How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a proven everyday Bluetooth headphone with a long talk-time spec and a simple three-button layout, choose iJoy ISO; if you need the newer Bluetooth version, a much longer rated playtime and a hard travel case, choose Wentronic Y05.
• iJoy ISO — biggest strength: an unusually high talk-time rating of 30 hours alongside 26 hours of play time, plus active noise cancellation and a 3.5 mm jack for wired listening.
• iJoy ISO — biggest trade-off: Bluetooth 5.0 and a smaller rated wireless range of 10 metres, so it is the older and less flexible connection of the two.
• Wentronic Y05 — biggest strength: 48 hours of rated playtime, Bluetooth 5.3 and a 15-metre range, which is the more modern wireless setup.
• Wentronic Y05 — biggest trade-off: sound isolation rather than active noise cancellation, and no battery charge-time figure is given.
• Pick iJoy ISO if you take a lot of calls and want an over-ear headphone with ANC and a wired fallback.
• Pick Wentronic Y05 if you want maximum playtime, newer Bluetooth and a foldable design that ships with a hard case.
The iJoy ISO is an over-ear Bluetooth 5.0 headphone built around one clear idea: keep you talking and listening for as long as possible. The spec sheet rates it at 30 hours of talk time and 26 hours of play time from a 2.5-hour charge, with an average battery life listed at 28 hours. That talk-time number is the standout — it is higher than the play-time figure, which tells you the design was tuned for people who spend their day on calls as much as on music.
Around that battery core, iJoy keeps things practical. The earcups fold, so the headphone flattens down for a backpack or a desk drawer, and the controls are three physical buttons covering volume, track skipping, call answering and power. You get a 3.5 mm jack as well as wireless, which matters if you ever want to plug into a laptop, a treadmill or an in-flight entertainment socket without draining the battery. Active noise cancellation is on the spec sheet too, and the drivers are dynamic with a 20 Hz–20,000 Hz range — the standard full-range figure.
Who should buy it: commuters, students and anyone who lives in their headset for work calls and wants a wired option as a backup. The protein leather or memory foam padding and the 11.2-ounce weight point to a headphone you wear in longer stretches rather than one you forget you have on.
Who should skip it: if you want the newest Bluetooth standard or the longest possible listening time between charges, the ISO is not that product. Its 10-metre rated range and Bluetooth 5.0 are the older end of what is on the market, and the matte black finish is the only colour listed — there is no space grey or lighter option here.
The Wentronic Y05 is the more modern of the two on paper. It runs Bluetooth 5.3 with a rated range of up to 15 metres, and the spec sheet claims ultra-stable, low-latency performance with anti-interference technology — the kind of thing that matters in a crowded flat or a busy office where a lot of devices are competing for the same airwaves. For movies and gaming, low latency is the difference between lip-sync and a noticeable lag, so that is a genuine functional advantage rather than a marketing line.
The headline number is battery: 48 hours of rated playtime. That is close to double the iJoy's play-time figure, and it is the single strongest reason to pick the Y05. Wentronic does not list a charge time, so I would treat the 48 hours as the claim to plan around and assume a full top-up takes a normal overnight session.
Comfort gets real attention in the design notes. The Y05 uses memory-protein ear cushions on an adjustable headband, with rotating earcups that are described as conforming to head shape and a padded band that is specifically called out as accommodating glasses wearers. The frame is described as lightweight — the listed weight is 0.3 kg — and the materials are breathable to limit heat build-up, which is the usual complaint with over-ear headphones in summer. The build folds via a collapsible hinge and ships with a hard case, so it travels better than a bare folding pair.
Who should buy it: travellers, long-haul listeners, gamers watching for latency, and glasses wearers who find most over-ears press on the arms of their frames. The space grey finish and minimalist styling make it easy to wear outside the house.
Side-by-Side: Which Should You Choose?
• Best battery life → Wentronic Y05. 48 hours of rated playtime against the iJoy's 26 hours of play time.
• Best for phone calls → iJoy ISO. A 30-hour talk-time rating is the specific figure iJoy leads with, and it is the higher of the two call-focused specs here.
• Best wireless connection → Wentronic Y05. Bluetooth 5.3 with a 15-metre rated range versus Bluetooth 5.0 at 10 metres.
• Best for noisy environments → iJoy ISO. Active noise cancellation is listed, where the Y05 relies on passive sound isolation.
• Best for travel → Wentronic Y05. Foldable hinges plus a hard case, with rotating earcups and a padded band designed around glasses wearers.
• Best for charging predictability → iJoy ISO. A stated 2.5-hour charge time; Wentronic gives no charge-time figure.
• Best for plugging in → a tie. Both list a 3.5 mm jack, so either works wired.
• Best for a lighter-feeling fit → Wentronic Y05 on the listed 0.3 kg weight, versus the iJoy's 11.2 ounces.
In my opinion, the Wentronic Y05 is the better buy for most people in 2026. Bluetooth 5.3, a 15-metre range, 48 hours of rated playtime, a hard case and comfort features aimed at glasses wearers add up to a more current, more travel-friendly headphone — and the low-latency claim is the one that actually changes day-to-day use for video and gaming.
I would only reach for the iJoy ISO if calls are the main job and you want active noise cancellation plus a known 2.5-hour charge time. That is a real, specific use case, not a consolation prize. But as an all-rounder, the Y05 wins on the specs that matter most.
Wentronic Y05, on the numbers given. It is rated at 48 hours of playtime, while the iJoy ISO is rated at 26 hours of play time and 30 hours of talk time.
The iJoy ISO lists active noise cancellation; the Wentronic Y05 lists sound isolation, which is passive blocking from the ear cushions rather than electronic cancellation.
Yes. Both the iJoy ISO and the Wentronic Y05 list a 3.5 mm jack alongside Bluetooth, so you can plug in when you want to save battery or your device has no wireless.
The Wentronic Y05 is the more comfortable bet on paper, with memory-protein cushions, rotating earcups, a padded headband described as accommodating glasses, and a hard case for travel. Check the current price on Amazon before deciding, since value shifts over time.
