Our AI advisor analyzes real-time pricing across all channels to find you the best deal.
AI Verdict
These are 0.353-ounce wireless earbuds with 12mm drivers and 32 hours of total battery life, best for casual listening where strong noise cancellation isn't a priority.
The earbuds offer both open and sealing ear tips, providing flexibility for different preferences. However, many users report that neither type creates a sufficient seal, which compromises both sound quality and the already weak Active Noise Cancellation. While comfortable for some, others find they don't stay in during movement.
If a secure, isolating fit is crucial, look for earbuds with multiple silicone tip sizes and a design specifically engineered for a deep, consistent ear canal seal.

What Buyers Say
The most surprising recurring issue with the JBL Tune Flex isn't just the weak Active Noise Cancellation, but the widespread complaints about the charging case. Many users report that the earbuds frequently fail to charge properly due to loose connections, often requiring constant wiggling or cleaning, which makes them unreliable for daily use. This charging problem often leads to dead earbuds when needed, overshadowing the otherwise praised sound quality and flexible ear tip options. The ANC is consistently criticized for being ineffective, barely reducing noise even in quiet environments.
“These earbuds are driving me nuts, the sound is actually pretty good for the price but I can't even get them to charge half the time, they just sit there dead in the case and then connect to my phone when I don't want them to.”

Frequently Asked Questions
Do these earbuds have effective noise cancellation?
No, user feedback consistently indicates that the Active Noise Cancellation is weak and only minimally reduces ambient noise, often failing to block out common sounds like fans or conversations.
How long does the battery last?
The earbuds offer up to 32 hours of total battery life, with 8 hours in the earbuds and an additional 24 hours from the charging case. With Active Noise Cancellation engaged, you get 6 hours from the earbuds and 18 hours from the case.
Are they good for phone calls?
They feature 4 microphones for calls and VoiceAware technology, allowing you to hear your own voice. While some find them adequate, others report mic quality could be better.
Can I use them for working out?
Yes, they are IPX4 water resistant and sweatproof, making them suitable for light workouts. However, some users report they may not stay in during more vigorous activities like running.
What kind of ear tips do they come with?
The JBL Tune Flex includes both open-style ear tips and traditional in-canal sealing ear tips in multiple sizes, allowing you to choose based on your preference for awareness or isolation.
Buying Guide
When looking at earbuds, you need to think about how they'll actually sit in your ears and what sounds you need to block out. Earbuds with active noise cancellation (ANC) use microphones to cancel out external sounds, but how well they do this depends a lot on the earbud's design and how well it seals in your ear. A poor seal means even the best ANC won't work right. Also, consider the total battery life, which includes both the earbuds themselves and the charges stored in their case.
Active Noise Cancellation (ANC)
This feature uses microphones to detect external sounds and then emits an 'anti-noise' signal to cancel them out. It's crucial if you want to reduce distractions from airplane engines, bus rumble, or office chatter, but its effectiveness varies wildly between models.
Driver Size (e.g., 12mm)
The driver is like a tiny speaker inside the earbud. A larger driver (like 12mm here) can often move more air, which can contribute to a fuller sound, especially in the bass frequencies, making your music feel more impactful.
IPX4 Water Resistance
The 'IPX4' rating means the earbuds are protected against splashing water from any direction. This is important if you plan to use them during workouts where you'll sweat, or if you might get caught in light rain, preventing damage from moisture.
Total Battery Life (e.g., 32 hours)
This number tells you how long you can use the earbuds before needing to plug the case into a charger. It combines the playtime of the earbuds themselves (e.g., 8 hours) with the extra charges the case can provide (e.g., 24 hours), so you know how many full listening sessions you get on the go.
Alternatives
If you need effective noise cancellation and a consistently reliable charging experience, look for earbuds with a strong, consistent ear canal seal and user reviews specifically praising charging stability.
