Premium True Wireless Earbuds: Samsung Galaxy Buds 3 Pro vs Technics AZ100

The premium true wireless earbud market has exploded in recent years, with manufacturers pushing the boundaries of what's possible in these tiny audio devices. At the time of writing, buyers face an interesting choice between two very different approaches to premium audio: the Samsung Galaxy Buds 3 Pro, which launched in 2024 with a focus on practical excellence and ecosystem integration, and the Technics AZ100, released in 2025 as a reference-class offering for serious audio enthusiasts.

Understanding what separates premium earbuds from their budget counterparts is crucial for making an informed decision. These products justify their higher prices through advanced driver technology, sophisticated active noise cancellation systems, superior microphone arrays for calls, extended battery life, and smart features that adapt to your listening habits. The question isn't whether these earbuds sound good—they all do—but rather which approach to premium audio best matches your priorities and lifestyle.

The Two Philosophies: Practical Excellence vs Technical Mastery

The Samsung Galaxy Buds 3 Pro represents Samsung's most mature approach to premium earbuds yet. After years of refining their formula, Samsung adopted a new stem-based design in 2024 (similar to Apple's AirPods Pro) while focusing intensely on the features people actually use daily: crystal-clear phone calls, excellent noise cancellation, and seamless integration with modern digital life.

The Technics AZ100, launching in 2025, takes a different path entirely. Technics, with their legendary reputation in high-end audio equipment, engineered these earbuds as miniature reference monitors. They're targeting the listener who wants to hear every detail in their music, even if it means sacrificing some convenience features along the way.

At the time of writing, the Samsung Galaxy Buds 3 Pro commands a significantly lower price than the Technics AZ100—nearly $100 less in many markets. This price difference reflects their different target audiences and engineering priorities, but it also makes the value equation more complex than it first appears.

Sound Quality: Where Engineering Philosophy Becomes Audible

When evaluating premium earbuds, sound quality remains the most critical factor, but "good sound" means different things to different listeners. The Technics AZ100 and Samsung Galaxy Buds 3 Pro represent two distinct approaches to achieving premium audio.

Technics AZ100: The Audiophile's Choice

The Technics AZ100 employs proprietary magnetic fluid drivers—a technology that uses an oil-like substance with magnetic properties positioned between the driver magnet and voice coil. This isn't just marketing speak; magnetic fluid drivers offer genuine technical advantages. The fluid helps dampen unwanted vibrations while allowing the voice coil to move more precisely, resulting in lower distortion and more accurate sound reproduction.

In practice, this translates to what many describe as a "veil being lifted" from familiar music. Female vocals gain a crispness and presence that makes them sound more lifelike, while instruments like guitars and drums reveal subtle details that cheaper earbuds simply can't reproduce. The Technics AZ100 creates a three-dimensional soundstage where you can almost pinpoint where each instrument sits in the recording space.

The frequency response shows the Technics AZ100 delivers some of the heaviest bass among premium earbuds, with notable peaks at 1.4 kHz and above 7kHz. However, unlike bass-heavy consumer earbuds that sacrifice clarity, Technics maintains a darker background in the midrange frequencies that actually enhances detail perception. When listening to complex orchestral pieces or multi-layered electronic music, this approach allows individual elements to remain distinct even in busy passages.

The Technics AZ100 also supports Sony's LDAC codec, which can transmit audio at up to 990 kbps—roughly three times the data rate of standard Bluetooth audio. For listeners with high-quality source material, this means less compression and more of the original recording's nuance makes it to your ears.

Samsung Galaxy Buds 3 Pro: Engaging and Accessible

The Samsung Galaxy Buds 3 Pro takes a more universally appealing approach with their enhanced 2-way speaker system. This setup combines a 10.5mm dynamic driver handling lower frequencies with a 6.1mm planar magnetic tweeter for the highs—essentially creating a miniature version of high-end speaker systems.

