Key specifications of Nothing Headphone (1): In new condition with all its accessories, open to offers. * 🎧 Sound: 40mm dynamic driver, tuned in collaboration with the British audio company KEF. * 🔇 Noise Cancellation (ANC): Active noise cancellation with transparency mode to hear ambient sounds when needed. * 🔋 Battery: * Up to 80 hours without ANC. * Up to 35 hours with ANC enabled. * Fast Charging: 5 minutes gives you about 5 hours of playback. * 📞 Calls: Four microphones with AI technology to enhance voice clarity during calls. * 🎵 Audio Support: Supports LDAC and Hi-Res Audio, and can be used wirelessly, via USB-C, or a 3.5mm jack. * 📱 Multipoint Connection: Connects to two devices simultaneously and switches between them easily. Nothing X App Features: * Adjust noise cancellation level. * 8-Band EQ for full sound customization. * Customize button functions. * System updates (Firmware). * Enable/disable auto on/off when removing or wearing the headphones. * Find your headphones if you lose them. Whether you're using an iPhone, Samsung, or any Android device, all these features work through the Nothing X app and are not exclusive to Nothing phones. If your goal is the best sound quality for 900 SAR, I see it as one of the strongest options. However, if your primary interest is the strongest noise cancellation only, the Sony WH-1000XM6 and Bose QuietComfort Ultra still slightly outperform in isolation. Nothing, on the other hand, stands out with its unique design, physical button controls, excellent app, and balanced sound quality.
