Anker Soundcore Liberty 4 NC vs Soundcore AeroFit 2
Quick take: The Soundcore AeroFit 2 costs $5 less; the Anker Soundcore Liberty 4 NC has active noise cancelling while the Soundcore AeroFit 2 doesn't; the Soundcore AeroFit 2 lasts longer per charge (10 hrs).
Which one to buy
On paper, these two Soundcore models are nearly identical: about $70, LDAC, multipoint, wireless charging, a 10-minute charge that adds four hours, and a good app EQ. They're opposites in practice. The Liberty 4 NC seals your ear and cancels noise, and owners compare its ANC to Bose's at a third of the price. The AeroFit 2 is an open-ear hook that hangs speakers outside the ear canal, so you hear traffic, coworkers and your own footsteps on purpose. There's no ANC and no isolation. The question is whether you want to block the world out or keep hearing it.
Each one's comfort problem follows from its design. The Liberty's bulky shell makes a meaningful share of ears ache within one or two hours, and its flat stems can seal loosely, which hurts both bass and ANC. The AeroFit 2 puts no pressure inside the ear and runs 10 hours per charge against the Liberty's 8, but its hooks can feel bulky and can get in the way of glasses arms. For sound, the Liberty's bass shows up once fit and HearID are sorted out. The AeroFit's bass stays light and depends on aiming its rotating driver, and critical listeners hear a grainy midrange.
For workouts, the AeroFit 2 stays put while running and has IP55 against the Liberty's IPX4. Even so, some heavy sweaters have gone through several pairs. The Liberty can't run LDAC and multipoint at the same time, and owners call its mic poor. The AeroFit's mic is just okay and struggles in wind.
Anker Soundcore Liberty 4 NC
If you want quiet on planes, buses and in open offices, and your ears handle a chunky bud.
Soundcore AeroFit 2
If you run outdoors, need to hear your surroundings, or can't stand anything inside your ear canal. You give up ANC and bass depth for that.

Anker Soundcore Liberty 4 NC vs Soundcore AeroFit 2: common questions
Can the AeroFit 2 replace ANC earbuds on a flight?▾
No. It's open-ear with no isolation, so cabin noise reaches you fully and you'd have to raise the volume to compete with it. The Liberty 4 NC is the one built for planes, and owners say its ANC handles engine drone well when the fit is right.
Is the AeroFit 2 safer than the Liberty 4 NC for running near traffic?▾
The AeroFit 2, because it leaves your ears open, and owners say it stays planted during runs. You can use the Liberty's transparency mode, but a sealed bud with ANC is designed to cut out exactly the sounds a runner needs to hear.
My ears hurt with most earbuds. Should I try the AeroFit 2 or the Liberty 4 NC?▾
The AeroFit 2 sits outside the ear, so nothing presses inside it. The Liberty 4 NC's comfort complaints are the most common thing owners mention, with soreness after one or two hours for many. Glasses wearers should check how the AeroFit's hooks sit with their frames.
