The JBL Endurance Run is a pair of in-ear style headphones which focuses on providing a tight grip when worn so as to prevent slipping out of your ears while performing intensive activities like running or jogging or exercising in the gym. They’re also sweatproof so having them on while you’re busy burning calories shouldn’t cause any issues. The earplugs themselves are soft to touch and feel like they’re made of rubber or silicone and feel much more premium than a regular plastic construction.
The ear tips are removable and can be changed as per your preferred size from the small, medium and large options provided within the package. The buds are also angled to ensure a tight fit. The rear side of the buds sports the JBL branding along with a pair of magnets which can be used to attach the two earbuds together when not in use. Also, thanks to the unique design, the earphones can be worn in two different ways – the first one being how you would wear a normal set of earphones. Second, from behind your ear which gives you an extra secure fit.
JBL has used the same soft-touch material in the construction of the wire too, however, due to the absence of a flat-style cable, the earphones get tangled up more often than you would want them to when stuffed into your pockets or a backpack. The 3.5mm connector is angled and gold plated which is a nice touch. There is an inline microphone with a push button to play/pause music but the button itself is extremely mushy and hard to press. The microphone quality is average which brings me to the inference that if you make a lot of phone calls using earphones, the JBL Endurance Run is not for you.
Speaking about the most important aspect, the audio quality on these earphones, being sports or action-oriented, the bass is heavy on the Endurance Run and if you listen to a lot of EDM or hip-hop, you will be pleased with the sound output. The vocals, however, are not that clear meaning if you listen to songs with lots of vocals or audiobooks or podcasts, you’ll not have the best experience. The volume on these earphones is adequate but if you listen to music at extremely loud volumes then the Endurance Run isn’t the best option out there. That said, the overall sound quality isn’t too shabby, but it surely could’ve been better for the asking price.
