If you want wireless noise control and long battery life for studying, choose Anker Soundcore P31i; if you need wired, sound-isolating earbuds for focused listening, choose JotVira Ear Monitor Headphones.
The P31i is the more flexible everyday pick, with adaptive noise cancelling, Bluetooth, and up to 50 hours of listening with its case. JotVira keeps things simpler: a wired in-ear monitor design, a detachable cable, and a USB-C-to-3.5 mm adapter.
For studying, I’d choose the P31i when freedom from a cable and adjustable noise reduction matter most. JotVira makes more sense when a direct wired connection and passive sound isolation better fit your setup.
• Anker Soundcore P31i strength: Adaptive ANC, Bluetooth 6.1, and up to 50 hours of total playtime with the case. Trade-off: It needs charging and is not a wired option.
• JotVira Ear Monitor Headphones strength: Wired listening with a detachable two-pin cable, a 3.5 mm connection, and a USB-C adapter. Trade-off: No wireless listening or adaptive ANC.
• The P31i adds six microphones for calls and supports fast charging; JotVira’s stated focus is sound isolation and monitoring rather than call features.
• Choose Anker for wireless study sessions, calls, and flexible noise control. Choose JotVira for a wired listening setup, monitoring, or a device connection that suits its included adapters.
The P31i is an in-ear Bluetooth earbud set built around convenience and noise control. Its adaptive ANC detects the surrounding environment and adjusts its noise-cancelling level; the product specifies noise reduction of up to 52 dB. That makes it the more feature-rich choice for someone who studies in places where the background changes, such as a shared room or a busy commute. ANC is not a promise of silence, but it gives the P31i a tool that JotVira does not offer.

The P31i also suits people who take calls or listen to more than music. It has six microphones with AI noise reduction, wind-noise reduction, Hi-Res audio with LDAC, spatial audio, and real-time AI translation in over 100 languages. Those extras make it a versatile set of earbuds, but they may not matter to someone who simply wants a wired connection for a laptop or music setup. If you do not want another device to charge, the P31i is the less natural fit.
JotVira is the straightforward choice for someone who wants wired in-ear monitors rather than Bluetooth earbuds. It uses a detachable two-pin cable and a 3.5 mm jack, and the package includes a USB-C-to-3.5 mm adapter. That gives it a practical path to compatible devices with a 3.5 mm input and, using the included adapter, USB-C ports. The exact device compatibility still depends on the device and its connection support.
The product information describes sound isolation, a 10 mm dynamic driver, and a frequency range of 20 Hz to 20 kHz. Its wired design can suit focused listening, music monitoring, or a study desk where you would rather connect directly than keep track of battery life. The cable is detachable, which is useful if you prefer a replaceable cable arrangement. A protective flannelette bag and replacement ear tips are also listed as included.
The trade-off is that JotVira does not offer wireless convenience, adaptive ANC, or a stated battery system. Its noise control is described as sound isolation, not active noise cancellation. That may be enough for someone who wants an in-ear fit to help limit ambient sound, but it is a different approach from the P31i’s adjustable electronic noise control. If your study routine involves moving around freely or taking calls with dedicated microphone features, the information provided gives JotVira fewer reasons to choose it.
• Best for wireless studying → Anker Soundcore P31i. Bluetooth 6.1 means no listening cable to manage, and adaptive ANC gives you a way to respond to changing background noise.
• Best for long sessions away from a charger → Anker Soundcore P31i. Its stated battery life reaches up to 50 hours with the case, or up to 40 hours total with ANC enabled.
• Best for a wired setup → JotVira Ear Monitor Headphones. Its 3.5 mm jack and included USB-C adapter suit listeners who prefer a cable over Bluetooth.
• Best for someone who wants sound isolation without ANC → JotVira Ear Monitor Headphones. It is described as sound-isolating, while the P31i’s main noise-control feature is adaptive ANC.
• Best for calls and outdoor voice pickup → Anker Soundcore P31i. Six microphones and wind-noise reduction are specified for clearer calls.
• Best for monitoring or a detachable-cable arrangement → JotVira Ear Monitor Headphones. Its IEM format and detachable two-pin cable are the more relevant features for that use.
• Best for translation and extra listening features → Anker Soundcore P31i. It includes real-time AI translation, LDAC audio, and spatial audio.
• Best for a simple, no-battery listening routine → JotVira Ear Monitor Headphones. Its wired design avoids charging the earbuds, though it does require a compatible connection and a cable.
In my opinion, I’d buy the Anker Soundcore P31i for studying because adaptive ANC, wireless convenience, and its stated battery life fit a broader range of study settings.
It is also the more capable option if I want call features or translation alongside listening.
I’d choose JotVira instead for a wired desk setup, monitoring, or a preference for a detachable cable and sound isolation.
For most people searching for the best wireless headphones for studying, the P31i is the clearer fit; neither is specifically described as sleep headphones or kids headphones.
The P31i is the stronger fit if you want wireless listening and adaptive ANC. JotVira suits a wired study setup where sound isolation and a detachable cable matter more.
The listed noise-control type is sound isolation. The product information does not specify active noise cancelling, so it should not be treated as equivalent to the P31i’s adaptive ANC.
The P31i is specified for up to 10 hours per charge and up to 50 hours with its case, with lower figures when ANC is on. JotVira is wired, so no battery-life figure is provided.
Value depends on the current price and on which features you will use. Check the current price on Amazon, then compare it with your priorities: wireless ANC and call features on the P31i, or wired listening and a detachable cable on JotVira.
