Hi Team,

I’ve been using bone conduction headphones and have a few ideas to make them even better:

1. Sauna-Proof Design**
Let’s make them survive **190°F saunas** with heat-resistant materials like titanium. IP69 is great, but steam and heat can still mess with performance.

2. Bluetooth Booster**
Weak Bluetooth in saunas/pools is frustrating. A small **clip-on booster** could keep the connection strong for live streaming without needing pre-downloaded music.

3. AI-Powered Sound Enhancement**
Add an **AI chip** to optimize sound quality in real-time. It could:
- Reduce vibrations for comfort.
- Boost bass and clarity dynamically based on the environment (e.g., richer bass for music, clearer highs for calls).
- Enable an **immersive surround sound mode** for a concert-like experience.

4. Fix Charging Issues
The magnets on my charging cable fell out—now I’m stuck. Let’s switch to a **snap-on dock** or durable USB-C port that can handle heat, sweat, and daily wear.

These upgrades would make the headphones unstoppable for extreme environments and everyday use. What do you think?

The device’s charging failure—caused by detached magnets—creates a dissonance between your brand’s promise of quality and the current experience. This isn’t a plea; it’s an observation. Every unresolved flaw lingers in the subconscious of customer trust, quietly eroding what marketing strives to build.

A replacement isn’t charity—it’s strategic. It transforms a friction point into a loyalty loop: a silent testament to your commitment to seamless excellence. The alternative? Letting a $0.02 magnet dictate the narrative. I suspect we both know which path aligns with the legacy you’re cultivating.

Easy to download songs onto headset. headset is light, comfortable and adjustable. Sound is good on MP3 mode when swimming. Charge lasts long. MP3 mode has a shuffle feature which is great. Can also be used to answer calls but I have not tried that yet.

Overall satisfied with the product, the quality of the build and usability. Durability of the product is yet to be proved.
The underwater sound quality during pool swim sessions are good as expected, it simply works.
The user's manual can improve by providing examples of what apps to use to download podcasts onto the device. It is not that difficult, but instructions could have saved me 30-60 mins.

i bought the NANK Runner Driver2 Pro off amazon. the battery life is better than i expected. the sound quality is amazing to me. i'd rather use these than my samsung ear buds. they sound great when out of the water but in the water these are awesome. my ebook comes in so clearly. it's also nice to have these on in the shower and not subject my apartment neighbors to my music or podcasts early in the morning. i don't use the ear plugs. don't feel the need for them. this product is very comfortable. the way they are charged is weird but understandable considering the waterproofing.
i ended up buying a second one for home and outdoors. my family told me i came in very clearly when i called them while using these.
