If you want a pair of ultra-light on-ear headphones you can wear all day with hands-free calling and tap-to-pair convenience, choose August EP636; if you need truly wireless in-ear buds that stay put during workouts and shrug off sweat and rain, choose Jxrev Earbuds.
• August EP636 biggest strength: A 126-gram on-ear design with padded ear cushions and a cushioned headband that's built for long, comfortable wear, plus NFC tap-to-pair and Multipoint so two devices stay connected at once.
• August EP636 biggest trade-off: It's a traditional on-ear headphone with no water-resistance rating, no active noise cancellation, and it charges over the older Micro USB connection.
• Jxrev Earbuds biggest strength: Bluetooth 5.3 with auto-pairing, 13mm drivers, IP7 waterproofing, and a pocket-sized USB-C charging case that extends total playtime to 32 hours.
• Jxrev Earbuds biggest trade-off: The tiny in-ear fit isn't for everyone, and the "noise cancelling" here is call noise cancellation plus sound isolation rather than full active noise cancellation.
• Who August EP636 is for: Anyone who wants one comfortable pair of headphones for commutes, night shifts, and desk work, and who likes leaving their phone in a pocket or bag.
• Who Jxrev Earbuds is for: Gym-goers, runners, and riders who want sweat-proof buds that disappear in their ears and never tangle.
The August EP636 is an on-ear Bluetooth headphone that solves one problem really well: staying comfortable for hours. At 126 grams, it's genuinely light for an on-ear model, and August backs that up with soft padded ear pieces and a cushioned headband. If you've ever had a heavier headphone press on the top of your skull after two hours, you know why that matters. The earcups rotate and the headband extends, so it's easier to dial in a fit that doesn't clamp too hard.
Feature-wise, it's a practical daily driver rather than a spec sheet show-off. Bluetooth 4.1 with up to 10 meters of range covers the normal walk-away-from-your-desk scenario. NFC pairing means you can tap an NFC-enabled phone or tablet to connect instead of digging through Bluetooth menus. Multipoint is the quiet hero here: you can have a laptop and a phone connected at the same time, so you can watch a movie and still take a call without repairing anything. When one device is active, the other pauses automatically.
Battery life is rated at up to 12.5 hours on a 2.5-hour Micro USB charge, which comfortably covers a long shift or a full commute week if you charge on weekends. The built-in microphone and on-board buttons handle calls and music without touching your phone.
Jxrev Earbuds: Who It's For
The Jxrev Earbuds are the opposite philosophy: get out of the way and stay in your ears. Each bud weighs about 3 grams, lighter than a sheet of paper by Jxrev's own framing, and the charging case is small enough to live in a coin pocket. Bluetooth 5.3 handles the connection with auto-pairing: open the case, and the buds hook up to your phone without you touching a menu. Range is listed at 10 meters, same as the August.
For sound, Jxrev uses 13mm dynamic drivers and rates the frequency range from 20Hz to 20,000Hz, which is the full audible band. That's the kind of driver size you'd normally associate with punchier bass, and the tuning is described as bass-forward with clear mids. Each earbud has its own mic with call noise cancellation, so phone calls are usable outdoors, though the "noise cancelling" claim here is about calls and passive sound isolation, not the active noise cancellation you'd find on premium over-ears.
The sports angle is where these earn their place. IP7 waterproofing plus an internal nano-coating means sweat, rain, and splashes are not a problem, and the ergonomic rounded-tip shape is designed not to protrude from your ear. You get three listening modes worth knowing about: binaural for full stereo, sharing mode to hand one bud to a friend, and monaural for wearing a single bud while driving. Touch controls on both ears handle volume, track skipping, play/pause, calls, and voice assistant. Battery is rated at 6 to 8 hours per charge and 32 hours total with the case, which tops up in about 1.0 to 1.5 hours over reversible USB-C.
Who should buy it: runners, gym regulars, cyclists, and anyone who wants buds they can forget about. Who should skip it: if you prefer the acoustic feel of a real earcup, want physical buttons instead of touch, or need a full active noise cancelling experience for flights.
Side-by-Side: Which Should You Choose?
• Best for workouts and weather → Jxrev Earbuds. IP7 waterproofing and a secure in-ear fit are exactly what the August lacks.
• Best for battery endurance → Jxrev Earbuds. 32 hours total with the case beats the August's 12.5 hours, though the August is one continuous charge.
• Best for call handling with multiple devices → August EP636. Multipoint keeps a phone and laptop connected at once, with automatic pausing.
• Best for bass and compact sound → Jxrev Earbuds. 13mm drivers with a 20Hz low end reach deeper than the August's 80Hz floor.
• Best for charging convenience in 2026 → Jxrev Earbuds. USB-C beats the August's Micro USB, plain and simple.
• Best for people who dislike things inside their ears → August EP636. On-ear is a fundamentally different sensation.
• Best for sharing audio → Jxrev Earbuds. Sharing mode lets two people listen from one source.
In my opinion, the Jxrev Earbuds are the better buy for most people in 2026. The combination of Bluetooth 5.3, IP7 waterproofing, 32 hours of total playtime, USB-C charging, and a genuinely pocketable case covers more real-world situations than the August EP636 manages. The August still wins on one thing that matters: if you want an on-ear headphone you can wear for a full shift without your ears aching, and you value Multipoint and physical buttons, it's the more comfortable everyday companion. So my call is simple: pick the Jxrev for movement, sweat, and battery; pick the August for long stationary listening sessions and dual-device juggling. Either way, check the current price on Amazon before you commit, since both sit in the budget tier and the gap can swing your decision.
FAQ
Not necessarily better, but different. The August has a single built-in mic with on-board call buttons and Multipoint, which is handy if you're switching between a laptop and phone. The Jxrev puts a mic in each bud with call noise cancellation, which usually helps more in windy or noisy outdoor settings.
Yes, that's their main design goal. They carry an IP7 waterproof rating with an internal nano-coating for sweat and rain. The August EP636 has no water-resistance rating, so I wouldn't wear it for hard workouts or in the rain.
The August EP636 runs up to 12.5 hours continuously on one 2.5-hour charge. The Jxrev Earbuds give 6 to 8 hours per charge but reach 32 hours total using the case, which recharges in about an hour via USB-C.
