• APZXTRK 2-in-1 biggest strength: two complete pairs of earbuds in one box — a half in-ear set for active use and a flat over-ear set built for side sleepers — plus a charging case with a digital battery display.
• APZXTRK 2-in-1 biggest trade-off: it's a two-piece system, and only one pair can connect at a time, so it isn't a true "two people listening together" setup.
• Wisoqu Open Ear Headphones biggest strength: genuinely ultra-light open-ear design at roughly 13 g, with air conduction that leaves your ear canal open so you hear traffic, teammates and surroundings.
• Wisoqu Open Ear Headphones biggest trade-off: fewer comforts — Bluetooth 5.2 instead of 5.4, a 90 mAh built-in battery with no charging case, and no battery display.
• Who APZXTRK 2-in-1 is for: anyone who wants one purchase to cover sleep, commuting, office calls and light workouts, or who wants a spare pair as backup.
• Who Wisoqu Open Ear Headphones is for: runners, cyclists, climbers and long-wear users who prioritize a nearly weightless fit and situational awareness over extra features.
The APZXTRK 2-in-1 is best understood as a small system rather than a single pair of earbuds. You get two distinct sets in the box: a half in-ear style for everyday listening and movement, and an over-ear style that sits flat enough to be comfortable for side sleepers. Both run on Bluetooth 5.4 with a stated range of up to 33 feet, and both pair under the name "sk35." The charging case carries an LED digital display that shows the battery status of the earbuds and the case itself, which is a genuinely useful touch if you hate guessing whether you're about to run out mid-call.
On the specs, the numbers are solid but not exotic. A single charge gives up to 6 hours of playback, and the case extends total listening to over 30 hours. Quick charging refills in about 1.5 hours over USB-C. The drivers are dynamic with 32 ohm impedance and a 20 Hz – 20,000 Hz range, so expect clear bass-forward stereo sound rather than audiophile detail. Passive noise cancellation means the seal does the blocking, not electronics. There's a built-in mic for calls, touch controls on the buds, and a water-resistant build. Total weight is listed at 1.5 ounces, and the case itself measures about 2.5 x 2.5 x 1.5 inches — small enough to pocket.
Wisoqu Open Ear Headphones: Who It's For
The Wisoqu Open Ear Headphones take the opposite approach: one pair, as light as possible, designed to disappear on your head. The headline figure is the weight — around 13 g (0.46 oz) — built from ABS and skin-friendly silicone. That combination is why the ergonomic shape is described as staying put during high-intensity activity, including when you're wearing glasses or a helmet. If you've ever had earbuds work loose on a climb or a long ride, that's the problem this design is aimed at.
The core idea is air conduction. Instead of sealing into your ear canal, the sound is delivered from outside it, which the product positions as gentler on your ears and less prone to the swelling and pressure that long-wear in-ear buds can cause. The practical payoff is awareness: you keep hearing cars, bikes, dogs and people around you. For road running and city cycling, that's the whole point. Connectivity is Bluetooth 5.2 with support for HSP, A2DP and AVRCP profiles and a stated 10 m transmission range. There's a built-in mic for calls, intuitive on-board controls, and a 90 mAh lithium-ion battery charged by the included USB cable. Sweat resistance is part of the design brief, and the warranty is 90 days.
Who should buy it: runners, hikers, cyclists, climbers, and anyone who wears headphones for hours and finds in-ear buds uncomfortable or unsafe. Who should skip it: people who want deep isolation, a charging case, a battery readout, or the newer Bluetooth generation. There's no case in the box — just the headphones, a USB cable and a manual — so charging is a cable job, and the 90 mAh cell is modest compared with a case-backed system.
• Best for side sleeping → APZXTRK 2-in-1. The flat over-ear pair exists specifically for this; the Wisoqu is an open-ear sport design with no sleep positioning.
• Best for ultra lightweight wear → Wisoqu Open Ear Headphones. At roughly 13 g it's the lighter of the two on the head, and the open fit avoids ear-canal pressure.
• Best for staying aware of traffic → Wisoqu Open Ear Headphones. Air conduction leaves your ear canal open, which is the safer choice for road running and cycling.
• Best for total listening time → APZXTRK 2-in-1. Up to 6 hours per charge with over 30 hours total from the case versus a single 90 mAh built-in battery.
• Best for newer Bluetooth → APZXTRK 2-in-1. Bluetooth 5.4 with a 33 ft range beats Bluetooth 5.2 with a 10 m range on paper.
• Best for convenience extras → APZXTRK 2-in-1. Touch controls, a digital battery display, USB-C quick charge and a pocketable case.
• Best for glasses and helmet wearers → Wisoqu Open Ear Headphones. The fit is explicitly designed to stay stable with glasses or a helmet on.
• Best for two-pair flexibility → APZXTRK 2-in-1. You get a half in-ear set and an over-ear set, though only one pair connects at a time.
In my opinion, most people shopping these two should buy the APZXTRK 2-in-1. Two pairs, a case with a visible battery readout, newer Bluetooth and a much longer total runtime make it the more useful object day to day — sleep, calls, commuting and light training all in one box. I'd only steer you to the Wisoqu Open Ear Headphones if open-ear awareness and a barely-there 13 g fit are the entire reason you're shopping. If you ride or run near traffic, that safety argument is real, and it's worth giving up the case and the battery display for it.
It depends on what you're solving for. If you want one purchase that covers sleep and everyday listening with a charging case, the APZXTRK's two-pair setup is the more versatile buy. If you only need open-ear audio for sport, the Wisoqu is the more focused tool. Check the current price on Amazon before deciding, since value shifts with whatever each is going for.
Can I use both APZXTRK pairs at the same time?
For running, generally yes. The Wisoqu's air conduction design keeps your ear canal open so you can hear your surroundings, and the 13 g build with silicone is made to stay put during high-intensity movement and under a helmet. Sleep earbuds like the APZXTRK's over-ear pair are tuned for comfort lying down, not for traffic awareness.
No. The package is the headphones, a USB cable and an instruction manual. Power comes from the built-in 90 mAh lithium-ion battery, which you recharge over the cable — there's no case and no battery display like the APZXTRK's.