Samsung's tuning philosophy creates what audio engineers call a "V-shaped" frequency response, where both bass and treble are elevated while midrange frequencies are slightly recessed. This might sound like a compromise, but it's actually quite clever. The V-shaped signature makes music feel more dynamic and exciting across a wide range of genres, from hip-hop to classical music.

The Samsung Galaxy Buds 3 Pro excels at creating what many describe as a "wide soundstage"—the sense that music is happening around you rather than just inside your head. This approach works particularly well for modern pop, electronic music, and movie soundtracks where impact and energy matter as much as technical accuracy.

Samsung's proprietary Seamless Codec can deliver 24-bit/96kHz audio quality, but only when paired with compatible Samsung devices. This ecosystem limitation is worth considering if you don't own recent Samsung hardware, as you'll be restricted to standard AAC and SBC codecs.

The Adaptive EQ feature uses Galaxy AI to analyze how the earbuds fit in your specific ears and adjusts the sound accordingly. This personalization means the earbuds can partially compensate for variations in ear shape and earbud positioning, potentially improving sound quality for users who might not achieve a perfect seal with traditional tuning.

The Verdict on Sound

For pure technical audio performance, the Technics AZ100 clearly leads. If you're the type of listener who notices subtle details in familiar recordings or appreciates the ability to pick out individual instruments in complex arrangements, Technics delivers that level of resolution. However, the Samsung Galaxy Buds 3 Pro offers a more immediately engaging presentation that works well across diverse music genres and listening situations.

Active Noise Cancellation: Silence as a Feature

Active noise cancellation (ANC) has become a must-have feature in premium earbuds, but not all implementations are equal. ANC works by using external microphones to detect ambient sound, then producing "anti-noise" through the earbuds' drivers to cancel out unwanted frequencies. The effectiveness depends on both the quality of the microphones and the processing algorithms.

The Samsung Galaxy Buds 3 Pro delivers what many consider best-in-class noise cancellation. Samsung's Adaptive ANC system uses Galaxy AI to continuously analyze your environment and adjust cancellation strength accordingly. This isn't just marketing—the system genuinely adapts to different noise profiles, whether you're on a plane, in a coffee shop, or walking on a busy street.

Samsung includes thoughtful features like Voice Detect, which automatically reduces music volume and activates transparency mode when it detects you speaking, and Siren Detect, which allows emergency vehicle sounds to pass through even with ANC enabled. These details show Samsung's focus on real-world usability.

The Technics AZ100 offers competent adaptive noise cancellation that adjusts to your environment and ear shape, but it doesn't match Samsung's overall effectiveness. In direct comparisons, more mid-range frequencies pass through the Technics system, meaning you'll still hear some background chatter and environmental noise that Samsung would eliminate.

For frequent travelers or anyone working in noisy environments, the Samsung Galaxy Buds 3 Pro provides a clear advantage in creating a quiet listening environment.

Call Quality: The Unsung Hero Feature

While most earbud reviews focus on music performance, call quality deserves serious consideration in our increasingly remote world. Here, the Samsung Galaxy Buds 3 Pro delivers a decisive victory that borders on unfair to the competition.

Samsung employs six microphones total (three per earbud) combined with a Voice Pickup Unit (VPU) and Super Wide Band call technology. The result is consistently clean, natural-sounding voice transmission even in challenging environments. The noise gating is aggressive enough to filter out wind and background noise without making your voice sound robotic—a common problem with overly processed call audio.

The Technics AZ100 includes Voice Focus AI, which applies noise filtering to both your outgoing voice and the incoming audio from the person you're calling. While this creates a cleaner overall call experience, the underlying microphone hardware doesn't match Samsung's performance in noisy environments.

If you frequently take calls while walking outdoors, in busy offices, or other challenging acoustic environments, the Samsung Galaxy Buds 3 Pro provides a significant practical advantage that justifies the purchase decision alone.

Connectivity: Managing Multiple Devices

Modern life requires juggling multiple devices, and premium earbuds need to handle these transitions gracefully. The Technics AZ100 introduces an industry-first feature: three-way Bluetooth multipoint connection. Most earbuds can connect to two devices simultaneously, but Technics allows seamless switching between your smartphone, laptop, and tablet.

