Soundcore Liberty 4 NC vs Technics EAH-AZ100 Comparison

Soundcore Liberty 4 NC

Six microphones with AI processing handle calls. Voice pickup is clear in quiet rooms and acceptable in offices. In wind or on busy streets, background noise and voice artefacts become noticeable. For short calls it is fine, but daily meeting users should choose a business earbud. Laptop calls use standard Bluetooth headset audio, which narrows the sound compared with music playback.

Technics EAH-AZ100

Voice Focus AI uses multiple microphones and processing to isolate your voice from background noise. Technics trained the algorithm to recognise voice versus ambient sound. For hybrid workers, this makes them a credible alternative to business-focused earbuds, especially when paired with three-device multipoint and a laptop that stays connected all day.

Adaptive ANC 2.0 measures the ear canal and surroundings to adjust cancellation. Transparency mode is also included. For under 100 dollars, ANC is impressive, cutting engines, fans and traffic well. It cannot match the Bose QC Ultra Earbuds on voices, but the gap is smaller than the price suggests. Getting a good seal with the right tip size matters most.

Technics EAH-AZ100

Adaptive hybrid ANC uses feedforward and feedback microphones to adjust to your surroundings and fit. An ambient mode is available for conversations and announcements. Noise cancelling is strong across low and mid frequencies, removing engine hum and office chatter effectively. It is not quite as aggressive as the best from Sony and Bose, but it remains well above average.

Soundcore quotes up to 10 hours per charge, or 8 hours with ANC on, and up to 50 hours with the case. With LDAC, that falls to about 6 hours. That is excellent for the price and outlasts many premium earbuds. A full week of commuting is possible before charging the case.

Technics EAH-AZ100

Technics rates up to 10 hours with ANC on using AAC, and 28 hours with the case. LDAC reduces that to 7 hours per charge and 18 hours total. Ten hours with noise cancelling on is excellent and covers a full workday of calls and music. The case supports Qi wireless charging and USB-C.

The stem-style buds are light and rated IPX4 for sweat and splashes. Soundcore includes five tip sizes. The stems make them easy to remove and adjust, though the shape is less distinctive than pricier rivals. The case is compact with a sliding lid, which is easy to open with one hand.

Technics EAH-AZ100

Technics lists roughly 5.9 g per earpiece and redesigned the shell to be smaller and more ergonomic than the AZ80, with multiple tip sizes included in the box to suit different ear canals. They sit securely for long sessions and seal well, which helps both bass response and noise cancelling.

Bluetooth 5.3 supports multipoint, so the buds stay connected to a phone and a laptop at the same time. Multipoint is rare at this price and useful for hybrid workers who take calls on both devices. The Soundcore app handles EQ, ANC modes and firmware. Note that LDAC and multipoint cannot be used together on some firmware versions.

Technics EAH-AZ100

Bluetooth 5.3 supports SBC, AAC, LDAC and LC3. Multipoint connects up to three devices at once, which is rare among earbuds. Three devices means a laptop, a phone and a tablet can stay connected together, and the buds switch to whichever one starts playing. That is a big advantage for people who move between work and personal devices.

Each bud uses an 11 mm custom driver, and the buds support LDAC Hi-Res Wireless Audio on compatible Android phones, plus SBC and AAC. Default tuning is bass heavy, which some will enjoy on a commute. The app's EQ presets and HearID personalisation calm the low end and bring vocals forward. iPhone users get AAC rather than LDAC; Apple's AirPods Pro 3 are the iPhone-native alternative.

Technics EAH-AZ100

Each bud uses a 10 mm Magnetic Fluid Driver, a design Technics brought over from its high-end headphones. The fluid around the voice coil reduces distortion and allows more precise control of the diaphragm. LDAC support lets Android users stream higher-resolution audio, and Dolby Atmos adds spatial playback. They compete directly with the AirPods Pro 3 at the premium end.
