How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless, open-ear running headphone with situational awareness and a charging case, choose Audiovance OpenComfy 301; if you need a simple wired 3.5mm in-ear set with a microphone for older iPhones, tablets and computers, choose Mutsrd 2.
• Audiovance OpenComfy 301 — biggest strength: a true open-ear, ear-hook design built around runners, with ambient awareness, Bluetooth 5.3, touch controls and a charging case. Biggest trade-off: it's a single-purpose sports headphone — no wired fallback, and the open-ear fit means less passive noise blocking by design.
• Mutsrd 2 — biggest strength: plug-and-play wired reliability across a long list of 3.5mm devices, with a built-in mic and remote on the cord, sold as a two-pack. Biggest trade-off: it's a wired in-ear set with a 3.5mm plug, so it won't work with phones that dropped the headphone jack, and there's no battery, case or wireless range to speak of.
• Who the Audiovance is for: runners, cyclists, gym-goers and anyone who wants music without sealing off the world.
• Who the Mutsrd 2 is for: anyone with a 3.5mm jack who wants cheap, no-fuss wired earbuds with a mic for calls and everyday listening.
The OpenComfy 301 (model CF301) is designed with one job in mind: staying on your head and out of your ear canal while you move. It's an open-ear, ear-hook headphone, which means the driver sits outside your ear rather than plugging it. Audiovance pairs that with soft silicone cushions and ergonomic hooks that the spec sheet says are meant to fit a range of ear sizes — including over glasses or under a helmet. For runners, that's the whole point: nothing pressing into your ear for an hour, and your ears stay open to traffic, other people and whatever's happening around you.
Where it pulls ahead for active use is the wireless package: Bluetooth 5.3 with a rated 33ft range, four ENC microphones for calls, touch controls for volume, playback and calls, IPX5 water resistance, and a compact charging case. Battery is quoted at 10 hours per charge and up to 30 hours with the case, with a 1.5-hour full charge and a 10-minute quick charge giving 75 minutes of playback. Note that the product information lists average battery life at 7.5 hours, so treat the 10-hour figure as the best-case claim and 7.5 as a more conservative expectation. It ships with a 12-month warranty.
Buy it if you run, cycle or train outdoors and want your ears free. Skip it if you want maximum isolation on a plane, or if you need a wired connection for a device without Bluetooth.
Mutsrd 2: Who It's For
The Mutsrd 2 is the opposite philosophy entirely. It's a two-pack of wired in-ear earbuds with a 3.5mm AUX plug, a built-in microphone and an inline remote. There's no battery, no pairing, no case — you plug them in and they work. For anyone who has ever stood on a platform waiting for earbuds to connect, that simplicity has real appeal.
Compatibility is the headline. Mutsrd lists support for a long run of older Apple hardware — iPhone 6s Plus, 6s, 6 Plus, 6, 5s, 5c, 5, SE, several iPad Pro, Air and mini generations, iPad 4, iPod Touch 5 and iPod nano 7 — plus tablets, PCs and other 3.5mm audio devices, and it states iOS and Android support. The wired, in-ear, plastic build is light, and Mutsrd describes soft cables and an ear shape meant to adapt for long listening sessions. Sound is described as bass-forward with high-quality drivers; the inline remote handles volume, play/pause and answering or ending calls with a press.
The honest trade-offs: this is a wired set, so it's tethered to your device, and there's no water-resistance rating, no wireless range and no battery figures given. It also won't fit phones that dropped the 3.5mm jack without an adapter. And because it's in-ear, it blocks more outside sound — good on a commute, less good if you want to hear traffic.
Buy it if you have a 3.5mm device, want a spare pair, and value plug-and-play simplicity. Skip it if your phone is jackless, or you want wireless freedom for running.
• Best for running and outdoor training → Audiovance OpenComfy 301. Open-ear hooks, IPX5, ambient awareness.
• Best for hands-free calls on the move → Audiovance OpenComfy 301. Four ENC mics and touch controls beat a single inline remote for active use.
• Best for battery-free, always-works listening → Mutsrd 2. No charging, no pairing, no dead earbuds.
• Best for older iPhones, iPads, iPods and computers → Mutsrd 2. The 3.5mm plug covers a long list of legacy devices.
• Best for wearing with glasses or a helmet → Audiovance OpenComfy 301. The ear-hook design is explicitly built for that.
• Best for blocking out a noisy commute → Mutsrd 2. In-ear fit seals more sound than any open-ear design.
• Best for a spare pair you can leave in a bag → Mutsrd 2. It's a two-pack and needs no power.
• Best for a single do-everything active headphone → Audiovance OpenComfy 301. Bluetooth 5.3, case, quick charge and controls in one unit.
In my opinion, the Audiovance OpenComfy 301 is the one I'd buy — provided you're buying for movement. The open-ear hook design, IPX5 rating, Bluetooth 5.3, four-mic calling and charging case make it a genuinely purpose-built running headphone, and the 10-minute quick charge is the kind of detail that matters when you're heading out the door. The Mutsrd 2 is a fine, honest wired set, but it's a different tool for a different job. If your phone still has a 3.5mm jack and you just want cheap, dependable wired earbuds, the Mutsrd 2 does that well. For everything active, I'd go Audiovance.
