If you want lightweight wired clip-on headphones for library listening, choose Koss KSC75; if you need wireless over-ear headphones for library study sessions, choose Belkin SoundForm Surround. Koss keeps things simple and portable, while Belkin adds Bluetooth, a microphone, and up to 60 hours of battery life. For a library, the key choice is whether you prefer the Koss ear-clip design or Belkin’s larger over-ear fit.
Koss KSC75 vs Belkin SoundForm Surround at a Glance
• Koss KSC75: Its lightweight ear-clip design and 3.5 mm wired connection make it easy to carry; the trade-off is that it has no wireless connection or noise control.
• Koss KSC75 is for listeners who want a compact, straightforward wired option and don’t need Bluetooth.
• Belkin SoundForm Surround is for listeners who want wireless convenience, a built-in call microphone, and the option to connect two devices at once.
The Koss KSC75 makes the most sense if you want headphones that keep your setup simple. Its ear clips rest around the ears rather than using a conventional headband, and the soft hooks rotate. The headphones are described as ultra-lightweight and portable, so they’re an appealing format for someone carrying a small listening setup between home, campus, and the library.
The wired 3.5 mm connection avoids the need to charge the headphones or pair them with a device. Koss lists a 15 Hz–25,000 Hz frequency range, dynamic titanium-coated drivers, and neodymium iron boron magnets. Those specifications describe the audio hardware, but they don’t establish how it will sound to every listener or in every room.
Choose the KSC75 if a light, wired, clip-on design is what you want. Skip it if you need Bluetooth, a built-in microphone for calls, or noise control: the listed noise-control feature is none, and the product is not described as wireless. Its open, on-ear clip format also isn’t the same kind of enclosed over-ear fit offered by Belkin.

Belkin SoundForm Surround is the more feature-rich option for someone who wants wireless over-ear headphones. Bluetooth 5.4 connects to compatible devices within a listed range of 33 feet, and multipoint lets the headphones stay connected to two devices at once. That could suit a student moving between a laptop and phone without wanting to reconnect every time.
Belkin lists up to 60 hours of battery life, along with a built-in microphone featuring environmental noise cancellation for calls. The over-ear cups are described as soft, and the adjustable headband and foldable design add flexibility for longer listening and carrying the headphones. The product also supports a 3.5 mm connection, and its package information lists an AUX cable and a USB-C charging and audio cable.
Choose the Belkin if wireless listening, calls, and switching between devices matter more than minimizing bulk. Its 40 mm drivers and listed 20 Hz–20 kHz frequency range describe its audio hardware, but they don’t tell the whole story of sound quality. Skip it if you don’t want to charge headphones or prefer the very light, ear-clip form of the Koss.
• Best for a simple wired setup → Koss KSC75. It uses a 3.5 mm jack and doesn’t require a wireless connection.
• Best for Bluetooth listening → Belkin SoundForm Surround. It uses Bluetooth 5.4 and lists a 33-foot connection range.
• Best for switching between a laptop and phone → Belkin SoundForm Surround. Its multipoint feature supports two connected devices.
• Best for a light, clip-on design → Koss KSC75. Its ear hooks rotate, and the design is described as ultra-lightweight.
• Best for long stretches without frequent charging → Belkin SoundForm Surround. Belkin lists up to 60 hours of battery life.
• Best for calls while wearing headphones → Belkin SoundForm Surround. It has a built-in microphone with environmental noise cancellation.
• Best if you don’t want to manage a battery → Koss KSC75. The wired design doesn’t rely on a rechargeable battery.
• Best if you want over-ear cups and a foldable design → Belkin SoundForm Surround. The Koss instead uses ear clips and an on-ear placement.
For library use, neither set of listed features establishes how much sound people nearby will hear or how much room noise the headphones will block. Belkin describes its ear cups as offering immersive sound absorption, but that is not the same as a stated noise-cancellation specification for listening. Its listed active noise cancellation shouldn’t be confused with the environmental noise cancellation specified for the microphone. Koss lists no noise control.
That distinction matters in a quiet shared space. If you’re choosing the best clip on earbuds for library listening, the KSC75 is the closer match by design, though it is described as headphones rather than earbuds. If you mean the best headphones for library study, decide first whether the ear-clip fit or over-ear fit better matches your preferences. For someone searching for the best rechargeable wireless headset for library use, Belkin is the clear fit in this pair because it combines Bluetooth with a long listed battery life.
The connection details may also shape your decision. Koss is straightforward when the device you plan to use has a 3.5 mm jack. Belkin gives you Bluetooth as its main wireless option, plus the listed AUX cable and a USB-C charging and audio cable. That added flexibility is useful if your routine includes several devices, but it also means more features to consider than with the Koss.
In my opinion, I’d choose the Belkin SoundForm Surround for a library routine built around wireless listening, laptop-and-phone switching, and extended sessions between charges. Its 60-hour listed battery life and two-device multipoint connection make it the more adaptable option for that use.
I’d choose the KSC75 instead if carrying a lightweight wired clip-on set matters more than wireless features. For a library, Belkin is my pick when wireless convenience is the priority; Koss is my pick when simple wired portability comes first.
