What Soundcore Space A40 owners think
Most owners who stick with the Space A40 point to the fit and the battery as the reasons why, calling them comfortable enough to sleep in and able to run for days between charges, with ANC and overall value rounding out the appeal at this price. A meaningful minority pushes back hard on the sound, describing bass that is thin or absent, especially before certain firmware updates, and ranking the tuning behind other Soundcore models like the Liberty 3 Pro and 4NC. A smaller group also reports batteries fading within a year or two, sometimes down to one working bud, plus scattered complaints about fit and inconsistent ANC. The split lands along expectations: buyers focused on comfort and battery come away satisfied, while anyone chasing bass or long-term reliability tends to leave disappointed.
What Bose QuietComfort Ultra Earbuds (2nd Gen) owners say
“I will be returning my AP3 and just sticking with the Bose gen 2.”
“They are great for the price one of the ones I miss most (I lose a lot of buds) and have a soft spot for. Extremely ergonomic fit, and the NC isn’t bad either.”
“It’s probably the most comfortable in-ears I’ve ever worn before, and I liked that they kinda went against the grain by having a more neutral sound out-of-the-box”
“These were definitely not the best choice in earbuds. Sound and ANC are pretty bang average for the price. The only good thing about them really is the battery life, even the fit is poor on me.”
