Solo 4 On-Ear Headphones

The Solo 4 on-ear headphones are a new wireless set from Beats. They use a custom acoustic architecture and updated drivers to deliver powerful sound. A built-in lithium-ion battery provides up to 50 hours of listening time. The matte black finish gives them a low-key look.

Who these suit and who they don't

They suit listeners who want long battery life and wireless freedom without a cable. Voice control and media buttons let you manage playback hands-free. They are not for buyers who need active noise cancellation to block outside sound. They also do not suit anyone who prefers a traditional over-ear fit.

Battery life and charging

The internal battery reaches 50 hours on a full charge. Recharging takes 135 minutes from empty. A quick top-up gives useful listening time when you are in a hurry. The pack contains 10 watt-hours of energy.

Questions about this item

How do I pair these Solo4 headphones with my phone using Bluetooth?

Enable Bluetooth on your phone, power on the headphones, and select "Beats Solo 4" from the available devices list to connect wirelessly.

What battery maintenance will these headphones need over time?

The built-in lithium-ion battery provides up to 50 hours per charge and recharges in 135 minutes; battery capacity will gradually decrease after many charge cycles.

What limits listening time during a single long session?

Battery life is rated at 50 hours per full charge, so extended continuous playback will eventually require recharging the internal battery.
