If you want wireless, sweat-resistant listening for a nurse’s commute or workout, choose Otium Earbuds; if you need a wired connection from a compatible iPhone to an AUX input, choose Seulliya Aux Cord. These serve different jobs: one is a Bluetooth neckband-style earbud set, while the other is a short Lightning-to-3.5 mm audio cable. For nurses, the deciding question is whether you need freedom from a cable or a direct wired link to an audio device.
• Otium Earbuds: Bluetooth 5.3, ear hooks, IPX7 water resistance, and up to 16 hours of playback; the trade-off is that they need charging and use in-ear earpieces.
• Seulliya Aux Cord: A 3.3-foot Lightning-to-3.5 mm cable with an MFi-certified chip; the trade-off is that it tethers your phone to the audio input and only fits compatible connections.
• Choose Otium for wireless listening, workouts, and calls without holding your phone.
• Choose Seulliya to connect a compatible iPhone to a car stereo, speaker, or headphones with a 3.5 mm input.
Otium Earbuds are the practical choice when you want to move around without a cable running from your phone to your ears. They connect over Bluetooth 5.3, with a stated range of up to 30 feet. The in-ear shape and silicone ear hooks are designed to help keep them in place, while the IPX7 rating is intended to protect against sweat, splashes, and rain. That combination makes them a more natural fit for a walk, a gym session, or a commute than a wired AUX cord.
The claimed playback time is up to 16 hours, and the listed charging time is one hour. The earbuds also have button controls for music and phone use, a built-in microphone, and sound isolation technology. Those features may suit a nurse who wants to take a call or listen during personal time without handling a phone constantly. They are not noise-cancelling headphones, though: the product information describes sound isolation and noise suppression, not active noise cancellation. They also require a Bluetooth-enabled device and regular charging.

If your priority is a wired connection to a car or stereo, Otium is not the right tool. These earbuds do not replace an AUX cable, and their in-ear fit may not suit someone who dislikes earpieces or ear hooks. For shoppers searching for the best sweat resistant true wireless earbuds for nurses, there is an important distinction: Otium uses a neckband design, so the earbuds are wireless to the phone but joined by a band and cable between them. That can be a useful compromise if you want a secure workout fit rather than two fully separate buds.
Seulliya Aux Cord is a straightforward way to send audio from a compatible Lightning-equipped iPhone to a device with a 3.5 mm AUX input. The cable is 3.3 feet long and includes a built-in digital-to-analog converter. It is designed for plug-and-play use without an external power source or driver. That makes it a sensible option for connecting to a car stereo, speaker, or wired headphones when the phone and audio device have the matching ports.
The cable’s MFi certification and stated iOS compatibility are useful details for people who want a Lightning connection rather than a wireless pairing process. Its nylon-braided construction is described as having a bend lifespan of more than 15,000 bends. That suggests a design intended to handle repeated packing and everyday handling, but it remains a physical cable: it can snag, limit movement, and only reaches as far as its length allows.
This is not a headphone set, so it cannot play audio on its own or provide a microphone, ear hooks, or sweat protection. It also is not a USB-C cable; its phone-side connector is Lightning. A nurse who wants personal listening while walking around should look at the Otium earbuds instead. Seulliya makes more sense for a stationary setup, a car ride, or a phone-to-stereo connection where keeping a wired path is the point.
Side-by-Side: Which Should You Choose?
• Best for listening while moving around → Otium Earbuds. Bluetooth connection and ear hooks avoid a cable from your phone to your ears.
• Best for connecting a compatible iPhone to a car AUX system → Seulliya Aux Cord. It converts the Lightning connection to a 3.5 mm audio connection.
• Best for avoiding battery management → Seulliya Aux Cord. It is a plug-in cable and does not need its own battery or charging.
• Best for taking calls without reaching for the phone → Otium Earbuds. They include a built-in microphone and button controls.
• Best for a wired audio path → Seulliya Aux Cord. Its DAC and copper wiring are intended to transmit audio through a direct connection.
• Best for workouts or runs → Otium Earbuds. The ear hooks, neckband design, and water-resistance rating are more suited to active use than a loose cable.
• Best for a speaker or wired headphones with a 3.5 mm input → Seulliya Aux Cord. It is built for that connection, provided the phone has a compatible Lightning port.
The search phrase “best rechargeable headband headphones for nurses” points toward a different kind of product than either item exactly describes. Otium is rechargeable and has a neckband, but it is an in-ear earbud set rather than headband headphones. Seulliya is not a headset at all. Likewise, neither item should be mistaken for a dedicated pair of over-ear noise-cancelling headphones: Otium offers sound isolation and noise suppression, while Seulliya is simply an audio cable.
I would choose Otium Earbuds for a nurse who wants wireless listening, a secure fit for exercise, and an advertised playback time of up to 16 hours. The ear hooks, microphone, and IPX7 rating give it more versatility for personal listening than a short AUX cable.
I’d choose Seulliya only when the specific need is connecting a compatible iPhone to a 3.5 mm input. For nurses choosing between these two for everyday wireless listening, my recommendation is Otium.
They are described as using sound isolation and noise suppression technology. The product details do not specify active noise cancellation, so I would not treat them as a substitute for dedicated noise-cancelling headphones.
It is designed for compatible iPhones with a Lightning connector, including the listed iPhone generations. It connects to a 3.5 mm AUX input on the other end, so the audio device also needs that matching input.
Otium is the more practical option for moving around because it connects by Bluetooth and has ear hooks. Seulliya’s 3.3-foot cable physically connects the phone to the audio device, which is better for a fixed or seated setup.
Otium earbuds have a rechargeable battery; the stated playback time is up to 16 hours, with a listed charging time of one hour. Seulliya is a passive wired cable and does not need charging.
