Connectivity is largely matched between these two, with the critical distinction lying in high-resolution codec support. The boAt Nirvana X supports LDAC, Sony's high-resolution Bluetooth codec capable of transmitting up to 990 kbps — significantly more audio data than standard Bluetooth, making it relevant for listeners using hi-res audio sources on Android devices. The Noise Air Buds Pro 6, by contrast, supports LDHC, a competing high-res codec with similar ambitions but notably narrower device ecosystem support. Both codecs target audiophile-grade wireless transmission, but LDAC enjoys considerably broader compatibility across Android smartphones and music apps, which is a practical advantage for most users.
Beyond the codec difference, the two products are effectively identical in this category. Both offer AAC support for Apple device users, fast pairing, USB Type-C charging, a maximum Bluetooth range of 10 m, and fully wireless operation. Neither supports aptX variants, NFC pairing, Bluetooth LE Audio, or Auracast — so there are no surprises on either side in those areas.
The boAt Nirvana X holds a moderate edge here, specifically for Android users who want high-fidelity wireless audio. LDAC's wider adoption means more devices and apps will actually leverage the codec, whereas LDHC support on source devices remains comparatively limited. For AAC-dependent Apple users, however, both products stand on equal footing.
