True wireless earbuds have come a long way since the first AirPods launched in 2016. Today, we're comparing two compelling options at different price points - the budget-friendly JBL Tune Flex ($49.99) and the more premium Soundcore Liberty 4 Pro ($129.99). Having tested both extensively, I'll help you understand which might better suit your needs.
Before diving into the specifics, let's talk about what matters in today's wireless earbud market. The technology has matured significantly, with even budget options now offering features that were premium just a few years ago. Key considerations include:
The JBL Tune Flex represents JBL's effort to bring premium features to a more accessible price point, while the Liberty 4 Pro aims to deliver flagship-level performance at a mid-tier price. Released in early 2023 and late 2022 respectively, both incorporate modern features but with different priorities.
The JBL Tune Flex delivers surprisingly good audio for its price point. It uses 12mm drivers (the speakers inside the earbuds) to produce a balanced sound signature with emphasized bass - typical of JBL's house sound. The audio is clear and enjoyable for most genres, though it lacks some of the refinement found in pricier options.
The Liberty 4 Pro takes things up several notches with its dual-driver design, using separate drivers for high and low frequencies (similar to how home speakers often have separate tweeters and woofers). It also supports LDAC, a high-quality audio codec that can transmit about three times more data than standard Bluetooth audio - though you'll need an Android phone to take advantage of this.
In practice, the Liberty 4 Pro offers noticeably better sound separation and detail. Listening to complex orchestral pieces or dense rock arrangements, you can more easily distinguish individual instruments. The bass is punchier but more controlled, and the highs are crisper without becoming harsh.
Active Noise Cancellation has become a standard feature, but implementation quality varies widely. The JBL Tune Flex offers basic ANC that helps reduce low-frequency noise like airplane engines or air conditioners. It's serviceable but not class-leading.
The Liberty 4 Pro steps up with adaptive ANC that adjusts to your environment and provides significantly better noise reduction. It uses multiple microphones to analyze and cancel external noise, making it much more effective in varying conditions. During my testing, it performed notably better on public transport and in busy cafes.
Both models offer competitive battery life, but there are meaningful differences:
JBL Tune Flex:
Liberty 4 Pro:
The JBL Tune Flex uses a traditional stick design similar to AirPods. They're lightweight and comfortable for most users, though they may not feel as secure during vigorous exercise.
The Liberty 4 Pro includes several ear tip sizes and wing attachments for a more customizable fit. This makes them more suitable for athletic activities, though some users might find them slightly bulkier.
Both earbuds support basic touch controls and app customization, but the Liberty 4 Pro offers more advanced features:
The JBL Tune Flex keeps things simpler but still includes essential features like voice assistant support and customizable touch controls.
While neither model is specifically designed for home theater use, the Liberty 4 Pro's LDAC support and lower latency make it a better choice if you plan to use them with your TV. However, for serious home theater use, I'd recommend dedicated wireless headphones instead, as they typically offer better latency performance and battery life.
The JBL Tune Flex delivers impressive value at $49.99, offering most essential features while maintaining good sound quality. They're an excellent choice for anyone entering the true wireless market or wanting a reliable backup pair.
The Liberty 4 Pro at $129.99 justifies its higher price through superior sound quality, better ANC, and more advanced features. They compete with earbuds costing significantly more, making them an attractive option for users wanting premium features without flagship pricing.

Choose the Liberty 4 Pro if:
Both models represent good value in their respective price brackets, but they serve different user needs. The JBL Tune Flex is perfect for those wanting good sound and basic features without breaking the bank, while the Liberty 4 Pro caters to users wanting premium features and superior sound quality at a mid-range price point.
Remember, the best choice depends on your specific needs and budget. If you're unsure, consider how you'll primarily use them and which features matter most to you.
