If you want over-ear comfort, wired listening, and up to 55 hours of playback for gym sessions, choose QCY H3; if you need compact earbuds with adaptive noise cancellation and a charging case, choose Anker Soundcore P31i. For gym use, I’d pick based on whether you prefer a full-size headset or a small in-ear fit: these are very different designs, not two versions of the same idea.
• QCY H3’s biggest strength: Over-ear design, up to 55 hours of playback, and a 3.5 mm audio connection. Trade-off: Bulky compared with earbuds, and its listed quick charge gives less listening time than the P31i’s.
• Anker Soundcore P31i’s biggest strength: In-ear portability, adaptive ANC, and a case-based setup with up to 50 hours of total playback. Trade-off: No headphone jack, and its single-charge listening time is shorter than the QCY’s total stated battery life.
• Choose QCY H3 if you want headphones you can wear over your ears, use with a cable, and adjust through an app.
• Choose Anker Soundcore P31i if you want earbuds with a charging case, six microphones, and built-in translation features.
The QCY H3 is an over-ear wireless headphone with 40 mm dynamic drivers, Bluetooth 5.4, and adaptive active noise cancellation. Its listed playback time reaches up to 55 hours, and a 10-minute quick charge is specified to provide five hours of playback. Those figures make it the stronger fit if you want long listening sessions without relying on a charging case.
There is also a practical flexibility advantage: the H3 supports both wireless and wired listening, with a 3.5 mm jack and an audio cable included. It offers app-based custom EQ, LDAC support, and a game mode with latency listed as low as 60 milliseconds. The headphones also advertise spatial sound. If you switch between music, videos, gaming, and calls, that broad feature mix may matter more than compactness.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
For the gym, the key question is whether you like exercising in over-ear headphones. The H3’s form gives you ear coverage and avoids having to manage separate earbuds and a case, but it is physically less compact than an in-ear pair. I’d skip it if your priority is a small pocketable setup or if you specifically want earbuds. And although the H3 includes spatial sound and gaming-oriented low latency, that does not make it a dedicated gaming headset; its everyday appeal is the mix of over-ear listening, long stated battery life, and wired fallback.
The Anker Soundcore P31i is an in-ear wireless earbud set with adaptive ANC, Bluetooth 6.1, and an included charging case. Its stated total playback reaches up to 50 hours with the case, while a single charge is listed for up to 10 hours. With ANC on, the listed figures are eight hours per charge and 40 hours total. A 10-minute charge is said to provide 3.5 hours of listening.
That case-based setup is the central difference. You can carry the earbuds in a compact format, then recharge them from the case between uses. The P31i also includes six microphones with an AI noise-reduction feature for calls, plus translation functionality described as covering more than 100 languages. It supports LDAC and spatial audio, and the included ear tips come in four sizes: XS, S, M, and L.
For gym use, the P31i makes more sense if you prefer an in-ear fit and want to keep your headphones small when you are not wearing them. Its stated adaptive noise cancellation and microphone features add flexibility beyond music listening. But it has no headphone jack, so there is no wired fallback. If over-ear headphones are your preference, or you want the longer stated battery figure without counting on a case, the QCY H3 is the clearer fit.
Side-by-Side: Which Should You Choose?
• Choose QCY H3 for the longer stated playback figure: It lists up to 55 hours, compared with up to 50 hours for the P31i when its charging case is included.
• Choose P31i for an in-ear design: Its earbuds and charging case are the more compact style of the two; the QCY H3 is an over-ear headphone.
• Choose P31i if you want call-focused microphone features: It has six microphones and an AI noise-reduction feature. The QCY H3’s listed feature set does not specify a microphone count or comparable call-processing system.
• Choose P31i for the stated ANC-on battery figures: It lists up to eight hours per charge and 40 hours total with ANC on. The QCY H3’s supplied battery information gives a 55-hour figure but does not specify an ANC-on total.
• Choose QCY H3 for app-based EQ: Its features include custom EQ through an app. The P31i’s listed information does not specify a comparable EQ feature.
• Choose either if spatial audio is a priority: Both list spatial audio. The available specifications do not establish that one will sound better to you, so fit and listening style are more useful deciding factors.
• Neither is automatically the best multipoint gaming headset for gym use: The supplied feature details do not specify multipoint pairing for either model. The QCY H3 does list game mode and 60-millisecond latency, but that alone does not establish multipoint support.
I’d choose the QCY H3 for gym listening if I wanted an over-ear fit, a wired option, and the longer stated playback time.
I’d choose the P31i instead if compact earbuds, a charging case, and its call and translation features mattered more.
My personal pick for the gym is the QCY H3, because its 3.5 mm connection and up-to-55-hour playback give it more flexibility across listening situations.
That recommendation is about the listed features, not a claim that over-ear headphones suit every workout.
It comes down to fit preference. The QCY H3 is over-ear and supports wired listening; the P31i is in-ear and comes with a charging case. Choose the style you are more comfortable wearing during exercise.
The QCY H3 lists up to 55 hours of playback. The P31i lists up to 50 hours with its case, including up to 40 hours total with ANC on. These figures describe different listening conditions, so they are not a direct like-for-like comparison.
The QCY H3 does list Bluetooth 5.4 and a game mode with latency as low as 60 milliseconds, but that does not confirm multipoint pairing.
Both products list spatial audio, so the available details do not give a factual basis to declare one the better spatial-audio option. The QCY H3 is over-ear; the P31i is in-ear. Consider which form you prefer, and check the current price on Amazon if you are comparing overall value.
