The JBL E50BT are stylish, wireless headphones with a decent sound and a sturdy, durable build. They have a well-crafted design but oddly shaped ear cups that don't fit properly around the ears. Unfortunately, this creates a poor seal that lets noise seep into your audio and also leaks quite a bit.

Our Verdict

0.0
Mixed Usage 

The JBL E50BT are versatile headphones for everyday casual use. They have an above-average and decently balanced sound. They're also robustly built and seem durable. Unfortunately, the awkward fit of the ear cups poorly isolate listeners from ambient noise and they also leak a lot.

Pros
  • Above-average audio reproduction.
  • Sturdy and durable build.
  • Great wireless range.
Cons
  • Poor noise isolation.
  • Leaky at moderate-to-high volumes.
  • Awkward ear cup fit can be uncomfortable.
  • Bass delivery varies significantly across users. Sensitive to glasses.

Neutral Sound 

Above-average for neutral listening. These headphones have a good bass, a decent midrange and a moderately spacious soundstage for a closed-back model. They sound punchy and have a satisfactory amount of detail with instruments and vocals. However, they lack a little warmth and are a bit uneven for pure neutral listening.

0.0
Commute/Travel 

Subpar for commuting. The odd fit of the ear cups lets a lot of ambient noise seep into your audio which won't be ideal for loud, noisy environments.

0.0
Sports/Fitness 

Decent for sports use. The JBL Synchros E50BT have a great control scheme, a moderately stable fit, and a good wireless range that covers a large area, especially outdoors in direct line of sight. Unfortunately, they're a bit too bulky, to comfortably exercise with.

0.0
Office 

Mediocre for office use. If you can get a good seal, these headphones won't leak too much. However, they poorly isolate you from ambient noise and won't be the best headphones to use in a lively or noisy office.
