Monster over-ear headphones Persona 4th

Technical details

Noisy rides and long listening sessions can make it hard to focus—or to hear what’s around you when you need to. The Monster Persona 4th combines over-ear coverage with active noise cancellation for commutes and travel.

Three modes let you switch between Standard, Noise-canceling, and Transparency listening. The listing says hybrid ANC targets ambient noise, especially low and mid frequencies, and claims up to 90% noise reduction. That figure is a product claim, not a guarantee that every sound will disappear.

The headphones use 40mm drivers and offer a claimed 70 hours of playback. The listing also describes rapid charging: a 10-minute charge is said to provide five hours of listening. Memory-protein foam ear cups, an adjustable metal headband, rotating ear cups, and a foldable design round out the travel-focused setup. Bluetooth 6.0 supports wireless listening, and a Type-C cable provides a wired option.

Compatibility & requirements

For wireless use, you’ll need a device that supports Bluetooth. The product information doesn’t list a broader device compatibility chart, so check your device’s connection options if you’re unsure.

There’s an important detail for wired phone listening: the listing says the mobile connection supports Type-C input and output only. That makes the cable option useful when you want to keep listening without relying on the battery, but it may not fit a phone that lacks the required Type-C connection. The included information doesn’t specify whether other adapters are supported.

Usage tips

On a flight or a noisy train, Noise-canceling mode is the obvious place to start, particularly for steady low- and mid-frequency sounds. Use Transparency mode when you need more awareness of nearby conversation or announcements, then switch to Standard for everyday listening. These modes change the listening setup, the listing doesn’t describe them as a substitute for staying alert in busy surroundings.

For example, you could fold the headphones into a bag after a commute, then use them at home without changing devices or listening style. If the battery runs down, the Type-C wired connection offers another way to continue listening, subject to the phone connection requirement. The product description doesn’t provide details about microphone performance or call quality, so those should not be assumed.

Questions before you buy

Can you use them without Bluetooth? The listing describes a wired Type-C connection for continued listening when the battery runs out. For mobile phones, it specifies Type-C input and output.

What does Transparency mode do? It is intended to let more awareness of your surroundings through while you listen, which can be useful when traveling or working near other people.

Are they easy to pack? The ear cups rotate and the headphones fold, making them easier to store and carry than a fixed, non-folding design. The listing doesn’t give folded dimensions.

When it makes sense

A solid pick if you want over-ear headphones for travel, with multiple listening modes, a foldable build, and a long stated runtime. They offer more flexibility than basic wireless headphones without ANC, especially when switching between a noisy ride and a setting where you want to hear people nearby. Without having tried it, the clearest limitation is the wired phone requirement: Type-C input and output are specified, and no alternate mobile connection is listed. Not the best choice if you need confirmed call performance, detailed size information for packing, or a wired phone connection that doesn’t depend on Type-C.
