How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a slim, weather-ready way to carry small essentials on your bike frame, choose MATTISAM Tube Bike Bag; if you need open-ear audio that keeps you aware of traffic while you run, ride or hike, choose Filenor Bone Conduction Headphones. These are two completely different products that happen to share a cycling audience, so the right answer depends entirely on what problem you're trying to solve on your next ride.
• MATTISAM Tube Bike Bag — biggest strength: a 1L top-tube pouch in water-resistant polyester with sealed zippers, a shielded lid, reflective strips and a reserved headphone port for running audio cables out of the bag.
• MATTISAM Tube Bike Bag — biggest trade-off: 1L is a small, focused capacity. It's for keys, phone, snacks and tools, not for a full touring load, and the water resistance is aimed at light rain rather than submersion.
• Filenor Bone Conduction Headphones — biggest strength: an open-ear bone conduction design with a 29g flexible titanium frame, IP55 waterproofing, 8 hours of playtime and Type-C fast charging with a 10-minute quick charge.
• Filenor Bone Conduction Headphones — biggest trade-off: bone conduction trades deep bass isolation for situational awareness, and the open-ear fit means you hear wind and traffic along with your music.
• Who each pick is for: the MATTISAM bag suits commuters and road riders who want tidy, secure storage on the frame; the Filenor headphones suit runners, cyclists and hikers who want music without blocking out the world around them.
The MATTISAM Tube Bike Bag is built around one clear idea: put a small amount of gear exactly where you can reach it without stopping. It's a 1L top-tube bag made from water-resistant polyester with sealed zippers, and the lid adds an extra layer of water shielding so your phone, wallet or snacks stay dry in light rain. That combination matters more than it sounds. A top-tube bag lives in the worst possible spot for weather — right out front, fully exposed — so sealed zippers and a covering lid are the features I'd actually look for, and this bag has both.
Then there's the detail that ties these two products together: a reserved headphone port. You can run an audio cable out of the bag without opening it, which means your phone stays sealed and dry while you listen. If you already ride with wired audio, that's a thoughtful bit of design rather than an afterthought. It's a 1L bag with a side mesh pocket for quick-access small items, one included component (the bag itself) and a 1-year manufacturer warranty.
Who should buy it: commuters, casual road riders and anyone who wants a tidy, low-profile pouch for keys, phone, cards and a snack. Who should skip it: bikepackers or touring riders who need multi-litre capacity, or anyone expecting heavy-duty waterproofing for sustained downpours.
Filenor Bone Conduction Headphones: Who It's For
The Filenor Bone Conduction Headphones are for the rider or runner who refuses to choose between music and awareness. The open-ear design transmits sound vibrations through your cheekbones rather than firing audio into a sealed ear canal, so your ears stay open to cars, other people and hazards around you. Filenor says the fully enclosed cavity reduces sound leakage by up to 50%, which addresses the usual complaint about bone conduction — that everyone nearby hears your playlist too.
Comfort is where the spec sheet gets interesting. The frame is flexible titanium memory material with ABS and silicone contact points, and the whole thing weighs just 29g. A wraparound titanium frame that's been designed to withstand stretching and bending without deforming is exactly what you want from something that lives in a gym bag or helmet strap. The hook-shaped earpieces sit over the ear rather than inside it, and the 16mm bone conduction driver handles the audio. Impedance is rated at 120 ohm with a 20 KHz frequency response and 38 dB sensitivity — figures that tell you this is a purpose-built bone conduction driver, not a repurposed in-ear speaker.
Battery and connectivity are straightforward: up to 8 hours of music or calls, Bluetooth 5.0 with roughly a 33-foot range, and Type-C fast charging that includes a 10-minute quick charge for about 1.5 hours of playback. That quick-charge feature is the one I'd value most — it turns a forgotten charge into a usable workout. There's a built-in mic with environmental noise cancellation for hands-free calls, button controls on the frame, and an IP55 waterproof rating that covers sweat, rain and splashes during running, hiking, cycling and gym sessions.
In the box you get the headphones, a Type-C charging cable, two sponge earplugs and a manual, with a 1-year warranty and support the brand says responds within 12 hours. Who should buy it: runners, cyclists and hikers who want open-ear audio and maximum awareness. Who should skip it: anyone who wants deep, isolating bass in a loud environment — that's simply not what bone conduction does.
• Best for carrying gear on the bike → MATTISAM Tube Bike Bag. 1L of water-resistant, sealed-zip storage with a lid for extra shielding.
• Best for listening on the move → Filenor Bone Conduction Headphones. Open-ear bone conduction with 8 hours of playtime and quick charging.
• Best for night riding safety → MATTISAM Tube Bike Bag for its reflective strips, or the Filenor headphones if staying aware of traffic is the priority.
• Best for sweat, rain and hard workouts → Filenor Bone Conduction Headphones with an IP55 rating and a 29g titanium frame built to flex without deforming.
• Best for phone protection in light rain → MATTISAM Tube Bike Bag, thanks to sealed zippers and the covering lid.
• Best for hands-free calls → Filenor Bone Conduction Headphones with a built-in mic and environmental noise cancellation.
• Best for wired audio on the bike → MATTISAM Tube Bike Bag, which has a reserved headphone port so a cable can exit without opening the bag.
• Best for fitting almost any bike → MATTISAM Tube Bike Bag, which includes three detachable straps in different lengths.
In my opinion, if you're buying for the bike itself, get the MATTISAM Tube Bike Bag. A 1L water-resistant top-tube pouch with sealed zippers, a shielding lid, reflective strips and three mounting straps solves a real, everyday problem — carrying your phone and keys securely without a backpack — and the headphone port is a genuinely smart touch for riders who listen on the go. I'd pick the Filenor Bone Conduction Headphones instead if your actual goal is audio for running, hiking or gym work, because 8 hours of playtime, IP55 waterproofing, a 29g titanium frame and open-ear awareness are hard to argue with for that use case. If you can only choose one, buy the product that matches the problem you have today.
It's made from water-resistant fabric with sealed zippers and a lid that adds extra shielding, so it's designed to keep contents dry in light rain. It isn't intended for full submersion or sustained heavy downpours.
Yes — that's one of their main use cases. The open-ear design keeps you aware of traffic and surroundings while you ride, and the IP55 rating handles sweat and rain, with a 29g frame that stays put during activity.
No, and that's the point. Bone conduction leaves your ear canal open so you hear your music through vibration while still hearing cars, people and hazards around you.
Buy the MATTISAM Tube Bike Bag if you mainly need to carry small items on your frame, or the Filenor Bone Conduction Headphones if you mainly need open-ear audio for sport. Check the current price on Amazon for whichever fits your riding routine.
