If you want a versatile everyday neckband for workouts, calls and all-day listening on dry land, choose Toztnix Neckband; if you need headphones that genuinely survive being submerged while you swim laps, choose esonstyle Swimming Headphones Underwater.
• Toztnix Neckband — biggest strength: up to 35 hours of playback with fast USB-C charging and a light 1 oz neckband that stays put through workouts.
• Toztnix Neckband — biggest trade-off: IPX5 means splash- and sweat-resistant, not submersible, so it is not a swimming product.
• esonstyle Swimming Headphones Underwater — biggest strength: a true IP68 rated, fully submersible design with 8 GB of built-in MP3 storage so you can leave your phone on the pool deck.
• esonstyle Swimming Headphones Underwater — biggest trade-off: underwater you must switch to MP3 mode, because Bluetooth simply will not carry through water, and battery life is a shorter 8 hours.
• Who each pick is for: Toztnix for gym, running, commuting and calls; esonstyle for swimmers, surfers and anyone who trains where water is part of the session.
The Toztnix Neckband is a classic around-the-neck Bluetooth headset, and it is built around two ideas: long battery life and staying put. The 10 mm bio-diaphragm dynamic drivers are tuned for deep bass, and the neckband itself weighs about 1 oz, made from memory skin-friendly silicone and composite fibre so it can be flexed repeatedly without losing shape. The earbuds are magnetic, so they snap together and hang around your neck instead of tangling in a pocket. Three ear tip sizes and an ergonomic in-ear shape are meant to keep them seated during movement.
Battery is the headline number here: up to 35 hours of playback and 1200 hours of standby on a 1.5-hour charge, plus a quick-charge top-up that gives roughly 3 hours of listening from 10 minutes on the cable. Bluetooth 6.0 handles the connection with a claimed 16 ms latency, which matters if you watch video, and the set can pair with multiple devices. Physical buttons handle play, pause, track skipping and calls, and ENC noise cancellation with the built-in mic is designed to lift your voice and suppress a large share of surrounding noise on calls.
Buy the Toztnix if you want one headset for the gym, runs, walks, commutes and phone calls, and you value not recharging every couple of days. Skip it if your main activity happens in a pool or the sea — IPX5 covers sweat and splashes, not immersion. Also skip it if you want a completely open ear; this is an in-ear design, so your ears are plugged.
The esonstyle set is a different animal. It is a bone conduction headphone, which means it sits on your cheekbones and sends sound through them, leaving your ear canals completely open. That open-ear approach is the reason it makes sense for running and cycling outdoors — you hear traffic and your surroundings while your music plays. The frame is a 28 g titanium build with a flexible fit, and the housing is ABS plastic. There is no headphone jack at all; everything is wireless or internal storage.
The defining feature is the IP68 rating. This is a fully submersible design rated to withstand depths up to 3 metres for over an hour, which covers swimming, surfing, kayaking and heavy rain. The catch is important and the brand states it plainly: underwater you must switch from Bluetooth to MP3 mode, because water interferes with Bluetooth transmission. That is why the 8 GB of built-in memory exists — it holds thousands of songs, so you can swim laps with no phone anywhere near the water. A double-click on the MFB button flips between Bluetooth and MP3, and triple-clicking switches MP3 playback to shuffle. Battery life is 8 hours, and the set supports Bluetooth 6.0 for calls and streaming when you are dry.
Buy the esonstyle if you swim, surf, kayak or train in the rain and you want audio that does not care about water. Skip it if you mostly take calls and watch video on land and want maximum battery — 8 hours is a normal training-week figure, not an all-week one. And skip it if you dislike the physical feel of bone conduction or want the isolation of an in-ear seal.
Side-by-Side: Which Should You Choose?
• Best for swimming and full submersion → esonstyle Swimming Headphones Underwater. IP68 versus IPX5 is the whole decision in one line.
• Best for phone calls → Toztnix Neckband. A built-in mic with ENC voice pickup is a core part of the design; the esonstyle handles calls too, but its focus is sport audio.
• Best for leaving your phone behind → esonstyle Swimming Headphones Underwater. 8 GB of onboard storage means no phone, no streaming, no signal problem.
• Best for gym, running and commuting → Toztnix Neckband. Sweat-resistant, magnetic, 1 oz, and it reconnects automatically to your last paired device.
• Best for outdoor safety awareness → esonstyle Swimming Headphones Underwater. Bone conduction keeps your ears open, so you hear cars and other people.
• Best for low-latency video and multi-device switching → Toztnix Neckband. Bluetooth 6.0 with a 16 ms latency figure and multi-device pairing.
• Best for in-ear bass and passive isolation → Toztnix Neckband. Sealed ear tips and 10 mm dynamic drivers give you the thump that open-ear designs deliberately avoid.
In my opinion, these two barely compete — they solve different problems. If your training happens in water, I would buy the esonstyle Swimming Headphones Underwater, because nothing else in this pair is actually rated to go under. If water is only ever sweat and rain, I would buy the Toztnix Neckband: the 35-hour battery, the light magnetic neckband and the call-focused mic make it the better daily driver by a wide margin. Pick based on where you sweat, not on which one sounds more impressive on paper.
FAQ
Yes, on land. Bluetooth 6.0 handles pairing, streaming and calls when you are dry. Underwater, Bluetooth will not hold a signal, so you must switch to MP3 mode — a double-click on the MFB button does it.
The Toztnix Neckband is rated up to 35 hours of playback and charges in about 1.5 hours, with a quick charge that gives hours of listening from a short top-up. The esonstyle is rated 8 hours, which suits a training week but means more frequent charging.
