If you want to stream music from your phone straight into the pool — Spotify, Amazon Music, YouTube, podcasts, whatever your app of choice is — choose Tayogo Swimming Headphones; if you need a self-contained pair that carries its own music with zero phone or transmitter involved, choose MARLALL Soft Liquid Silicone.
• Tayogo Swimming Headphones biggest strength: a two-piece system (T6 transmitter + W25 bone conduction headphones) that streams live audio from your phone while you swim, with a 150-meter working range and 16 channels to keep the signal private.
• Tayogo Swimming Headphones biggest trade-off: it's a system, not a single device — you're managing a transmitter, two cables, a case, and a mode switch between Bluetooth and Receiving.
• MARLALL Soft Liquid Silicone biggest strength: total simplicity — built-in storage, magnetic charging, and IPX8 waterproofing in one lightweight unit with no phone, no transmitter, no app.
• MARLALL Soft Liquid Silicone biggest trade-off: swimming only works in MP3 mode, so you must preload tracks yourself; Bluetooth doesn't function underwater, and music from a phone app can't be copied directly to the headphone's memory.
• Choose Tayogo if you want live streaming and coach communication. Choose MARLALL if you want untethered, load-it-and-go swimming.
This is the setup for swimmers who don't want to think about playlists the night before. The T6 transmitter stays poolside, paired to your phone over Bluetooth 5.4 with a 33-foot Bluetooth range for normal use, and it rebroadcasts to the W25 headphones up to 150 meters away — and 2 meters under water. That means you can push off the wall, swim a full lap, and still get a clean signal. Sixteen available channels exist specifically so your feed doesn't collide with someone else's.
The W25 itself is a bone conduction, open-ear design with an 8-ohm impedance, 96 dB sensitivity, and a 20 Hz–20,000 Hz frequency range. Bone conduction means your ear canals stay open, so you keep pool awareness and avoid the plugged-up feeling of in-ear buds. Battery is split across two devices: the transmitter runs up to 8 hours, and the headphones run up to 15 hours in Bluetooth mode or 8 hours in Receiving mode, with a 2-hour charge time.
There's a second audience here that's easy to overlook: swim coaches. The PPT button sends real-time instructions from coach to student, which turns this from a music device into a training tool. If you're running lessons, that button alone justifies the system.
Buy it if you want live streaming from your phone, you swim in a pool where you can leave a transmitter on the deck, or you coach. Skip it if you swim in open water far from your phone, or you want one object and nothing else.
MARLALL takes the opposite approach: everything lives inside the headphone. There's built-in storage (32G per the product name) and a magnetic charging cable that doubles as a data connection — plug it into a computer and the internal memory shows up so you can drag playlists across. Charge for 1.5 hours and you get up to 7 hours of continuous playback. No phone on the deck. No transmitter. No pairing ritual before you get in.
The build is the headline feature. The overmold liquid silicone is skin-friendly and ultra-soft, and the ear-hook shape distributes pressure instead of clamping down on one spot. At 22.68 grams it's genuinely light, which matters when you're wearing something through a long set. IPX8/IP68 waterproofing covers swimming, snorkeling, and surfing, and the open-ear bone conduction design keeps your ears unobstructed for safety — traffic on a run, other swimmers in a lane.
The catch is honest and clearly labeled: Bluetooth does not work underwater. Swimming requires MP3 mode, and music from a phone app can't be copied straight to the memory — you manage files from a computer. Also dry the microphone after swimming to avoid call issues.
Buy it if you want one lightweight device, you're fine preparing playlists in advance, or you swim where leaving a phone poolside isn't practical. Skip it if you want live streaming or need to take calls mid-session.

My Verdict
In my opinion, the deciding question is whether you want your phone in the loop. If you do — if you live in Spotify and want it playing mid-lap — I'd buy the Tayogo Swimming Headphones. The 150-meter range, 16 channels, and the coach PPT button make it the more capable system, and the dual Bluetooth/Receiving modes mean it works as an everyday headset too.
how to make headphones music louder
Check the source first — your phone or app volume, then any in-app volume limiter. On the Tayogo W25, the 96 dB sensitivity and 8-ohm impedance mean it doesn't need much power to reach a strong level, so the bottleneck is usually the transmitting device. Bone conduction models like both of these send sound through your cheekbone, so ambient pool noise will always compete with them.
how to fix stereo headphones
Start with the simple causes: charge the unit fully, confirm the correct mode is selected, and re-pair over Bluetooth if you're using it. On the Tayogo system, remember that underwater listening runs in Receiving mode from the T6 transmitter, not Bluetooth — if you're in the wrong mode, you'll get silence. On the MARLALL, Bluetooth isn't supported underwater at all, so switch to MP3 mode. If one side is still dead, it's a hardware issue, not a settings one.
how to test stereo headphones
Play a track with clearly separated left and right channels and listen for both sides independently. For bone conduction, place the transducers properly against your cheekbones — a loose fit makes one side sound weak even when it's working fine. On the MARLALL, test in MP3 mode since that's the mode you'll actually swim in, and test the Tayogo in Receiving mode for the same reason.
how to make stereo headphones
If you mean loading your own music onto them: the MARLALL Soft Liquid Silicone is the one built for this. Connect the magnetic charging cable to a computer, access the internal storage, and drag your files across. Note that music from a phone app can't be copied directly to the memory card — you'll need to manage files from a desktop. The Tayogo W25 doesn't work this way at all; it streams from your phone through the T6 transmitter instead.
