If you want wired, on-ear headphones with a bass-focused sound for study, choose Sony MDRXB450AP; if you need wireless earbuds with adaptive noise cancellation and a charging case, choose Anker Soundcore P40i. For a desk where a cable is welcome, I’d lean Sony; for moving between study spots or wanting fewer distractions from surrounding noise, I’d choose Anker.
• Sony MDRXB450AP: On-ear design, 30mm drivers, inline microphone and volume control; its main trade-off is a wired connection with no noise control.
• Anker Soundcore P40i: Wireless in-ear earbuds with adaptive ANC and a case that doubles as a phone stand; they require charging and have no headphone jack.
• Choose Sony if you prefer a cable, on-ear fit and straightforward controls for focused listening.
• Choose Anker if you want wireless freedom, adjustable noise cancellation and longer listening between charging stops.
• Neither is automatically the right study pick for everyone: the deciding factors are fit, noise control and how you want to connect.
The Sony MDRXB450AP is a wired, on-ear headset built around bass-forward listening. Its 30mm drivers cover a stated frequency range of 5–22 kHz, and the Acoustic Bass Booster is aimed at listeners who want low notes to stand out. That can suit music breaks between reading or writing sessions, especially if a wired connection fits your setup.
It has a 1.2-meter cord, an inline microphone and volume control, plus a swivel design intended to make it easier to carry. Sony also describes the cord as tangle-resistant. The headset is compatible with Apple and Android smartphones, and the SmartKey app can customize the inline remote function. Those features make it a practical option when you want wired listening and simple call controls in one device.

The trade-off is just as clear: there is no noise control, and the on-ear design is not the same as earbuds that sit inside the ear. If your study space is noisy and you want active noise cancellation, the Sony does not offer it. If you want a wireless setup or a fully enclosed listening experience, look elsewhere. For someone specifically searching for the best over ear headphones for study, note that this Sony is on-ear, not over-ear—a distinction worth checking before choosing it.
The Soundcore P40i takes the opposite approach: compact in-ear earbuds, Bluetooth 5.3 connectivity and adaptive active noise cancellation. The ANC adjusts to surrounding noise, which may be useful when your study environment changes from a quiet room to a shared space. It is a stronger feature match than the Sony for someone who wants help reducing distractions without a cable.
Battery life is a central part of the design. Anker states up to 12 hours on a single charge and up to 60 hours with the charging case. The case also works as a phone stand, giving it a second purpose for hands-free viewing during a break or video call. Six microphones and an AI algorithm are specified for calls, while 11mm composite drivers and BassUp technology point toward a bass-emphasized sound.
The compromises are that the P40i needs charging and connects wirelessly; it has no headphone jack. Its in-ear fit may also be less appealing if you prefer headphones resting on your ears. Although its adjustable ANC can help with changing background noise, the supplied information does not identify a transparency mode. So if you are looking for the best open ear earbuds for study or the best transparency mode headphone for study, do not assume the P40i provides those specific listening modes. Its stated strength is adaptive noise cancellation.
• Best for a wired study setup → Sony MDRXB450AP. Its 1.2-meter cord and 3.5 mm connection suit a desk or compatible phone where charging earbuds is one more task you would rather avoid.
• Best for adaptive noise cancellation → Anker Soundcore P40i. It has active noise cancellation that adjusts to surrounding noise; Sony lists no noise control.
• Best for on-ear fit → Sony MDRXB450AP. Choose it if you prefer a headphone that rests on the ears rather than an in-ear tip-style design.
• Best for wireless listening → Anker Soundcore P40i. Bluetooth 5.3 gives you a wireless connection, while the Sony is a wired headset.
• Best for long sessions away from a charger → Anker Soundcore P40i. Its stated battery life is up to 12 hours per charge, with up to 60 hours using the case.
• Best for inline controls and a microphone → Sony MDRXB450AP. Its cord includes a microphone and volume control, and the SmartKey app can customize the remote function.
• Best for calls and video chats as a stated feature → Anker Soundcore P40i. It has six microphones and an AI algorithm intended to support clear voice transmission.
• Best for a phone-stand case → Anker Soundcore P40i. Its charging case doubles as a stand for hands-free viewing; the Sony’s swivel design instead supports portability.
The biggest difference is not simply sound or convenience. It is the kind of study environment each one suits. Sony gives you a straightforward wired headset with bass emphasis and on-cord controls. Anker gives you wireless listening, adaptive ANC and a case with additional utility. If you regularly move between a quiet desk and noisier surroundings, those ANC and battery features may matter more than the Sony’s simpler connection. If you mostly study in one place and want a corded headset, the Sony’s approach may be enough.
My Verdict
For a quieter, wireless setup with active noise cancellation, the P40i has the more relevant features. The Sony is a sensible fit for wired listening at a desk, but it has no noise control.
The Sony is wired, so it does not rely on an earbud battery. The P40i provides up to 12 hours on one charge and up to 60 hours with its charging case, according to Anker.
I would not choose it on the assumption that it offers one.
Both models emphasize bass in their stated features. Sony has an Acoustic Bass Booster and 30mm drivers; Anker pairs 11mm composite drivers with BassUp technology. The data does not establish which will sound better to a particular listener.
