How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear design that keeps you aware of traffic and training partners while you run, choose 1MORE Fit SE S30; if you need active noise cancellation to shut out a plane cabin or a loud office, choose Coby Active Noise Cancelling. These two earbuds solve opposite problems, and that single difference should decide your purchase before you look at anything else.
• 1MORE Fit SE S30 — biggest strength: an open-ear hook design with a large 14.2mm dynamic driver, up to 30 hours of total playtime, and IPX5 sweat resistance.
• 1MORE Fit SE S30 — biggest trade-off: open-ear buds let ambient sound in by design, so they are the wrong tool if you want to block out noise.
• Coby Active Noise Cancelling — biggest strength: true active noise cancellation with a transparency mode, plus an IPX7 waterproof rating that beats the S30 on water protection.
• Coby Active Noise Cancelling — biggest trade-off: 16 hours of battery life and a 90-day manufacturer warranty, both well behind the 1MORE on paper.
• Who each pick is for: runners, cyclists and gym-goers who want situational awareness → 1MORE Fit SE S30. Commuters, flyers and office workers who want to mute the world → Coby Active Noise Cancelling.
The S30 is built around a hook-style open-ear fit. Instead of sealing a tip into your ear canal, it rests outside it, and the earpiece shape is listed as "Hook." That is the whole personality of this product: you hear your music and you still hear the world. For outdoor runners, that matters more than any spec sheet number, because you are not cutting yourself off from cars, bikes or other people on the path.
Under the hood, 1MORE pairs an enlarged 14.2mm DLC dynamic driver with a bass enhancement algorithm, and the impedance sits at 16 ohm, which is an easy load for a phone to drive. The company also leans on an AI algorithm and four embedded microphones for call clarity. Touch controls handle media and calls, Bluetooth 5.3 keeps the connection current, and the 10-meter range is typical for the class. Battery is the standout: up to 30 hours of listening with the charging case and a 10-hour single charge, with a 2-hour charge time. The 1MORE App lets you adjust EQ modes and button functions.
Who should skip it: if your main use is a noisy flight, a shared office or a train commute, this is not the product for you. There is no active noise cancellation here — the noise control field reads environmental noise cancellation, which is about call clarity, not about silencing a cabin. If you want silence, buy silence.
Coby Active Noise Cancelling: Who It's For
Coby takes the opposite approach. These are in-ear buds with an actual active noise cancellation system rated at up to 30dB of noise canceling, and they offer three modes: active noise canceling, transparency, and normal. That transparency mode is the useful middle ground — you can mute the world on a flight, then flip to transparency to hear a gate announcement without pulling the buds out.
The durability angle is real too. IPX7 is a higher water-protection rating than the S30's IPX5, so heavy sweat and light rain are squarely in scope. Charging runs through a USB-C fast-charge case with a 1-hour charge time, and Bluetooth auto pairing means the buds reconnect as soon as you put them in. Touch controls cover play/pause, skipping and calls. The Coby Smart app adds EQ customization, mode cycling, and GPS-based earbud tracking — genuinely handy if you are the person who loses a bud under a car seat.
The trade-offs are worth stating plainly. Battery life is 16 hours, roughly half the 1MORE's 30, so a heavy user will charge more often. The warranty is 90 days from the manufacturer versus a full year on the 1MORE, which is a notable difference in how long you are covered. Impedance is listed at 140 ohm, far higher than the S30, and Bluetooth is version 5 rather than 5.3 — not dealbreakers, but they tell you this is a simpler, older-generation platform dressed up with modern features like the app and ANC.
Who should buy it: commuters, travelers, open-plan office workers, and anyone whose priority is turning down the volume of the world. Who should skip it: runners who need to hear traffic, and anyone who wants the longest possible time between charges.
Side-by-Side: Which Should You Choose?
• Best for battery life → 1MORE Fit SE S30. 30 hours total and 10 hours per charge versus 16 hours total.
• Best for outdoor training safety → 1MORE Fit SE S30. The open-ear hook design keeps you aware of your surroundings.
• Best for water protection → Coby Active Noise Cancelling. IPX7 outranks the S30's IPX5.
• Best for fast charging → Coby Active Noise Cancelling. A 1-hour charge time against 2 hours on the 1MORE.
• Best for warranty coverage → 1MORE Fit SE S30. One year versus 90 days.
• Best for finding lost earbuds → Coby Active Noise Cancelling. The Coby Smart app includes GPS tracking.
• Best for bass-forward workout sound → 1MORE Fit SE S30. The 14.2mm DLC driver and bass enhancement algorithm are aimed squarely at that.
• Best all-round daily commuter → Coby Active Noise Cancelling. ANC, transparency, USB-C and app control are exactly the commuter checklist.
In my opinion, the right buy depends entirely on whether you want to hear the world or mute it. If you train outdoors, I would buy the 1MORE Fit SE S30: the open-ear hook fit, 30-hour battery, 14.2mm driver and one-year warranty make it the more comfortable long-term companion for running and gym work. If your listening happens on planes, trains and in offices, I would buy the Coby Active Noise Cancelling instead — ANC and transparency are features the S30 simply does not have, and no amount of extra battery makes up for that. I would only hesitate on the Coby if battery life or warranty length is your top priority.
No. It is an open-ear design with environmental noise cancellation, which is used for call clarity rather than blocking surrounding sound. If you want to silence a cabin or an office, the Coby Active Noise Cancelling is the correct pick.
The 1MORE Fit SE S30 lasts longer. It is rated for up to 30 hours with the charging case and 10 hours per charge, while the Coby is rated at 16 hours and charges in about 1 hour.
For sweaty or wet sessions, the Coby has the higher IPX7 rating versus IPX5 on the 1MORE. But for outdoor workouts where you need to hear traffic, the open-ear 1MORE Fit SE S30 is the safer choice.
