- Which has better noise cancellation?
- Both use real-time adaptive ANC. The Liberty 4 Pro claims 7 sensors and 3x stronger noise reduction, while the Liberty 5 claims 2x stronger voice reduction. Neither figure is directly comparable, so try both if ANC is your top priority.
- Which lasts longer on a charge?
- The Liberty 4 Pro: 10 hours, or 40 with the case. The Liberty 5 gives 8 hours with ANC on. The Liberty 5 charges faster, though: 10 minutes for 5 hours versus 5 minutes for 4 hours.
- Is the Liberty 4 Pro worth the extra $15?
- Only if battery life and the larger driver matter to you. The Liberty 5 adds LDAC, Dolby Audio, and IP55 for less money at current prices.
- Which is better for running and the gym?
- The Liberty 5 has a stated IP55 dust and water rating, which is the clearer spec for sweat and dust. The Liberty 4 Pro is listed for sports and is water-resistant, but its dust rating is not given.
- Which is better for calls?
- The Liberty 5 lists 6-mic AI clear calls and 2x stronger voice reduction. The Liberty 4 Pro lists 7 sensors but no call-specific claim, so the Liberty 5 has the clearer case on paper.
- Do both support high-quality Bluetooth audio?
- The Liberty 5 supports LDAC and Dolby Audio. The Liberty 4 Pro's listing does not name LDAC, so the Liberty 5 is the safer pick for hi-res streaming.
