A/B Test Headline Generator for E-commerce

I need 5 A/B test headline variations for a premium organic coffee brand targeting environmentally conscious millennials. The goal is to highlight the sustainability and ethical sourcing of the coffee beans. The tone should be authentic and trustworthy, and the headlines should be concise and attention-grabbing for online shoppers. Consider highlighting benefits like 'eco-friendly,' 'sustainably sourced,' 'ethically grown,' 'rich flavor,' and 'guilt-free indulgence.' Please provide headlines suitable for use on product pages and in email marketing campaigns. Try to include a question in at least one of the headlines.

Create 5 A/B test headline options for a new line of noise-canceling headphones aimed at remote workers. The key selling points are superior noise cancellation, comfortable fit for extended use, and crystal-clear audio quality for calls and music. I'd like at least one option to focus on productivity benefits (e.g., 'Focus better, work faster') and another highlighting the comfort aspect (e.g., 'Comfortable all-day wear'). Avoid overly technical jargon. Generate some that highlight the benefit to remote workers who have to handle a lot of calls. All options should be under 60 characters.
