Differences between Hammerhead True Wireless and X

Hello Razer! I have a question about what are the differences between Razer Hammerhead True Wireless Earbuds (2019) - Black and Razer Hammerhead True Wireless X. Because I really like the design without ear tips and that they are wireless. I have looked at the details of the products available on your website that provide good information, but I am missing which of them is the newest. I have also looked around to see a review between these two products but can not find any. Either they are review between other products or between the other two wireless with ear tips. Would you be able to give information about which of Razer Hammerhead True Wireless Earbuds (2019) - Black and Razer Hammerhead True Wireless X is more worth buying as I am very new to gaming and my budget is slim? I also wonder if you are working on a new/updated version of the product with no ear tips, if it might be better to wait to buy it? Thank you so much for the help in advance! Merry Christmas and a Happy New Year!
