Samsung Galaxy Buds2 Pro vs Technics AZ100: Which Premium Earbuds Should You Buy?

The world of premium true wireless earbuds has become incredibly competitive, with manufacturers pushing the boundaries of what's possible in these tiny packages. Today we're comparing two standout options that take notably different approaches to audio excellence: the Samsung Galaxy Buds2 Pro and the Technics Reference Class AZ100.

Both earbuds launched in the premium segment—the Samsung Galaxy Buds2 Pro in 2022 and the Technics AZ100 in early 2025—but they represent distinctly different philosophies. Samsung focused on tight ecosystem integration and consumer-friendly features, while Technics prioritized audiophile-grade sound quality and universal compatibility. At the time of writing, both command premium prices, though the newer Technics model typically costs more due to its advanced technology and recent release.

Understanding Premium True Wireless Earbuds

Before diving into the comparison, it's worth understanding what makes earbuds "premium." These aren't just wireless versions of basic headphones—they're sophisticated audio computers packed into packages smaller than a grape. Premium models typically include active noise cancellation (ANC), which uses microphones and processing to actively cancel out background noise, and support for high-quality audio codecs that preserve more detail than standard Bluetooth audio.

The key performance areas that separate good earbuds from great ones include sound quality, noise cancellation effectiveness, battery life, comfort, and call quality. Premium models also offer advanced features like spatial audio (which creates a surround-sound effect) and multipoint connectivity (connecting to multiple devices simultaneously).

Sound Quality: Two Different Approaches to Audio Excellence

The most fundamental difference between these earbuds lies in their audio philosophy, and it's immediately apparent when you listen to them.

The Samsung Galaxy Buds2 Pro delivers what audio engineers call a "warm" sound signature. This means they emphasize bass frequencies, making kick drums punch harder and adding richness to lower-pitched instruments. Samsung achieves this with a clever coaxial driver design—essentially two speakers in one housing. The larger 10mm woofer handles bass and midrange frequencies, while a smaller 5.3mm tweeter takes care of the highs. This setup allows for better frequency separation than single-driver designs.

What makes this particularly interesting is Samsung's proprietary audio codec called Samsung Seamless Codec (SSC). When paired with compatible Galaxy devices, this codec can transmit 24-bit audio—significantly more data than standard 16-bit audio. Think of it like the difference between standard definition and 4K video: more information means more detail and nuance in your music.

The Technics AZ100, however, takes a completely different approach. These earbuds use what Technics calls "magnetic fluid driver" technology, which sounds like science fiction but has real-world benefits. The driver uses a special oil containing magnetic particles between the magnet and voice coil (the part that actually moves to create sound). This allows for incredibly precise control over the driver movement, resulting in lower distortion and more accurate sound reproduction.

Where the Samsung Galaxy Buds2 Pro colors the music to make it sound more exciting, the Technics AZ100 aims to reproduce exactly what the artist and sound engineer intended. This neutral approach means you'll hear more detail in complex orchestral pieces and better instrument separation in dense rock mixes. The frequency response extends from 20Hz to 40kHz—well beyond human hearing range—which contributes to a more natural sound.

For most listeners, the choice comes down to preference. If you primarily listen to genres like hip-hop, EDM, or pop music, the Samsung Galaxy Buds2 Pro's bass emphasis will make your music sound more engaging and fun. But if you're a critical listener who enjoys classical music, jazz, or acoustic recordings, the Technics AZ100's accuracy will reveal details you've never noticed before.

Noise Cancellation: Blocking Out the World

Both earbuds offer active noise cancellation, but their implementations reveal interesting engineering differences.

The Samsung Galaxy Buds2 Pro uses six microphones total—three on each earbud—to monitor outside noise and generate opposing sound waves to cancel it out. Samsung claims about 30dB of noise reduction at 100Hz, which is impressive for the low-frequency rumble of airplane engines or air conditioners. What's particularly clever is their "Voice Detect" feature, which automatically pauses noise cancellation and switches to ambient mode when you start talking, then switches back after you stop.

The Technics AZ100 takes a more sophisticated approach with what they call "Adaptive Noise Cancelling." Instead of using a fixed algorithm, it continuously analyzes your environment and adjusts the cancellation in real-time. It even adapts to your individual ear shape, since everyone's ears create different acoustic environments. This results in more consistent noise cancellation across different situations.

From our research of user experiences, the Technics AZ100 tends to perform better in challenging environments like busy coffee shops or open offices, where noise patterns constantly change. The Samsung Galaxy Buds2 Pro excels in more predictable environments like flights or commutes.

Battery Life: Powering Through Your Day

Battery performance reveals one of the Technics AZ100's biggest advantages. While the Samsung Galaxy Buds2 Pro provides a respectable 5 hours of listening with ANC enabled (extending to 18 hours with the charging case), the Technics AZ100 nearly doubles that with 10 hours of continuous use and 28 hours total.

This difference matters more than you might think. If you're someone who frequently forgets to charge devices or travels regularly, those extra hours can mean the difference between having music on a long flight and sitting in silence. The Technics AZ100 also features faster quick charging—15 minutes provides 90 minutes of playback, compared to the Samsung's more modest quick-charge capabilities.

