What Common Both Can Do?

• Over-ear, closed-back design: Both headphones use an over-ear, closed-back form factor. This ensures good passive isolation and a comfortable fit over the ears — useful for immersive listening or noise isolation even before ANC is turned on.
• Wireless (Bluetooth) connectivity: Both models connect via Bluetooth, making them convenient for wireless use with phones, laptops, or tablets. This removes the need for cables during everyday listening and supports portability.
• Active Noise Cancelling (ANC): Both support ANC, allowing users to reduce ambient noise when listening in noisy environments like public transit or busy streets. It helps deliver a more focused listening experience.
• Ambient Aware mode: Both allow ambient-sound modes that let in some external sound — useful when you want situational awareness (e.g. hearing traffic or announcements) without removing the headphones entirely.
• Built-in microphone(s) for calls: Each model includes onboard mics so users can take phone calls or attend meetings hands-free. That adds versatility beyond just music listening.
• On-ear controls (buttons or touch): Both have controls (on earcups) for play/pause, volume, and call handling. This enables easy control of playback or calls without reaching for the connected device.
• Rechargeable battery (internal): Both use an internal rechargeable battery rather than disposable ones — giving flexibility to recharge and reuse, which is practical for travel and daily commuting.
• Foldable headband design: Both have adjustable headbands and folding hinges: making them adaptable to different head sizes and easier to store or carry, which is important for portability and comfort.
• Multipoint support (single-device pairing + switching): Even if newer multipoint enhancements differ, both at minimum pair over Bluetooth and support typical device switching — offering flexibility to move between phone, laptop, or tablet.
• Auxiliary (wired) input support: Both offer a wired input option for when Bluetooth is unavailable or battery is low — ensuring listening options remain even if wireless isn’t ideal.
• Audio playback via Bluetooth (streaming): Both support streaming music wirelessly over Bluetooth — the core function of wireless headphones — so users get wireless music enjoyment regardless of model.
• On-headphones portability (fold-flat + carrying ease): Both are designed to fold and be reasonably portable, making them suitable for commuters, travelers, or anyone who wants easy storage or packing.
