JBL Xtreme 4 vs Sony ULT FIELD 5

For most people the JBL Xtreme 4 beats out the Sony ULT FIELD 5, but it may depend on quality of life differences. The JBL manages to nearly double the battery life of the Sony, and yet, it weighs noticeably less at 2.1 kg (4.7 lbs), compared to the Sony at 3.3 kg (7.3 lbs). Despite the lighter weight, both reach comparable max output volumes, and build quality is similar: both are rated IP67 against dust and water. You can tweak the tuning on either using the EQ in-app, with the JBL sounding a bit weaker in the bass (by default), but more even in the mids, while the Sony boosts high-bass and treble for a more excited sound. The Sony has lower latency, and it supports LDAC for higher-quality audio streaming, and it has RGB lighting, which you might like. Its 'Stamina' mode disables tuning features and extends the battery life considerably. It'll also float, unlike the JBL.
