Key Features to Look for in Wireless Headphones:
* Connectivity (Bluetooth):
* Bluetooth Version: Look for Bluetooth 5.0 or higher (e.g., 5.3). Newer versions offer more stable connections, longer range, and better power efficiency.
* Codecs: This is crucial for sound quality. Common codecs include:
* SBC (Subband Codec): Standard, universal, but lower quality.
* AAC (Advanced Audio Coding): Better quality, especially good for Apple devices.
* aptX (and variants like aptX HD, aptX Adaptive, aptX Lossless): Offers higher fidelity, popular with Android devices.
* LDAC: Sony's proprietary codec, capable of transmitting near-High-Resolution Audio wirelessly (requires compatible source device).
* LHDC/LC3: Emerging codecs offering high quality and low latency.
* Note: Both your headphones and your source device (phone, laptop) need to support the same high-quality codec to take advantage of it.
* Sound Quality:
* Driver Size: Larger drivers (e.g., 30mm for over-ears, 10-14mm for earbuds) can potentially produce fuller, more impactful sound, but it's not the only factor. Tuning and design are just as important.
* Frequency Response: The range of frequencies the headphones can reproduce (e.g., 20 Hz to 20,000 Hz for standard human hearing). A wider range might indicate more detail at the extremes.
* Sound Signature: Do you prefer a bass-heavy sound, a neutral and balanced sound, or something with sparkling highs? Reviews often describe this.
* High-Resolution Audio Support: Some headphones and codecs (like LDAC or aptX HD) claim to support "Hi-Res Audio Wireless," meaning they can transmit more data to preserve more of the original recording's detail.
* Active Noise Cancellation (ANC) & Transparency Mode:
* ANC: Uses microphones to detect