Connectivity: Playing Well with Others

Here's where the philosophical differences between these companies really show. The Samsung Galaxy Buds2 Pro offers incredible features—but only if you're using Samsung devices. The 24-bit audio, 360 Audio with head tracking, and automatic device switching all require a Galaxy phone or tablet running One UI 3.1 or later. It's a bit like buying a sports car that only runs on fuel available at one gas station chain.

The Technics AZ100, conversely, works equally well with any device. It supports the high-quality LDAC codec (which works with many Android devices), traditional AAC and SBC codecs for universal compatibility, and even the newer LC3 codec for future-proofing. Most impressively, it can maintain connections to three devices simultaneously, switching audio based on which device is actively playing music or receiving calls.

This multipoint connectivity is genuinely useful in real-world scenarios. Imagine listening to music on your laptop while working, then seamlessly switching to take a call on your phone, then jumping to a podcast on your tablet—all without manually disconnecting and reconnecting.

Advanced Features: The Future of Audio

Both earbuds offer spatial audio, but with different implementations. The Samsung Galaxy Buds2 Pro's 360 Audio creates an immersive soundstage that follows your head movements, making it feel like sound sources are positioned around you in 3D space. This works particularly well for movies and shows with Dolby Atmos soundtracks when using Samsung devices.

The Technics AZ100 includes similar spatial audio capabilities but adds AI processing that adapts the effect based on your listening environment and the content type. This means the spatial processing might be more subtle for music but more pronounced for movies—a smarter approach that prevents the effect from becoming distracting.

Call Quality: Staying Connected

Professional call quality has become increasingly important as remote work normalizes, and here the Technics AZ100 clearly excels. Its "Voice Focus AI" technology uses machine learning to distinguish your voice from background noise, making you sound clearer even in noisy environments. The system analyzes incoming audio in real-time, filtering out everything from keyboard clicking to air conditioning hum.

The Samsung Galaxy Buds2 Pro, despite having more microphones, struggles with call quality according to user feedback. The microphones pick up your voice adequately in quiet environments, but background noise often overwhelms the processing capabilities, making you difficult to understand during important calls.

Home Theater Considerations

For home theater use, both earbuds offer compelling but different advantages. The Samsung Galaxy Buds2 Pro excels when paired with Samsung TVs, offering low-latency audio and 360 Audio processing that can make movie dialogue and effects feel more immersive. The bass emphasis also adds impact to action scenes and music.

The Technics AZ100's neutral sound signature provides more accurate reproduction of movie soundtracks as directors intended, while the superior battery life means you won't need to pause for charging during long viewing sessions. The multipoint connectivity also allows you to seamlessly switch between your TV and other devices without reconnecting.

Comfort and Build Quality

Both earbuds prioritize comfort, but with different approaches. The Samsung Galaxy Buds2 Pro achieves an impressive 5.5 grams per earbud—remarkably light for the feature set. They're also 15% smaller than Samsung's previous flagship model, making them nearly disappear in your ears during extended use.

The Technics AZ100 uses what they call a "concha-fit" design that follows the natural curves of your ear. While we don't have exact weight specifications, Technics claims they're 10% smaller and 16% lighter than their previous model. User feedback consistently praises their all-day comfort.

Both offer water resistance, though with different ratings. The Samsung Galaxy Buds2 Pro provides IPX7 protection (can withstand brief submersion), while the Technics AZ100 offers IPX4 (splash and sweat resistant). For most users, both provide adequate protection for workouts and weather.

Value Proposition and Market Positioning

At the time of writing, both earbuds command premium prices, but they target slightly different markets. The Samsung Galaxy Buds2 Pro offers exceptional value within Samsung's ecosystem, providing flagship features at a relatively accessible premium price point. However, much of their appeal evaporates if you're not using Samsung devices.

The Technics AZ100 positions itself as a reference-quality audio product that happens to be wireless, similar to how high-end wired headphones are marketed to audiophiles. The premium pricing reflects the advanced driver technology and universal compatibility, making it a better long-term investment for users who switch between different device brands.

Who Should Choose What

The decision ultimately comes down to your priorities and device ecosystem.

Choose the Samsung Galaxy Buds2 Pro if you're deeply integrated into Samsung's ecosystem and want the seamless experience that comes with it. They're perfect for users who prioritize bass-heavy music genres, value compact design, and appreciate features like automatic device switching between their Galaxy phone, tablet, and watch. The 360 Audio recording feature also makes them appealing for content creators using Samsung devices.

The Technics AZ100 makes more sense for users who prioritize pure audio quality, use multiple device platforms, or need professional-grade call quality. They're the better choice for audiophiles, frequent travelers (thanks to superior battery life), and business professionals who live on video calls. The universal compatibility also makes them a safer long-term investment if you're not sure what devices you'll be using in the future.

The Verdict

While both earbuds excel in their intended roles, the Technics AZ100 emerges as the more technically accomplished product. The magnetic fluid driver technology, adaptive noise cancellation, superior battery life, and universal compatibility create a more compelling package for most users.

However, the Samsung Galaxy Buds2 Pro shouldn't be dismissed. For Samsung ecosystem users, they provide excellent value and integration that the Technics simply can't match. The warm sound signature also appeals to mainstream music preferences in a way that the Technics' neutral approach might not.

Your choice should align with your priorities: ecosystem integration and fun sound signature with Samsung, or technical excellence and universal compatibility with Technics. Either way, you're getting a premium audio experience that would have been impossible just a few years ago.
