Budget IEMs with "Sublime" Sound: JBL Endurance Run Praised
Users on r/headphones have expressed surprise at the sound quality of JBL Endurance Run models, describing it as clear with well-controlled bass and mids. The audio signature is noted to follow the Harman curve with added bass, making it suitable for genres like metal music.
Mixed Longevity Reports: From "Bomb Proof" to Early Failure
User experiences with JBL Endurance models vary regarding durability. Some users report their earbuds lasting for years with weekly washing due to sweat, calling them "bomb proof." Conversely, others have experienced failures within months, attributing it to sweat exposure.
Secure Fit: Essential for Runners and Active Users
For active users, the secure and stable fit of JBL Endurance headphones is a recurring positive point. Features like TwistLock are credited with keeping the earbuds in place during intense running and other dynamic activities.
Connectivity Hiccups Reported by Some Users
A subset of users on r/JBL have encountered connectivity issues with the Endurance Run 3, experiencing devices that fail to connect or become undiscoverable after minimal use. Standard troubleshooting methods have not always resolved these problems.
Strong Value Proposition in Budget IEM Market
The JBL Endurance Run series is frequently cited as a strong contender in the budget in-ear monitor market. Users find them to be "damn nice" alternatives that offer excellent sound balance and performance, often comparing favorably to more expensive options.
Expert answers based on real user experience
The JBL Endurance Run 3C feature an IP65 rating, meaning they offer a high level of protection against dust ingress and are resistant to water jets. This makes them suitable for intense training sessions where sweat accumulation is common, or for use in dusty environments such as gravel trails. While not designed for submersion, the IP65 standard provides confidence that they can withstand direct water spray and heavy perspiration without performance degradation. This level of resilience is a key differentiator from models lacking such certification.
Product Specifications
These headphones are engineered with JBL Pure Bass Sound and are Hi-Res certified, powered by 8mm dynamic drivers. Users have noted a sound signature that closely aligns with the Harman target, offering clear bass, a controlled midrange, and a slightly elevated mid-treble. This balance is often described as "sublime" for genres like metal, providing the energetic low-end that can enhance workout motivation without overwhelming the rest of the mix. The 8mm drivers deliver a detailed audio experience suitable for focused training.

Yes, the JBL Endurance Run 3C incorporate TwistLock technology, designed to create a lightweight and ergonomic fit that ensures stability during dynamic movements. This technology aims to provide a secure seal within the ear canal, preventing the buds from dislodging. Additionally, FlipHook technology offers versatility, allowing wearers to choose between an in-ear or behind-the-ear configuration for a customized and stable fit, even during high-impact activities like running or jumping.
Product Features
While many users report positive experiences with the sound and fit, some discussions have highlighted occasional connectivity challenges. A few users have reported instances where the headphones failed to connect after initial use or exhibited intermittent connectivity issues, indicated by a single blue light. Standard troubleshooting steps have not always resolved these specific instances. However, other users have noted good longevity, with some older JBL Endurance Run models lasting several years despite significant wear.
r/JBL, r/headphones user discussions
The JBL Endurance Run 3C are specifically designed for sport and high-intensity workouts. Their IP65 dustproof and water-resistant rating makes them resilient against sweat and light moisture, ideal for gym sessions, running, or cycling in varied conditions. The secure fit provided by TwistLock technology ensures they remain stable during vigorous movements. The JBL Pure Bass sound signature is also tuned to provide an energizing audio experience that can help maintain motivation during demanding physical activities.
Product Features & r/running user discussions
A key distinction is the IP65 dustproof and water-resistant certification on the Endurance Run 3C, a feature absent in the Endurance Run 2. While users generally find the audio quality similar between the two, the Run 3C might feel slightly less premium in its build compared to the Run 2. However, some users suggest the Run 3C could offer improved comfort for longer wear periods. Unlike the Run 2, the Run 3C does not typically include a carrying pouch.
