The Relays are ready to run right from the start, as The Wirecutter finds they "popped immediately into place" and "stay put without chafing or tugging." Pocket-Lint notes that each headphone "moulds to your ear as you put it in," which Digital Trends says "felt a little invasive at first, but we soon got used to it." The Relays are sweat- and water-resistant, which makes them ideal for many outdoor situations, and The Wirecutter notes that they are more than up to "the abuse that fitness headphones face on the daily."
Being tough doesn't mean a thing if you can't count on the Relays to deliver your favorite tunes while you exercise, and Pocket-Lint reports that they sound "marvellous," though "purists need not apply." ChipChick says the Relays are "a bit on the bassy side, but theyâ€™re very clear and rich in detail."
While fitness headphones usually involve some kind of compromise in comfort, durability or sound, the Sol Republic Relays deliver high marks across the board, making them an ideal exercise companion.
