**I. Introduction**
Since I bought a Bluetooth headset, I've found it to be really convenient, but sometimes I can't carry my own headset with me. That's why I decided to look for a more affordable option. I wasn’t looking for anything too fancy—just something that would work well and fit my budget. So, I ended up going with the Cool Dog M1. Yeah, it was pretty much a casual choice.
When it comes to Bluetooth earphones, it's kind of like crossing a river on a pony—you don’t know how good it is until you try it yourself. Fortunately, this one isn’t too expensive, so even if it doesn’t blow me away, it’s still worth the money.
This is the product:
If you don’t like black, you can go for silver instead.
Before this, I also wrote two other reviews about Bluetooth headsets, which you might want to check out:

**II. Unboxing**
The box is white with a K logo in the center. The image isn’t very clear, though.
On one side of the box, there are barcodes and color options listed.
At the bottom of the box, you’ll find manufacturing information and technical specifications.
Then, just gently push one side of the box open—this is a common packaging style these days. Once opened, you’ll see the slogan “There is always a new game of music.†To be honest, that message didn’t leave a strong impression on me, but I guess it’s just marketing.
Pulling the side a bit further reveals the main earpiece and two additional ear tips.
Everything comes in a full package!
All the accessories are included, and the number of items is standard for most Bluetooth earphones.

**III. Official Description & Personal Experience**
In this section, I’ll share my personal experience using the product.
The image on the front says "Thousands of yuan" style. That’s a bit misleading. I tried it out, and while the sound quality is decent for the price, it definitely falls short of what you’d expect from a higher-end model. The highs, mids, and bass aren’t as refined as they could be.
Lightweight—yes, that’s true.
Small in size—okay, but I’m not fully convinced by the 30% claim.
Battery life—on average, I get around 7 hours of playback. It’s okay, but not quite reaching the 10-hour claim. This may depend on factors like signal strength and volume.
Another promotional image shows a wide range of colors, but I don’t recognize the celebrity group shown. That’s fine—I don’t usually follow entertainment news.
The battery is mentioned here, as well.
These earphones have magnetic closure, so when you close them, they power off automatically. But I’ve accidentally pulled them out of my bag a few times.
My face isn’t on the image, so take a look at the official site.
The technical specs match what was advertised. There’s CVC noise cancellation, but honestly, I didn’t notice much difference. When I made calls, the person on the other end didn’t seem to hear any background noise.
Comparing the ear tips to a baby’s pacifier? Not comfortable at all.
The cable feels stiff and looks durable. Time will tell.
Everything works across different platforms.
The key features are highlighted here.
Everything comes in the box.

**IV. Product Details**
Now, let’s look at the product up close.
A thin transparent film covers the control panel, with detailed specs printed on it.
Suction photos together!
The design of the earphone is not too uncomfortable, even compared to a pacifier. I tried it with my baby’s pacifier, and it was definitely not comfortable.
The control unit has buttons that feel a bit rough.
The back of the control unit houses the microphone, and it works well.
On the side of the control unit is the charging port.
There’s a small hole in the headset—still not sure what it’s for.
When the charging port is open, it looks like this.
The light on the headset glows when turned on.
There’s a bump on the left ear to help distinguish left from right.
Looking at the details now.
After removing the ear pads, the build quality is decent for the price.
Two ear clip adjusters come with the box.
As shown above, after use.
Connected to the phone, as seen.

According to my usual habit, I’ve included two pages of key instructions, and you can skip the unnecessary parts.

**VI. Pros, Cons, and Summary**
After using this headset for a while, here’s my take:
For the price point, I don’t think it’s necessary to compare it to high-end models. However, the sound quality is actually quite good for what it is. The build quality is solid, and the appearance is durable. Compared to some similar-priced headsets, it doesn’t feel cheap or murky. Even though the soundstage isn’t super clear, it’s not chaotic either—it’s great for casual listening.
The sound effects during games are better than when listening to music. The metal sounds and bass are really good.
However, the marketing on the official site is a bit over the top.
Overall, for the price, I think this headset is worth considering. It’s a solid pick for casual users.
