Poly Voyager Free 20 vs Soundcore Liberty 4 NC Comparison

Poly Voyager Free 20

Each bud has three noise-cancelling microphones, which Poly aims at your mouth to separate your voice from typing and background chatter. Poly processing suppresses typing and background chatter well. Without a dongle, laptop calls use standard Bluetooth, which narrows the audio when the mic is active. The Voyager Free 60+ includes a USB adapter for steadier PC calls and certification.

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.

Poly Voyager Free 20

Adaptive ANC adjusts its strength to the surroundings, and a transparency mode lets you hear colleagues without removing a bud. Poly keeps the controls simple, with a long press switching between the two modes. Cancellation is good in offices and on commutes, reducing air conditioning hum and distant chatter. It is not as strong as premium consumer buds such as the AirPods Pro 3, but enough to help with focus work.

Soundcore Liberty 4 NC

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.

Poly Voyager Free 20

Poly quotes up to 8 hours with ANC on and 12 hours off, with 28 and 42 hours total with the case. That is enough for a full workday of calls and music without a top-up. Few business earbuds last as long. The case charges by USB-C or on a Qi wireless pad, so a desk charger keeps it topped up without cables.

Soundcore Liberty 4 NC

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.

The buds are light and shaped for long wear, with several tip sizes and an IP56 rating for dust and water. Many users can wear them through a full workday without discomfort. The shape stays stable when you talk, which matters on long calls. The case is compact and charges wirelessly on a Qi pad, which suits desk setups that already have a wireless charger.

Soundcore Liberty 4 NC

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.

Poly Voyager Free 20

Bluetooth 5.4 supports multipoint, keeping the buds connected to a phone and a laptop at the same time so you do not need to re-pair between devices. Switching between devices is automatic when a call arrives. Poly Lens app on mobile and desktop handles settings and updates. They are not certified for Teams or Zoom, and no USB dongle is included.

Soundcore Liberty 4 NC

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.

Poly Voyager Free 20

Each bud has a 10 mm speaker, and Poly tunes them for clear voice reproduction. Codec support covers SBC and AAC. For background music while working they are pleasant, but music lovers will prefer consumer-focused buds with richer tuning. The Poly Lens app offers EQ presets that add a little warmth for listening between meetings.

Soundcore Liberty 4 NC

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.
