Poly Voyager Free 60+ vs Soundcore Liberty 4 NC Comparison

Poly Voyager Free 60+

Each bud has three microphones that steer toward your mouth, with WindSmart processing for outdoor calls. Poly also lets you set sidetone to low, medium or high, so you can hear your own voice naturally. For call-heavy days, a boom headset such as the Poly Voyager Focus 2 places a mic closer to the mouth.

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.

Hybrid adaptive ANC uses inner and outer microphones and adjusts for how well the buds fit. A transparency mode lets surrounding sound through when you need it. On a plane or bus the cancellation is respectable for business buds, cutting steady engine noise well. It is weaker against voices and sudden sounds, where Apple and Bose are ahead.

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 60+

Poly lists up to 5.5 hours of talk time per charge, or 16.5 hours with the case. With ANC on, music runs up to 8 hours, or 24 hours in total. A 15-minute charge gives about 1 hour 12 minutes of talk time, and standby lasts up to 30 days including the case.

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.

Poly Voyager Free 60+

Each bud weighs 5.8 g and measures about 16 x 26 x 38 mm, with a short stem. Poly includes S, M and L ear tips and a pressure-relief design. IP54 covers splashes and dust. That is enough for rain on the commute but less than the IP57 that Jabra and Apple offer.

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.

The buds use Bluetooth 5.3 with multipoint to two devices and remember up to eight. The BT700 adapter extends range to about 30 m and supports Microsoft Swift Pair on Windows. The touchscreen case shows battery, mute state and volume, and lets you switch between the two active devices. Plug the included cable into a seatback socket, and the case streams that audio to the buds at up to about 3 m.

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 60+

Each bud has a 10 mm speaker, larger than most business earbuds use. Poly applies a dynamic EQ that switches between wideband voice, up to 7 kHz on PC calls, and a full 20 Hz to 20 kHz media mode. In media mode they have more bass punch than the Jabra Evolve2 Buds, and music sounds fuller.

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.
