Solo 4 wireless on-ear headphones Slate Blue

The Solo 4 on-ear headphones in Slate Blue deliver wireless Bluetooth audio for Apple and Android users. Up to 50 hours of battery life supports long listening sessions without frequent recharging. Custom acoustic architecture and updated drivers provide powerful Beats sound. Designed for adults, teens and kids seeking portable personal audio.

Upgrade from wired or older Bluetooth headphones

Replacing a wired set removes cable tangles and adds freedom of movement. Moving up from an earlier Bluetooth model gains the extended 50-hour runtime and improved driver tuning. The jump is worth it when you need all-day battery and a balanced sound signature without active noise cancellation.

Simple pairing and fit adjustments

Bluetooth pairing works with both Apple and Android devices in seconds. The on-ear design rests on the ears rather than sealing the canal, so comfort depends on personal preference. Some users find on-ear pressure tiring after several hours; trying the fit before extended use avoids discomfort.

Questions about this item

Will the 8.23 × 5.2 × 3.7 inch dimensions fit my head comfortably?

The on-ear cups measure 8.23 by 5.2 by 3.7 inches and weigh only 0.07 pounds, so they sit lightly without clamping pressure.

How do I pair the Bluetooth connection and what step do people skip?

Hold the power button until the LED flashes, then select the headphones in your device’s Bluetooth menu; many forget to enable pairing mode first.

When will the internal lithium-ion cell need replacing after daily 50-hour cycles?

The single lithium-ion cell is rated for hundreds of full charges; expect several years before capacity drops enough to require service.
