How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life in an over-ear headphone with a modern Bluetooth spec and app-based sound tuning, choose TOZO HA1; if you want a simple, lightweight foldable with a wired 3.5 mm fallback and physical button control, choose iJoy ISO.
• iJoy ISO — biggest strength: A very long spec'd talk time (up to 30 hours) and play time (up to 26 hours) with a quick 2.5-hour charge, plus a 3.5 mm jack for wired listening.
• iJoy ISO — biggest trade-off: Older Bluetooth 5.0, a shorter 10 m wireless range, and it lacks the app-based EQ customization the TOZO offers.
• TOZO HA1 — biggest strength: A huge 70-hour battery rating, Bluetooth 5.4, a 20 m range, 32 EQ presets via the TOZO app, and a 78 ms low-latency game mode.
• TOZO HA1 — biggest trade-off: Heavier than the iJoy at 235 g, and the app/EQ feature set is more than a casual listener needs.
• Buy the iJoy ISO if you want a no-fuss, lightweight commuter headphone with a wired backup and long call time.
• Buy the TOZO HA1 if you want maximum battery, gaming-grade low latency, and customizable sound.
The iJoy ISO is built around the fundamentals. You get Bluetooth 5.0 wireless, a foldable over-ear frame in matte black, and three smart buttons that handle volume, track skipping, call answering, and power. No app, no menus to learn. The battery story is the headline: iJoy rates it at up to 30 hours of talk time and 26 hours of play time, with a full charge taking about 2.5 hours. The product info also lists an average battery life of 28 hours, so expect a long week of commuting between charges.
The iJoy ISO is for the person who wants a simple daily driver: toss it in a backpack, fold it flat, take calls on the go, and plug in the 3.5 mm cable when the battery runs low or when you're on a flight with a seatback jack. Skip it if you want customizable EQ, a lower-latency gaming mode, or the newest Bluetooth version — those aren't part of this design.
TOZO HA1: Who It's For
The TOZO HA1 is the more feature-dense of the two. Its 70-hour battery rating is the standout, and the 2-hour charge time is quick for that capacity. Bluetooth 5.4 is the newer standard here, and the 20-meter range doubles the iJoy's. If you want to leave the charger at home for a week-long trip, this is the one that makes that realistic.
Audio is handled by a 40 mm dynamic driver with 32-ohm impedance and 88 dB sensitivity, and the frequency range runs 20 Hz–20,000 Hz. The real differentiator is the software: the TOZO app unlocks 32 preset EQ modes, so you can nudge the sound toward rock, classical, or electronic without buying anything else. There's also a 78 ms low-latency mode aimed at gaming, where footsteps and explosions need to land in sync with the screen.
For calls, the HA1 uses ENC ambient noise cancellation to filter background sound and isolate your voice — handy on a subway or in a busy office. The design is ergonomic and foldable, with 90-degree rotating earcups, an adjustable headband, and breathable sponge earpads. TOZO notes the headset fits head circumferences of 54–63 cm. At 235 g it's heavier than the iJoy, but the rotation and padding are there to spread that weight.
Pick the TOZO HA1 if you want the longest runtime, the newest Bluetooth, app-tuned sound, and a gaming mode. Skip it if you prefer a set-and-forget headphone with no app and a lighter frame.
Side-by-Side: Which Should You Choose?
• Best for call time → iJoy ISO. It's rated up to 30 hours of talk time, which is unusually high for a headphone in this class.
• Best for the newest wireless standard → TOZO HA1. Bluetooth 5.4 and a 20 m range beat Bluetooth 5.0 and 10 m.
• Best for wired listening → iJoy ISO. Both list a 3.5 mm jack, but the iJoy's design and lighter 11.2 oz frame make it the easier grab-and-go wired option.
• Best for gaming → TOZO HA1. The 78 ms low-latency mode is built for it; the iJoy has no equivalent.
• Best for customizable sound → TOZO HA1. The 32 EQ presets via the TOZO app are unique to this pick.
• Best for simple operation → iJoy ISO. Three physical buttons and no app required.
• Best for long-wear comfort (on paper) → iJoy ISO. Lighter weight plus memory foam pads favor it for all-day wear.
In my opinion, the TOZO HA1 is the stronger buy for most people. The 70-hour battery rating, Bluetooth 5.4, 32 EQ modes, and 78 ms gaming mode cover more use cases, and the app means the headphone can grow with your taste. The iJoy ISO still makes sense if you want something lighter, simpler, and wired-friendly with exceptional talk time — but as an all-rounder for commuting, travel, and gaming, I'd go with the TOZO HA1. Check the current price on Amazon before you commit, since both sit in a budget-friendly space.
Yes, clearly. TOZO rates the HA1 at 70 hours of playtime, while iJoy rates the ISO at 26 hours of play time and up to 30 hours of talk time. The HA1's 2-hour charge also beats the iJoy's 2.5-hour charge.
The data sheet lists Active Noise Cancellation as a noise-control feature, and the TOZO HA1 lists the same. The TOZO also adds ENC ambient noise cancellation specifically for calls, which the iJoy sheet doesn't mention.
The TOZO HA1. It supports a 78 ms low-latency game mode and Bluetooth 5.4, which is designed to keep audio and video in sync. The iJoy ISO has no low-latency mode listed.
On paper, the iJoy ISO is lighter at 11.2 oz versus 235 g for the TOZO HA1, and it uses memory foam pads. The TOZO counters with 90-degree rotating earcups, an adjustable headband, and breathable sponge pads for head circumferences of 54–63 cm.
