In a market saturated with wireless earbuds at every price point, Technics has positioned the EAH-AZ100 as a compelling mid-range option for those who want quality audio without breaking the bank. As the more affordable sibling to Technics’ premium EAH-AZ60 model, these earbuds offer impressive features while making strategic compromises to hit a more accessible price point. After spending several weeks with them, I’ve found they deliver surprising value for discerning listeners who don’t need every bell and whistle.

Sound Quality Assessment
The EAH-AZ100 earbuds showcase Technics’ audio engineering prowess through a balanced sound signature that prioritizes clarity over exaggerated frequencies. The 8mm dynamic drivers deliver excellent detail retrieval, particularly in the mid-range where vocals and acoustic instruments shine with natural warmth and presence.
The high frequencies offer good extension without becoming harsh or fatiguing during extended listening sessions. Cymbal crashes maintain their shimmer without becoming brittle, and string instruments retain their textural qualities. While audiophiles might detect a slight roll-off in the uppermost frequencies, most listeners will appreciate the forgiving yet detailed presentation.
Where these earbuds make their most noticeable compromise is in the bass department. The low-end is present and accurate, but lacks the authoritative punch and rumble found in Technics’ higher-end models. Electronic music fans and bass enthusiasts might find themselves wanting more thump, but those who prefer accurate reproduction over emphasized bass will appreciate the restraint shown here.
The soundstage is impressively wide for closed-back earbuds in this price range, with good instrument separation that allows complex arrangements to breathe. The acoustic chamber design helps create a more three-dimensional listening experience than many competitors can manage.
Without active noise cancellation, external sounds will inevitably bleed into your listening experience in noisy environments. However, the passive noise isolation provided by the silicone ear tips (which come in four sizes) is surprisingly effective at blocking ambient noise when fitted properly.
Comfort and Fit
Technics has created a genuinely comfortable pair of earbuds in the EAH-AZ100. At just 5.7g per earbud, they’re notably lighter than many competitors, reducing fatigue during long listening sessions. The ergonomic design contours nicely to the ear’s natural shape without applying pressure to sensitive areas.
The included silicone ear tips (XS, S, M, and L) provide enough variety to achieve a secure fit for most ear sizes. The medium tips created an excellent seal in my ears, staying firmly in place during moderate exercise without causing discomfort.
The lightweight design does come with a slight trade-off in perceived build quality. While the earbuds don’t feel fragile, they lack the substantial heft of premium models. However, the lighter weight ultimately benefits comfort, making these suitable for all-day wear.
Battery Life (Wireless)
Battery performance is one area where the EAH-AZ100 punches above its price class. The earbuds deliver approximately 7.5 hours of continuous use at moderate volume levels, outperforming many competitors in the same range. The charging case provides an additional 16.5 hours, bringing the total listening time to around 24 hours before needing a wall outlet.
A 15-minute quick charge provides about 70 minutes of playback time, which is convenient for those moments when you’ve forgotten to charge but need music for a commute or workout.
The absence of power-hungry ANC likely contributes to the impressive battery performance, making these an excellent choice for listeners who prioritize longevity over noise cancellation. The USB-C charging port is well-positioned and feels sturdy, though the lack of wireless charging capability is a noticeable omission in this price range.
Additional Features
While not as feature-rich as premium alternatives, the EAH-AZ100 offers practical functionality that enhances the user experience:
- Touch controls: The responsive touch surfaces allow for playback control, volume adjustment, and voice assistant activation. The controls are customizable via the Technics Audio Connect app, though options are somewhat limited.
- Ambient sound mode: A single tap enables ambient sound mode, which uses the microphones to feed external sounds into your listening experience—useful for brief conversations or situational awareness.
- Voice assistant integration: The earbuds work seamlessly with Siri, Google Assistant, and Alexa for hands-free operation.
- IPX4 water resistance: While not fully waterproof, the earbuds can withstand sweat and light rain, making them suitable for workouts and outdoor activities.
- Bluetooth 5.3: The latest Bluetooth standard ensures stable connectivity and improved power efficiency, with support for multipoint connection to two devices simultaneously (though switching between devices isn’t always seamless).
- Technics Audio Connect app: The companion app offers basic EQ customization, firmware updates, and control customization, though it lacks the depth of more premium competitors.
Notably absent is active noise cancellation, which might be a dealbreaker for commuters or office workers in noisy environments. However, this omission helps keep both the price and weight down while extending battery life.
Price/Value Analysis
At $129.99, the Technics EAH-AZ100 occupies a competitive mid-range price point where they face stiff competition from established brands. However, they distinguish themselves through superior sound quality and battery life compared to similarly priced alternatives.
The value proposition centers on audio performance and comfort rather than cutting-edge features. For listeners who prioritize sound quality over ANC or wireless charging, these earbuds represent excellent value. The build quality and two-year warranty also suggest these will outlast cheaper alternatives, potentially offering better long-term value despite the higher initial investment.
Comparison to Alternatives
Vs. Technics EAH-AZ60 ($229.99): The premium sibling offers ANC, better bass response, and wireless charging, but at a significantly higher price point. The AZ100 delivers about 80% of the sound quality at roughly 55% of the cost.
Vs. Sony WF-C710N ($119.99): The Technics offer notably better sound clarity, larger drivers, and longer battery life than Sony‘s budget option, justifying the modest price difference. Read more: Sony WF-C710N Wireless Earbuds: A Comprehensive Review
Vs. Jabra Elite 4 ($119.99): Jabra‘s offering includes ANC at a slightly lower price, but with inferior sound quality and less comfortable fit. The choice comes down to whether ANC or audio fidelity is your priority.
Vs. Nothing Ear (a) ($149.99): Nothing‘s earbuds offer more striking design and include ANC, but with shorter battery life and less refined sound. The Technics provide better audio performance for serious listeners.
Who Should Buy This
The Technics EAH-AZ100 are ideal for:
- Audio enthusiasts on a budget who prioritize sound quality over features
- Comfort-conscious listeners who wear earbuds for extended periods
- Active users needing reliable earbuds for workouts without requiring full waterproofing
- All-day users who value long battery life over noise cancellation
- Detail-oriented listeners who appreciate vocal clarity and natural instrument reproduction
They’re less suitable for:
- Frequent travelers or commuters in noisy environments who need ANC
- Bass enthusiasts seeking powerful low-end
- Those who prioritize wireless charging convenience
- Users needing extended water resistance for swimming or water sports
Takeaways
The Technics EAH-AZ100 successfully balances performance and price, offering exceptional sound clarity and comfort while making calculated compromises to reach a competitive price point. They represent Technics’ audio heritage well, focusing on sound reproduction rather than feature bloat.
What makes these earbuds compelling is their focus on fundamentals: comfortable fit, reliable connection, impressive battery life, and most importantly, refined sound quality that outperforms many competitors in the same price bracket. The mid-range excellence particularly stands out, making these ideal for vocal-centric music, podcasts, and audiobooks.
While not perfect—the lack of ANC and somewhat limited bass response are notable shortcomings—they deliver where it matters most for discerning listeners who don’t need every bell and whistle. For those willing to sacrifice some features for superior sound, the EAH-AZ100 represents one of the better values in the mid-range wireless earbud market in 2025.
In an increasingly crowded market where differentiation often comes through gimmicks rather than fundamental performance, Technics has created a product that stays true to the company’s audio-first philosophy while remaining accessible to a wider audience than their premium offerings.
