JBL Tune 520BT Review

Skip these. The comfort is among the worst we've tested (4th percentile), making them painful for extended use. While the 57-hour battery and app support look good on paper, the muddy, bass-heavy sound and cheap feel don't justify the $40-$50 price when better all-rounders exist.

The JBL Tune 520BT is a straightforward, budget-friendly pair of wireless on-ear headphones. You're getting a simple package here: Bluetooth 5.3 for a stable connection, a massive 57-hour battery life, and JBL's signature bass-heavy sound profile. It's a no-frills option that promises to get the job done without draining your wallet. For about $40 to $50, it's positioned as an entry point into the JBL ecosystem, offering features like multi-point connectivity and a companion app for EQ tweaks, which is rare at this price.

Let's talk numbers. The sound quality lands in the 36th percentile in our database, which means it's below average. The 'Pure Bass' marketing is accurate—expect a lot of low-end thump that can muddy up mids and highs. The microphone is about average, sitting at the 53rd percentile, so it's fine for quick calls but don't expect studio clarity. The real standout, on paper, is the battery life. However, its 57-hour rating only hits the 14th percentile. That tells us most competitors in this category are doing even better, so what seems like a strength is actually a relative weakness. Active noise cancellation isn't a feature here, so that 36th percentile score reflects the basic passive isolation you get from on-ear cups.

Priced between $40 and $50, the Tune 520BT is firmly in the budget category. You're paying for the JBL brand name and a specific set of features—long battery and app support—over pure audio fidelity or comfort. For the money, you can find other options with better sound or much better comfort, but you might sacrifice that app control or multi-point connectivity. It's a trade-off, not a steal.

Stacked against its real competitors—other budget wireless headphones—the Tune 520BT's weaknesses become clear. Its comfort score is one of the worst we've seen, while something like the Anker Soundcore Life Q20 often scores much higher for a similar price. For sound, it lags behind models like the Sony WH-CH520, which offers a more balanced profile. Its one clear advantage is the JBL Headphones App for EQ, a feature many budget rivals skip. If app control is a must-have for you under $50, it has a niche. Otherwise, you're making a comfort compromise.

Anyone who plans to wear headphones for more than an hour at a time should look elsewhere. The comfort score is a deal-breaker. Also skip if you prioritize clear, balanced audio over heavy bass, or if you need effective noise cancellation for commuting or travel. These are strictly for very casual, short-burst listening where app-based EQ control is your top priority.

We can't recommend the JBL Tune 520BT for most people. The deal-breaking issue is comfort, which sits in the dismal 4th percentile. A headphone you can't wear for more than 30 minutes isn't a good headphone, no matter how long the battery lasts. Combine that with below-average sound and build quality, and the value proposition falls apart. Only consider these if you absolutely need the JBL app for EQ tweaking on a tight budget and you have a high pain tolerance for on-ear pressure.
