Nothing, the First Line version is simply discounted for LE.

Absolutely nothing, The stock of each unit dictates the price.

Hi Chris and welcome. There is no difference. Buds' prices are tied to stock level and higher stock same or similar items will be lower in price and vice versa. Cheers, stay safe and enjoy!

Good evening to you!! The difference is how many of each are in stock. The more of one will make the price lower. The less will make it more expensive. Other than that I see nothing. Have a good rest of your day.
