Start with the watches and earbuds you already own. If you need recommendations, this is the short list we'd start with for a dependable CoachCall setup.
A Note on High School Compliance
What matters for high school baseball
As of 2024, many states allow electronic pitch calling in high school baseball, one way to catcher only, but as of 2026, a growing number of state associations have approved pilot electronic pitch calling and coach-to-player communication for high school baseball with additional players involved. Rules still vary, so check with your state athletic association or league to be sure what's allowed.
NFHS 1-6-2 Situation 5 says a catcher wearing a one-way electronic communication device with an earpiece and no microphone is legal. NFHS Situation 6 makes the two-way point clear: if the device has two-way capability, it is illegal for high school use even if someone says it is muted. Under NFHS 3-2-5, the one-way communication path is limited to a coach in the dugout or bench area relaying to the catcher while on defense. Read the official 2024 NFHS Baseball Rules Interpretations PDF and the NFHS rule change story.
Watches
Smartwatches we'd start with
If you need to buy into a watch setup, these are the two lower-cost places we'd start first.
Samsung Galaxy Watch5
Galaxy Watch5 is the watch we would start with if you want a dependable Wear OS setup without chasing the newest version. *High school compliant
Watch compatibility note
For CoachCall, we recommend Apple Watch Series 6 or newer, Samsung Galaxy Watch 4 or newer, or a Google Pixel Watch.
Earbuds & Headsets
Audio gear that makes sense on the field
Your typical AirPods and Bluetooth earbuds can work just fine with CoachCall too. If you want open-ear bone conduction options for better field awareness, these are the ones we'd start with.

Catcher Setup
A more catcher-specific receiving path
If you are building for a catcher, we would think less about consumer earbuds and more about a dedicated Bluetooth receiver plus a receiving-only earpiece.
YOCOWOCO Bluetooth Transmitter / Receiver
Best current catcher-side adapter pick for building a receiving-only setup.

Keep it practical
Hardware changes fast, and availability moves around. We'll keep refining this guide as devices change, but the goal stays the same: point coaches toward gear that feels dependable, comfortable, and won't break the bank.
Teams and high school programs should still confirm local association and game-administration expectations before using any electronic communication setup in competition.
