Experience Sound, Reimagined.

Introducing the UGREEN HiTune S3, the wireless earclip earbuds designed for those who want to stay connected to their world without sacrificing audio quality. Featuring an innovative open-ear design, the HiTune S3 rests securely on the edge of your ear, delivering rich, directional audio without blocking your ear canal. This allows you to enjoy your music and calls with crystal clarity while maintaining full situational awareness—perfect for outdoor activities, commuting, or working in a busy environment.

All-Day Comfort & Unwavering Stability

Crafted from skin-friendly flexible silicone and weighing a mere 5.3g each, the HiTune S3 earbuds provide a 'zero gravity' feel for comfortable, all-day wear. The ergonomic C-shape earclip design ensures a secure and stable fit, adjusting to your ear shape to stay in place during your most active moments, from a morning run to a rigorous gym session.

Superior Audio & Crystal-Clear Calls

Don't let the open-ear design fool you. The HiTune S3 is equipped with large 12mm bio-diaphragm dynamic drivers that produce deep, powerful bass and crisp, clear highs for an immersive listening experience. Directional audio technology minimizes sound leakage, focusing the music on you. For calls, dual microphones with AI-powered Environmental Noise Cancellation (ENC) filter out background noise, ensuring your voice is heard with exceptional clarity, making conversations feel like they're happening face-to-face.

Not quite as good as top name brands but pretty decent so far for the money
Style: 7" Swim Trunk, Color: Black, Size: Large
I compare these to the Columbia version with similar design. I ordered the large, which is my Columbia size. I note that the Amazon version was slightly tighter in the waist and the lining was significantly tighter in the legs. The elastic bands are both well structured and not flimsy. I live in Florida and I wear these swim trunks as my everyday outdoor shorts, whether working in the yard, biking, walking, or whatever. I note that when I tried to wear these in my exercise classes, the legs tend to stick and not slide up the legs when I squat, which is not a problem with the Columbia shorts. Lest you think it unfair to compare these two brands, Columbia puts their shorts on sale a couple of times a year for about the same price. Of course, you have to pay attention regularly to their website and it doesn't help if you need shorts now. I will continue to use these shorts for outdoor work and activities and they seem to be holding up fine for now. Next time I will probably get the XL for comfort if Columbia doesn't have a big sale (unless I can manage to lose a little visceral fat I have collected the last few years!). One other positive and one negative. I like that the black shorts have a black tie string, but the blue pants have a white string which shows dirt and looks a bit cheaper than if the string was blue. White is fine for swim trunks, but when they are used as all purpose volley shorts it doesn't show well with white string. I saw some complaints in the comments saying these shorts were not quick drying. I note they are every bit as fast drying as my Columbia and Nike shorts which are advertised as quick drying. As you might imagine a few hours working in the Florida sun I can sweat a ton so I can certainly judge drying speed.
