Know before you buy
The 'XR' stands for Extended Response, which indicates that these earphones are tuned to provide a more pronounced bass presence compared to the standard model, while still maintaining the brand's signature clarity in the mids and highs.
Yes, they are excellent for noisy settings. The design provides up to 42dB of passive noise isolation, which effectively blocks out a significant amount of ambient sound without requiring active noise cancellation.
You can use them for calls. The included cable features an inline remote and microphone, allowing you to manage phone calls and playback controls easily.
The filters act as a protective barrier that prevents earwax and debris from entering the internal drivers. Replacing them periodically ensures the earphones maintain their original sound quality and longevity.
