If you want wired, noise-reducing earbuds for the gym, choose Plugfones Basic; if you need a Bluetooth transmitter to use your own wireless headphones with gym equipment, choose SUNITEC Airplane. Plugfones combines listening with passive ear protection, while SUNITEC converts a 3.5 mm audio connection into wireless audio. They solve different problems, so the key question is whether you need the earbuds or the connection adapter.
Plugfones Basic vs SUNITEC Airplane at a Glance
• Plugfones Basic: Its foam in-ear design provides a stated 25 dB NRR and wired listening; the trade-off is that it needs a 3.5 mm headphone jack and has a cord.
• For gym sessions with nearby noise: Plugfones Basic is the more direct fit if you want earplugs and earbuds in one product.
• For gym machines with a 3.5 mm audio output: SUNITEC is the better fit if you already own wireless headphones and want to connect them without a headphone cable.
• Choose Plugfones Basic for a self-contained wired listening setup with passive noise reduction.
• Choose SUNITEC Airplane for Bluetooth transmission, compatible Auracast sharing, and use across other 3.5 mm audio sources.
Plugfones Basic is a wired, in-ear headphone that combines an audio speaker with a soft foam earplug. Its stated Noise Reduction Rating is 25 dB, and the product information describes passive noise cancellation. For a gym session, that combination makes sense if you want to listen to audio while reducing some surrounding sound. The 3.5 mm connection is straightforward, provided the device you want to use has a compatible headphone jack.
The trade-off is equally clear: this is not a wireless setup. The cord connects to the audio source, and the Basic does not work as a Bluetooth receiver for headphones you already own. If you want to move around without a wired connection, or your phone and gym equipment lack a 3.5 mm jack, this is not the more convenient option.
I would consider Plugfones Basic for someone who wants earplugs and headphones together, especially when reducing environmental noise is part of the goal. It may also suit someone comparing the best comfortable bone conduction headphones for gym options, but it is important to recognize that these are not bone conduction headphones. They sit in the ear, use soft foam, and have a cord. If you specifically want an open-ear or wireless design, look elsewhere.

Its appeal at the gym depends on the equipment and headphones you bring. If a cardio machine has a 3.5 mm output and you want to listen through your own wireless headphones, SUNITEC provides a way to bridge that connection. It supports classic Bluetooth codecs including SBC, aptX, aptX Adaptive, and aptX HD, as well as LC3 for Auracast. The listed Bluetooth operation range is up to 33 feet, while the Auracast broadcast range is up to 65 feet.
There are practical limits. SUNITEC does not provide earphones, and it does not reduce noise by sealing your ears. You need compatible receiving headphones or hearing aids, and the source needs a 3.5 mm output. The transmitter offers up to 35 hours of playtime per charge and recharges by USB-C, but it adds another device to keep charged. If you want a ready-to-wear wired earplug headphone, Plugfones is the simpler product.
• Best for passive noise reduction built into the listening device → Plugfones Basic. It combines foam earplugs with audio and has a stated 25 dB NRR.
• Best for turning a 3.5 mm source into Bluetooth audio → SUNITEC Airplane. It sends sound to compatible wireless headphones or hearing aids.
• Best for a simple wired gym setup → Plugfones Basic. There is no transmitter battery to charge, though the audio source must have a 3.5 mm jack.
• Best for wireless headphones at a gym machine → SUNITEC Airplane. Choose it if the machine has a 3.5 mm output and your headphones support its Bluetooth connection.
• Best for sharing audio through Auracast → SUNITEC Airplane. It supports broadcasting to Auracast-enabled headphones or speakers.
• Best for someone who does not already own headphones → Plugfones Basic. The earbuds are part of the product; SUNITEC is only the transmitter.
• Best for an airplane entertainment system → SUNITEC Airplane. Its included dual-prong adapter is designed for airplane jacks.
• Best for reducing setup pieces → Plugfones Basic. SUNITEC can add wireless flexibility, but it requires a source, the transmitter, and a compatible listening device.
The phrase hi res wireless headset for gym can point shoppers toward a wireless listening setup, but neither product is itself a wireless headset. SUNITEC supports aptX HD and aptX Adaptive when paired with compatible headphones; Plugfones Basic is a wired earbud. Similarly, shoppers searching for the best on ear headphones for gym should note that both products are different from an on-ear headphone: Plugfones sits in the ear, while SUNITEC is an adapter that works with headphones you provide.
A central difference is what each product does to the sound path. Plugfones is the listening device. Its foam earplug design is intended to reduce environmental noise while audio plays. SUNITEC sits between the source and the listening device. It handles wireless transmission, but any noise reduction or fit comes from the headphones you pair with it.
That distinction matters in a busy gym. If you want one wired product with stated noise reduction, Plugfones has the more direct setup. If you already have wireless headphones you prefer and want to use them with equipment that outputs sound through 3.5 mm, SUNITEC is the more flexible connection tool. Neither is a universal replacement for the other.
For the gym, I would choose Plugfones Basic if my priority were a single wired device that combines listening with passive noise reduction.
I would choose SUNITEC Airplane instead if I already owned compatible wireless headphones and needed a 3.5 mm-to-Bluetooth transmitter.
My overall pick for someone seeking gym earbuds rather than an adapter is Plugfones Basic, because its purpose is clear and it includes the earphones.
If wireless connection is the deciding factor, SUNITEC is the more suitable tool.
They fit different gym setups. Plugfones Basic is a wired earbud with foam earplugs and a stated 25 dB NRR; SUNITEC sends audio from a 3.5 mm output to compatible wireless headphones.
No headphones are listed as included. SUNITEC is a Bluetooth transmitter, so you need compatible headphones, AirPods, or hearing aids to receive its audio.
Plugfones Basic has a 3.5 mm wired connection. A phone without a compatible headphone jack would need a suitable connection solution; Bluetooth pairing is not how this product connects.
Plugfones Basic has a stated 25 dB NRR and a foam in-ear design. SUNITEC is a transmitter, so its noise reduction depends on the headphones used with it; the transmitter itself is not described as hearing protection.
