witch Bluetooth earphones will conect with the watch
Most BT LE devices should work, but some work better than others. Price seems to not be a factor as the cheaper ones often seem to work better than the expensive ones. This is due to the fact that cheap models are more likely to use the base BT protocols and not customize them for advanced features or settings like more expensive models do (and there is no way of knowing if a manufacturer has tweaked the protocols to take them out of compliance). The BT standard is in such a way a 'standard' that it can be widely interpreted with different settings for buffer sizes, time outs, profiles, protocols, antenna configurations, etc.. TomTom cannot change their code every time a manufacturers messes with the BT coding. This is a case where paying more will not increase the chances of connectivity, it may actually decrease it. There are thousands of models out there so there is no way for TT to test them all and since the manufacturers often tweak the BT settings there is no way to know upfront if a pair will work or not. At a minimum they need to be BT LE and support A2DP and AVRCP, the two protocols necessary to play music. Your best bet is to buy them from someplace with a good return policy so if they don't work you can return them and try another brand.
I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
