If you want a single, long-running Bluetooth headset for focused listening, choose Marshall Major IV On-Ear; if you need a 30-pack of simple wired headphones for shared use, choose Flutesan 30. For audiophiles choosing between these very different formats, the Marshall is the more practical personal-listening pick, while Flutesan is built around quantity, straightforward connections, and group settings.
That distinction matters more than the shared on-ear design. One is a rechargeable wireless headphone with a stated 80-plus hours of playtime and several listening controls; the other is a pack of 30 wired pairs with 3.5 mm plugs. Neither spec sheet gives enough detail to claim either delivers reference-grade sound, so the sensible choice is the one that suits how and where you listen.
Marshall Major IV On-Ear vs Flutesan 30 at a Glance
• Marshall Major IV: A Bluetooth headphone with 80-plus hours of stated wireless playtime, quick charging, wireless charging support, and a 3.5 mm jack; its trade-off is that it is one pair and needs charging for wireless use.
• Flutesan 30: A 30-pack of wired on-ear headphones with 3.5 mm plugs, suited to distributing across a group; its trade-off is a wired-only setup and fewer listening details in the available specifications.
• Marshall sound profile: Custom-tuned dynamic drivers are described as bass-forward, with smooth mids and bright treble; that is a stated tuning description, not proof that every listener will prefer it.
• Flutesan sound profile: The product is described as stereo with rich bass and clear high and midrange presentation, but no further tuning or wireless features are specified.
• Choose Marshall for personal listening, Bluetooth convenience, onboard playback and call controls, and long stretches between charges.
• Choose Flutesan when the main requirement is 30 wired pairs for children, classroom-style use, travel groups, or other shared settings.
The Marshall Major IV is the more feature-rich choice for one person who wants to listen without being tied to a cable. Its on-ear design pairs with Bluetooth, and the stated wireless playtime is over 80 hours. When the battery is low, the quick-charge claim is especially useful: 15 minutes of charging is specified to provide 15 hours of listening. That makes it a compelling option for commuters, frequent travelers, or anyone who dislikes making charging part of every day.
Its sound is described as custom-tuned, with strong bass, smooth mids, and brilliant treble. The listed frequency range is 20 Hz to 20 kHz, and the driver impedance is 32 ohms. Those figures help describe the hardware, but they do not tell us how the headphone will sound with every recording or source. For someone searching for the best headphone for audiophiles, I would focus less on the phrase “signature sound” and more on the practical promise: a defined tonal character, wireless use, and the option to plug in through the 3.5 mm socket.
The Major IV also has a multi-directional control knob for playback, track changes, volume, power, and calls. It folds into a more compact form, supports wireless charging, and includes a USB-C charging cable; a wireless charging pad is not included. The ear cushions are described as softer and shaped to fit the ear more closely. I would consider it if you want a reusable personal headset with useful controls and long battery life. Skip it if you need dozens of pairs for a group, or if you specifically want in-ear earbuds rather than an on-ear headband design.
Flutesan 30 is not a direct one-for-one personal-headphone rival. It is a 30-pack of wired on-ear headphones with 3.5 mm plugs, making its clearest use case distribution: a group that needs individual pairs for laptops, tablets, travel, or children’s activities. The described construction uses ABS plastic, rubber, and nylon, and the product information characterizes the headphones as impact resistant and intended for repeated use by children. That is a practical orientation, not a guarantee against damage.
The audio description calls out stereo playback, rich bass, and clear midrange and treble. The listed frequency range is 20 Hz to 20 kHz, and the driver type is dynamic. These details are broad: there is no stated Bluetooth connection, battery life, wireless charging, or playback control system comparable to the Marshall’s knob. The wired 3.5 mm connection keeps the design simple, but it also means the listening device needs a compatible jack or another suitable connection arrangement.

• Best for supplying a group → Flutesan 30. It is a 30-pack, with each pair described as individually packaged.
• Best for quick top-ups between listening sessions → Marshall Major IV. Its stated quick-charge feature gives 15 hours of listening from 15 minutes of charging.

The word “audiophile” can mean different things. Some shoppers want a carefully described sound signature; others want a dependable listening routine without frequent charging. The available details give the Marshall a more developed personal-use feature set, but do not establish that it is objectively more accurate or universally better sounding. Flutesan’s case is about putting many wired pairs into use, not offering the same individual listening experience.
I would choose the Marshall Major IV for personal listening, especially if I wanted a headband headphones for audiophiles option with Bluetooth, long stated battery life, and useful controls. Its 3.5 mm socket also gives it a wired fallback and a way to share listening.
For audiophiles comparing these two, my recommendation is Marshall: it offers more clearly specified listening features for one person, while Flutesan 30 makes sense when the priority is a pack of wired headphones for a group. Neither specification set alone proves sound quality beyond those described characteristics.
I would choose the Marshall for individual listening because it specifies Bluetooth, a sound profile, playback controls, and long battery life. Neither product’s listed specifications establish sound accuracy or guarantee that its tuning will suit every listener.

For a school, activity group, or household that needs many basic pairs at once, the pack format is the central advantage. The package is described as containing 30 individually packaged headphones, and the product information lists multiple colors. If you are comparing the best in ear earbuds for audiophiles, Flutesan is not that category: these are on-ear wired headphones, not in-ear earbuds. I would skip them if you want one Bluetooth headset for private daily listening, long battery intervals, or the controls and charging options described for the Major IV.
