The JBL 770NC are decent for office use. Their long battery life will easily get you through a workweek without a recharge. You can connect them via Bluetooth using multi-device pairing or via their analog cable.

Listening back to the Tune 770NC, I am quite impressed with the performance JBL is offering at this price. The tuning is fun and engaging and the features being offered make this headphone a versatile choice for someone who wants a portable headphone that can do everything from customize sound to...

Although they won't eliminate every distracting sound, JBL's affordable Tune 770NC headphones are worth considering if you want heavy bass and a comfortable fit.

The JBL Tune 770NC aren't the most exciting of headphones, but they're reliable. They fit well, they're easy to store, have most of the key features you need from a pair of headphones, and they sound good for the price. What more could you want?
