I should also check similar models from 2021 to ensure my specs are realistic. For example, the JBL Flip 5 from 2021 has 12 hours, while the Sone127 might have a similar or slightly different range. Connectivity features like Bluetooth 5.0 are standard since around 2019.

: Check online retailers like Amazon, Best Buy, or the Sone official website for current pricing. Warranty : Standard 1-year warranty with optional 3-year extended coverage.

I should also think about possible user questions not covered in the review. For example, does it support NFC, or has there been any firmware updates? But without actual data, I can't include those. Stick to the most likely features based on the brand and year.