This might seem like a minor feature, but it's transformative for productivity-focused users. You can be listening to music on your laptop, take a call on your phone, then switch to a video on your tablet without manually disconnecting and reconnecting each time. The Technics AZ100 also gives you control over whether devices switch automatically or require manual selection.

The Samsung Galaxy Buds 3 Pro offers standard two-device multipoint, but includes seamless switching within Samsung's ecosystem. If you own multiple Samsung devices, the earbuds can intelligently switch between them based on which device is actively playing audio.

Both earbuds support modern Bluetooth standards (5.4 for Samsung, 5.3 for Technics) with reliable connections, but Technics edges ahead for users managing complex device workflows.

Battery Life: Endurance vs Convenience

Battery performance involves two key metrics: how long the earbuds last on a single charge and total listening time with the charging case. The Technics AZ100 excels in single-charge endurance, delivering up to 12 hours of listening with ANC enabled—nearly double the Samsung Galaxy Buds 3 Pro's 6-7 hours.

For users who spend long days at the office or take extended flights, this difference is meaningful. The Samsung Galaxy Buds 3 Pro compensates somewhat with a higher-capacity charging case that provides more total listening time (26-30 hours vs Technics' 28 hours), but you'll need to return to the case more frequently.

Both earbuds support quick charging features, with 15-minute charges providing 90 minutes of playback on the Technics AZ100 and similar quick-charge capabilities on Samsung.

Fit, Comfort, and Durability

The Samsung Galaxy Buds 3 Pro adopts a stem-based design that distributes weight more evenly and generally provides better comfort for extended wear. At 5.4 grams per earbud, they're notably lightweight and include Samsung's "blade" control system that combines touch, swipe, and pinch gestures.

The Technics AZ100 uses a more traditional in-ear design with a deeper insertion that some users find uncomfortable. However, this deeper fit contributes to better passive noise isolation and prevents the earbuds from falling out during physical activity.

For durability, the Samsung Galaxy Buds 3 Pro carries an IP57 rating, protecting against both dust and water immersion up to one meter for 30 minutes. The Technics AZ100 only offers IPX4 water resistance with no dust protection, making Samsung more suitable for outdoor activities or dusty environments.

Home Theater and Movie Watching

Both earbuds include spatial audio features that enhance movie watching and gaming experiences. The Samsung Galaxy Buds 3 Pro supports 360 Audio with head tracking, creating an immersive surround sound experience when watching supported content. This works particularly well with Samsung TVs and devices for a seamless home theater experience.

The Technics AZ100 includes Dolby Atmos support with Dolby Head Tracking technology, which recalibrates audio as you move your head. For movie enthusiasts, both options provide engaging experiences, though Samsung's ecosystem integration might provide smoother operation if you're already using Samsung devices for your entertainment setup.

Making the Right Choice

The decision between these earbuds ultimately depends on your priorities and use patterns. The Samsung Galaxy Buds 3 Pro represents the better choice for most users at the time of writing. The combination of excellent overall performance, superior call quality, better noise cancellation, and more attractive pricing makes it the more practical option for daily use.

Choose the Samsung Galaxy Buds 3 Pro if you frequently take calls, want the best noise cancellation for travel or focus work, prefer universal comfort, or are already integrated into Samsung's device ecosystem. The price advantage makes these earbuds particularly compelling for users who want premium features without paying the absolute highest prices.

The Technics AZ100 commands its premium pricing through superior sound quality and advanced connectivity features. Choose Technics if you're an audio enthusiast who prioritizes sound quality above all else, need to manage three devices simultaneously, require extended battery life for long listening sessions, or want access to high-resolution audio codecs like LDAC.

For most users, the Samsung Galaxy Buds 3 Pro provides the better balance of performance, features, and value. However, serious music listeners who can appreciate the technical superiority of the Technics AZ100 will find the premium worthwhile for the enhanced audio experience. The key is honestly assessing whether you'll utilize the Technics' audiophile-focused features enough to justify the significantly higher investment.
