If you want lightweight wired on-ear listening with a folding design for exercise, choose Koss Sporta Pro On-Ear; if you need wireless freedom, sweat resistance, and long playback for exercise, choose PIIWIAU Neckband. The Koss puts a simple, bass-capable design first, while the PIIWIAU adds Bluetooth, call features, and a neckband built around active use.
• Koss Sporta Pro On-Ear: Its standout strength is a lightweight, collapsible on-ear design with a 3.5 mm cable and a stated 15 Hz to 25 kHz frequency range. Its trade-off is wired listening, with no stated sweat-resistance rating or noise-control feature.
• PIIWIAU Neckband: Its standout strength is wireless listening with up to 18 hours of music playback, an IPX5 rating, and a vibration alert for calls. Its trade-off is an in-ear fit attached to a neckband rather than the Koss’s foldable on-ear setup.
• Choose Koss if you prefer a simple wired pair, on-ear placement, and a portable folding design.
• Choose PIIWIAU if you want Bluetooth, exercise-focused sweat resistance, and call notifications while moving.
The Koss Sporta Pro On-Ear is a straightforward wired option for someone who values a lightweight design over wireless convenience. Its 3.5 mm jack connects through a cable, and its on-ear placement keeps the earcups outside the ear canal. The listed frequency range is 15 Hz to 25 kHz, and the product description calls out deep bass and a strong midrange. Those details make it worth considering if you are specifically looking for deep bass on ear headphones for exercise, while remembering that the actual fit and sound preference are personal.
Portability is one of its more distinctive advantages. The headphones collapse for storage, and a carrying pouch is included. The articulating headband can sit on the head or pivot to rest around the neck. That gives the design some flexibility between listening sessions, though it remains a wired pair rather than a Bluetooth option. If your workout setup already accommodates a cable and you want an uncomplicated pair that can fold away afterward, the Koss has a clear use case.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
I would skip it if wireless movement, an explicit sweat-resistance rating, or built-in call alerts are important to you. The listed noise-control field is “None,” so it is not the choice here for noise cancellation. Its on-ear fit also differs from the PIIWIAU’s in-ear earpieces. The Koss is a better fit for someone who wants simple wired listening and foldable portability, not for a buyer seeking a feature-rich workout headset.
The PIIWIAU Neckband is designed for listeners who want wireless earbuds connected by a neckband. Bluetooth 5.3 provides the wireless connection, with a stated range of up to 44 feet. Its retractable earpiece wires are intended to store neatly when not in use, and the flexible neckband weighs 1.7 ounces according to the product information. That design may appeal to someone who wants to keep the audio pieces close at hand between calls, commutes, or exercise sessions.
Battery and workout-related details are its strongest practical points. The listed battery supports up to 18 hours of music playback and up to 16 hours of talk time, and a full charge is stated to take 1.5 hours. The PIIWIAU also has an IPX5 sweatproof rating and a vibration alert for incoming calls. Those features make it the more exercise-oriented option on paper, especially if you want to move without a cable running to your device and still notice a call while exercising.
There are limits to what these features tell a shopper. The product information describes noise-canceling technology, a noise-canceling microphone, and active noise cancellation, but it does not specify a transparency mode. So if you are searching for transparency mode headphones for exercise, neither of these two options is clearly specified as providing that feature. The PIIWIAU is also an in-ear design, which may not suit someone who prefers on-ear headphones. Choose it for Bluetooth, sweat resistance, and longer stated playback; skip it if you specifically want the Koss’s wired on-ear fit or a documented transparency mode.
• Best for a wired 3.5 mm connection: Koss Sporta Pro On-Ear. It uses a cable and a 3.5 mm jack, while the PIIWIAU is a Bluetooth model.
• Best for stated music playback time: PIIWIAU Neckband. Its listed playback time is up to 18 hours, with up to 16 hours of talk time.
• Best for exercise where sweat resistance matters: PIIWIAU Neckband. Its IPX5 rating is a concrete advantage for workouts compared with the Koss, which has no stated sweat-resistance rating.
• Best for noticing incoming calls while moving: PIIWIAU Neckband. Its vibration alert is intended to notify the wearer of incoming calls.
• Best for someone who dislikes in-ear earpieces: Koss Sporta Pro On-Ear. It rests on the ears rather than using the PIIWIAU’s in-ear fit.
• Best for deep-bass interest in an on-ear format: Koss Sporta Pro On-Ear. Its description highlights deep bass and gives a 15 Hz to 25 kHz frequency range, although those specifications do not guarantee that every listener will prefer its sound.
• Best for Bluetooth range: PIIWIAU Neckband. The listed wireless range reaches up to 44 feet, whereas the Koss is wired.
The Koss lists media control, but that should not be mistaken for a specified touch-control system. If touch operation is a deciding requirement, neither product has enough confirmed information here to make that a safe reason to choose it.
The same care applies to noise features. The PIIWIAU is described as having noise cancellation, while the Koss lists no noise control. That gives the PIIWIAU the stronger claim for reducing background noise, but neither product is specified as having transparency mode. For exercise near traffic or other places where awareness matters, do not assume that either one offers a dedicated way to hear surroundings while listening.
My Verdict
In my opinion, I would choose the PIIWIAU Neckband for exercise because it combines Bluetooth, an IPX5 sweatproof rating, up to 18 hours of music playback, and a call vibration alert. Those features line up more directly with moving through workouts without a cable. I would choose the Koss Sporta Pro On-Ear instead if I wanted on-ear headphones, a 3.5 mm connection, and a design that folds for storage. The right call comes down to whether wireless workout features matter more than a simple wired, portable on-ear design.
