If you want a wired, adjustable on-ear headphone with an in-line volume control for a call center, choose Koss KTXPro1; if you need USB-C headphones in a 20-pack for shared desks or school-style workspaces, choose WASCLEWAY USB-C Headphones Bulk. Koss is the more focused individual headset option, while WASCLEWAY is built around quantity and USB-C connectivity. Neither is a Bluetooth headset.
Koss KTXPro1 vs WASCLEWAY USB-C Headphones Bulk at a Glance
• WASCLEWAY USB-C Headphones Bulk’s biggest strength: a 20-pack with USB-C connections and adjustable headbands; trade-off: its 4.5-foot cable and lack of noise control may limit placement and call privacy.
• Koss suits an individual who wants a straightforward wired headset and needs to adjust listening volume at the cable.
• WASCLEWAY suits a workplace or institution equipping multiple people with USB-C devices.
• For either pick, confirm that the connection type matches the device you plan to use.
Koss KTXPro1 is an on-ear wired headphone with a standard 3.5 mm plug. Its titanium-coated dynamic drivers are rated at 60 ohms and cover a stated frequency range of 15–25,000 Hz. That range describes the headphone’s audio specification; it does not, by itself, guarantee how clearly a caller’s voice will come through in a particular room or on a particular computer.
The practical appeal is its simple setup. Connect it to a device with a compatible 3.5 mm jack, then use the in-line controller to adjust volume without reaching for the computer or tablet. The adjustable headband, soft flexible head sling, and plush foam cushions are designed to make the on-ear fit more accommodating for extended listening. Those are useful details for a desk worker who wears headphones through long stretches of calls or audio tasks.
There is an important limitation for call-center shoppers: the listed features do not include a microphone, noise cancellation, or wireless connectivity. The KTXPro1 can serve as a wired listening option, but buyers who need a complete calling headset should verify that their setup supplies a separate microphone. Its 3.5 mm plug also needs to match the device; it is not the direct USB-C choice here.

Who should skip it: Skip Koss if you need USB-C connectivity, a built-in microphone, Bluetooth, or a single purchase to equip many desks.
WASCLEWAY is designed as a 20-pack of wired, on-ear headphones with USB-C connectors. Each cable is listed as 4.5 feet long, and the product information describes an adjustable headband made from flexible plastic. Those features make the set easier to consider for shared environments where several people need headphones that connect to USB-C devices, including compatible computers, Chromebooks, tablets, and smartphones.
The trade-offs matter. The headphones are wired, and the listed features do not specify a microphone or noise control. The product information gives an impedance of 140 ohms, but provides no comparable frequency range or sensitivity figure. So shoppers should not treat the available numbers as proof that WASCLEWAY will sound clearer or louder than Koss. Its multi-color design and bulk format fit shared use better than a buyer seeking one individually specified audio-focused model.
Who should skip it: Skip WASCLEWAY if you need a Bluetooth headset, confirmed microphone features, or a longer cable than 4.5 feet.
• Best for a 3.5 mm audio jack → Koss KTXPro1. Its listed connection is a standard 3.5 mm plug, so it fits devices that offer that jack.
• Best for USB-C devices → WASCLEWAY. Its wired connection is USB-C, making it the direct match for compatible USB-C computers, tablets, and smartphones.
• Best for equipping multiple people → WASCLEWAY. The 20-pack is the clearest reason to choose it for a shared workspace rather than buying an individual set.
• Best for cable-side volume adjustment → Koss KTXPro1. The in-line controller lets the listener change volume from the cable.
• Best for a stated audio frequency range → Koss KTXPro1. Its listed range is 15–25,000 Hz, alongside 60-ohm titanium-coated dynamic drivers.
• Best for an adjustable fit across users → WASCLEWAY. Its headband is adjustable and described as flexible, which is relevant when headphones are shared.
• Best when cable reach is a priority → Check your desk before choosing. WASCLEWAY specifies a 4.5-foot cable; the Koss data does not provide a cable length, so there is no factual length comparison.
• Best when you need a complete calling setup → Neither is confirmed by the listed features. Neither product’s supplied specifications identify a microphone. Confirm how calls will be captured before relying on either as a call-center headset.
Buying Considerations
Start with the device connection, not the product name. Koss uses a 3.5 mm plug, while WASCLEWAY uses USB-C. A computer may have one, the other, or both; check the actual equipment at the workstation. A mismatch can mean the headphones will not connect as intended, regardless of their other features.
Then consider who will use the equipment. Koss is the simpler choice for an individual who values an in-line volume control and has a compatible 3.5 mm device. WASCLEWAY is more naturally suited to shared deployment: its package contains 20 headphones, its USB-C plug targets compatible devices, and its adjustable headband is intended to accommodate different users. Its 4.5-foot cable is a concrete constraint to compare with the distance between each person and their computer.
Finally, be careful with the numbers. Koss provides a frequency range and driver details; WASCLEWAY lists impedance. These are different specifications and do not establish a direct sound-quality winner on their own. Choose based on the connection, controls, pack size, and fit details that match your workplace, and check the current price on Amazon if cost is part of your decision.
I would choose Koss KTXPro1 for one person who has a 3.5 mm connection and wants an in-line volume control with an adjustable on-ear fit. For a call center, though, I would first confirm that each workstation has a separate microphone, since neither product’s listed features identify one. If I were outfitting multiple USB-C desks instead, I would choose WASCLEWAY for its 20-pack and direct USB-C connection. My personal pick is Koss for individual wired listening, not as a complete calling headset.
FAQ
No. Both are described as wired. Koss uses a 3.5 mm plug; WASCLEWAY uses USB-C. Neither should be treated as a Bluetooth headset for call center use.
If callers need staff to speak through the headphones or the room needs noise reduction, verify those requirements separately.
Koss is listed with a 3.5 mm connection, not USB-C. WASCLEWAY is the direct USB-C option, provided the computer supports USB-C audio. Check the device’s ports and compatibility before selecting either.
