It’s been a few years since my last RS tour. Are the tours using Bluetooth tech yet? Can I use my wireless earbuds for the tour? If not I’m assuming a wired earphone will be best- but what adapter? With the Lightning work?
We were on a tour in August 2019 which is close to the end of tours offered before Covid hit and no, there was no Bluetooth.
I use an Apple adapter or dongle for my wired headphones. Lightning to 3.5 mm plug
Edit: They can be easy to lose so you might want spares.
I would take along a wired set also. Every museum audio guide has a headphone jack so you don't have to hold the thing like a phone. The range for bluetooth might make using it for groups impractical. I haven't flown in two years now, are planes using bluetooth or would the wired be useful there as well?
I mentioned onboard headphones in a recent post, on Delta you need wired phones unless, according to some, you buy a little dongle that transmits to your headphones. But why bother with that, esp. if the pilot comes running into the cabin saying who is messing with my instrumentation? In my experience most wireless over the ear phones have the ability to be plugged in with the included cord.
FWIW, we took a river cruise in Strasbourg and everyone was given cheap red wired earbuds. I was just going to keep and reuse (or recycle) mine but as we were exiting, there was a bin where you were to toss them "for recycling." Hopefully they will follow through.
The dongles are great but it's another thing to keep charged, last 4-8 hours on a charge and many won't operate while charging. I'd always rather have my own wired headphones than use (recycled?) freebies.
