effectively than single-driver alternatives. This separation ensures rich highs without distortion and deep, full lows that add weight to bass-heavy tracks. For those using spatial audio headphones for zoom calls or immersive media consumption, this hardware setup promises a wide soundstage and detailed instrument separation that feels expansive.
The integration of artificial intelligence into the daily workflow is another defining characteristic. When paired with compatible devices like the Galaxy S26 Series, these earbuds offer hands-free AI assistance. You can request quick answers or access real-time translations directly through your ears, turning a simple conversation into a multilingual interaction without needing to pull out your phone. This level of utility makes them a powerful tool for travelers or international business professionals who need language support on the fly. Furthermore, the IP57 rating provides peace of mind against rain and dust, making them durable enough for intense workouts or unpredictable weather conditions.
That said, the experience is deeply tied to the Samsung ecosystem. While the core audio and call features function well on Android generally, the full suite of AI capabilities and optimized comfort features are best realized when paired with specific Samsung smartphones. If you are invested in a non-Samsung Android or iOS environment, you will still get great sound and solid battery life, but the "AI assistant in your ear" and some of the adaptive nuances may not reach their full potential. The design also emphasizes an ear-hugging shape with changeable tips, suggesting a focus on long-term wearability, though the specific dimensions are not listed in the available data.
This product fits the mobile power user, the traveler, and the early adopter who wants their gadgets to do more than just play music. The ability to handle live translation and adaptive noise management makes it a versatile companion for a dynamic lifestyle. However, if you strictly prioritize raw vocal isolation for professional broadcasting or recording without the need for environmental smoothing, the heavy reliance on ecosystem-specific AI features might feel like unnecessary complexity.

After weighing the specifications and intended use cases, I would buy the Technics Hi-Fi True if my primary goal was to secure perfect audio quality for zoom calls. The engineering behind the JustMyVoice technology and the eight-microphone array addresses the single biggest frustration in remote communication: being heard clearly. While the Samsung option offers incredible adaptability and a cool AI factor, nothing beats the specialized vocal isolation that Technics has built into the EAH-AZ80-S. For a professional setting where every word matters, the Technics solution is the more focused and reliable choice.
Both models excel here but differently; Technics uses 8 mics and JustMyVoice to isolate your voice specifically, while Samsung uses Adaptive ANC 2.0 to dampen the surrounding environment in real-time.
Technics works universally with its multipoint connection and app control, whereas Samsung Galaxy Buds 4 unlock full AI and translation features only when paired with compatible Galaxy S-series devices.
The Samsung Galaxy Buds 4 Pro hold an IP57 rating, making them resistant to water and dust for life on the go, whereas the Technics sheet focuses more on fit stability and audio fidelity without specifying an IP rating.
Yes, both support high-resolution audio protocols; Samsung uses a 2-way speaker system for spatial-like immersion, while Technics supports LDAC for hi-res wireless transmission that enhances the sense of space in audio.
