I disagree that modern headphones have the same naming issues.

They have an unnecessary blast of letters and numbers in comparison to some others. Even though others have long names they are still better because it is somewhat natural in terms of Brand>Product Line> Current Product.

• Sony WF-1000XM5
• Bose QuietComfort Ultra Earbuds (2nd Gen)
• Technics EAH-AZ100
• Sennheiser Momentum True Wireless 4
• Samsung Galaxy Buds 3 Pro
• Google Pixel Buds Pro 2
• Anker Soundcore Liberty 4 NC
• Nothing Ear (a)

Again with the phones, I was actually wrong. Sony used to use the letters to show their range and it was again unreasonable but we all recognised that Z was the flagship. Now they use Xperia as Brand then 1, 5 or 10 to show place in the range and then Roman numerals to show their iteration within the range.

Sony Xperia 1 VII which is spoken as "Sony Xperia One Seven" which creates an issue with current naming conventions to align with years so they appear 8 years behind the Samsung Galaxy S25.

Sony Should be selling the Xperia 25, 25 Pro and 25 Ultra or some variation or play on this. If they want to stand out fair enough but its not like they are.
