Soundcore Liberty 5 Pro Max — The Earbuds That Record Your Meetings

The World Record Call Quality — What It Actually Means

The G-MOS score isn't a marketing figure. It's a composite standard used by telecom standards bodies to measure speech quality — combining voice clarity and background noise suppression into a single objective number. Soundcore hit a G-MOS of 3.76, verified against 14 rival earbuds from other flagship brands. That's a real benchmark, not a company-run test, and it's the same methodology carriers use to evaluate phone call quality.

How does it achieve this? The Thus AI chip combines data from 10 sensors — eight microphones plus two bone conduction sensors that detect skull vibrations from your voice. The bone conduction piece is what makes this different. Most earbuds only have external mics. The bone conduction sensors give the chip a second clean signal that confirms what your voice actually sounds like, independent of ambient noise. In 100dB+ environments — a busy street, a construction site, an open-plan office — callers report your voice comes through cleanly. I've tested this on a windy commute and in a coffee shop and both times got a reaction from the other person along the lines of "where are you? It sounds like you're inside."

The earbuds sit flush — no awkward stem sticking out.

The AI Note-Taker — The Real Reason to Buy the Pro Max

The standard Liberty 5 Pro doesn't have the note-taker — that's the $60 Pro Max premium. The case has a built-in microphone that records room audio during in-person meetings. When the meeting is done, you double-tap a button on the back of the case, it syncs to the Soundcore app, and within a few minutes you have a full transcript with speaker identification, key points extracted, and action items listed. It supports 154 languages.

This is a real workflow shift for meetings and lectures. You're already carrying the case. You don't need a separate device, you don't need to prop your phone on the table, and you don't need to remember to open an app before the meeting starts. It just records. The AI summary quality is genuinely good — it pulls out the things you'd actually want to remember rather than giving you a wall of transcript text to scroll through.

The free Starter Plan gives you 120 minutes of AI transcription per month for 24 months, which covers occasional meeting use comfortably. If you're in meetings all day, the Pro tier at $99.99/year is probably what you need. And worth being upfront about: the note-taker currently only captures in-room audio. It does not capture Zoom calls or Teams meetings yet — Soundcore says that's coming around September 2026 via firmware update. For in-person meetings, it works exactly as promised.

The AMOLED Case — Genuinely Useful, Not a Gimmick

I fully expected the 1.78" touchscreen case to be a gimmick. It isn't. Being able to adjust ANC level, switch between sound modes, start a recording, or check battery status without touching your phone is legitimately convenient during commutes and in meetings. The screen is bright, responsive, and reads clearly in daylight.

Sound Quality, ANC, and Battery

Out of the box, these have a V-shaped sound signature — bass and treble boosted, mids slightly back. Bass lovers will love this immediately. Anyone who finds boosted bass fatiguing will want to run the HearID 5.0 personalisation first, which generates a custom EQ profile tuned to your actual hearing. After HearID, the sound shifts to something much more balanced and the mid-range opens up properly. Worth doing before you form a final opinion on the sound.

The Adaptive ANC 4.0 processes 384,000 noise signals per second and adapts in real time to your environment — it's a meaningful step up from the previous gen, particularly on low-frequency rumble like tube trains and aircraft engines. Comfort is excellent at 5.6g per earbud with six ear tip sizes included. I wore these for a three-hour meeting without discomfort. Battery life: 6.5 hours buds with ANC on, 28 hours total with the case, and 5 minutes of charging gives you 4 hours of playtime. That last number is the one that actually matters day to day.

Who Should Buy This?

The Liberty 5 Pro Max makes most sense for people who attend in-person meetings, lectures, or interviews and want a single device that handles both ears and notes. Against AirPods Pro (2nd gen) and Sony WF-1000XM5, it offers measurably better call quality, a more customisable app experience, significantly more battery life, and the note-taker case that neither competitor can match. At $229.99 these are premium earbuds — and they earn it. Trust me on this one.
