Tayogo T6 poolside transmitter with coach mic and W23 bone-conduction receivers

Artistic swimming underwater audio is a different problem than “play a playlist while I freestyle.” Synchro / artistic sets need the whole squad on the same routine track and live coach counts without stopping the music. A deck boombox (or a phone propped on the gutter) only solves the dry half of that job.

What actually breaks with speakers on deck

Once heads go under for figures, hybrids, or a full routine run, water eats the music. Athletes surface on different bars. The coach starts shouting counts across the glass. Someone pauses Spotify so the cue can land — and the next run never matches the one before.

Personal “waterproof Bluetooth” buds do not fix the team problem either. Bluetooth is a short dry-air link. Underwater, that link drops. Even if one swimmer hears a private track, twelve headsets with twelve file versions is chaos for a duet or team.

The workflow that stuck in our pool tests

We stopped trying to make the boombox louder and looked for music + coach cues underwater on one shared feed:

  1. Phone (or tablet) holds the official routine file.
  2. A dry poolside T6 mixes that phone audio with a coach mic.
  3. W23 bone-conduction receivers on the athletes pick up the combined channel by FM — not underwater Bluetooth.

That distinction matters. Phone Bluetooth only reaches the dry transmitter. The hop to the squad is FM receive. Clubs comparing “Bluetooth underwater” myths to a dedicated artistic kit should keep those two links separate.

How it works: phone and coach mic into T6, FM to W23 underwater

Soft checklist before you trust any kit

  • Keep the transmitter dry, upright, antenna fully extended, not buried behind a metal rack.
  • Match channels before the whistle.
  • Test at the depths you actually use — shallow-end demos can lie.
  • Bone conduction stays open-ear; waterproof earplugs often clean up the feed under a noisy pool.
  • One-way coach → athlete is enough for most artistic blocks; you do not need athletes talking back mid-figure.

We used the Tayogo T6 + W23 Artistic Swimming Audio System as the reference kit for these notes — peer pool testing, not a paid review. Product page: https://tayogo.com/products/tayogo-t6-w23-artistic-swimming-audio-system-music-coach-voice-mixer

If your club is still on boombox + shouting, start with a solo or duet kit and validate reception in your pool before scaling receivers. Your deck layout will matter more than the sticker on the box.

Masters practice taught me this the hard way: a coach can yell from the deck and I still miss the set change once my head is under.

Sound does travel in water, but the path from a dry deck to a submerged ear is messy. Air → water at the surface reflects a lot of energy. Pool noise (splash, gutters, other lanes) masks the rest. By the time a cue reaches you mid-pull, it is often just a muffled blob — not “ten more” vs “easy 50.”

What people actually do (peer notes, not a product pitch):

  1. Surface checkpoints — coach talks on walls / between repeats; you pause and look up. Works, but breaks rhythm on longer sets.
  2. Visual signals — hand counts, whiteboard, lane lights. Great for “how many,” weak for tone or timing tips mid-rep.
  3. Dedicated coach-to-swimmer audio — a dry mic on deck feeding waterproof receivers the athlete wears. That is a different lane from music headphones: the job is voice clarity and range, not a playlist.

A few habits that help any coach-voice workflow: – Agree on short callouts before the set (same words every time). – Keep the deck mic / box elevated and away from wet splash zones. – If you share a channel with another squad, confirm you are not talking over them.

I still love silent yards. But when the set is technical, missing the cue costs more than the extra gear fuss. Just a lane note from someone who has shrugged at the wrong wall more than once.

Pool notes: why waterproof Bluetooth dies mid-lap

Lap swimming with “waterproof Bluetooth” usually disappoints once your head is under — water between phone and ears kills the link. That physics hasn’t changed.

What actually works in practice falls into three lanes (no product pitch): 1) Onboard MP3 on the headset — fixed playlist, no deck box. 2) Live stream — phone stays dry on a poolside transmitter; underwater hop is usually FM to waterproof receivers. 3) Coach voice mid-set — that’s a communicator workflow, not a music headset.

Transmitter tips that help any setup: antenna fully extended, box elevated in an open deck spot, matching channel. Just a recreational lane note — not a product review.
