The first time I tried out Zhang Aunt's drying, it was quite ordinary. She had a small heart, and even though the sun wasn't exactly high-end, it definitely appealed to the average person. She put up three fingers and swore: "I use my real feelings and emotions, even though I'm not a professional, I’ll try to be as objective as possible. If I break this oath, may I be cursed."
Let’s talk about why I decided to start this review. It’s often said that a woman’s wardrobe will always have one less piece of clothing. That next piece you see in the mall might catch your eye, but with weight gain and changes in body shape, it’s better to focus on losing weight rather than constantly searching for ways to look thinner. I’ve decided to keep my legs moving and run every night.
I believe that all the chubby girls who listen to this song on cable TV have felt this kind of jealousy. They try to hold their arms together, only to find the headphone cable tightening around their necks. The cable gets shorter and shorter, and the weight of the clip becomes unbearable. I've sacrificed two premium headphones in the past, but despite all this, I believe many people will nod and exclaim, “Me too!â€
Well, the Bluetooth headset came into play. Before I read about the M1 model, I had already explored Jabra, Plantronics, Dafa, and Beats. These were all great products! But for someone like me who is still learning about audio equipment, a capitalized “valuable†seems to loom over my head. Even if I manage to buy one, within a month or two, I’d be broke. So, I started paying attention to budget-friendly headphones. Just like before when I fancied Jabra for its magnetic switches, I found the M1 model, Edifier W280BT, and LeTV Bluetooth sports headphones appealing. I still recognize these brands, even though some audiophiles might roll their eyes when I mention them. What can I do? I’m a beginner, please bear with me. Anyway, I only care about the sound quality. The problem was the price. Starting from 149 to 69 yuan, it felt a bit steep. So, I gave up on LeTV because its sound effects were subpar, like it was far away on the horizon.
Finally, I settled on the Cool Dog M1. At least, it had an app with decent music options. Also, the design looked good with magnetic switches, which met my initial requirements. As for the in-ear sound leakage issue, after learning about Jabra, I figured that if I went with an in-ear style, this problem was unavoidable. Besides, Plantronics' BackBeat Fit doesn’t have this issue, but it’s a bit too sporty and odd-looking. Despite people saying it breaks easily after a month or two, the price made it worth considering. I thought, better something that lasts a bit longer than nothing at all. I balanced the features and face value, and ordered it from Jingdong for 99 yuan. I sat and waited...
Jingdong's delivery speed is amazing. By the morning and afternoon, it was ready to be unboxed. Women always enjoy the thrill of unboxing, no matter what the item or price. The outer packaging was satisfying—lightweight and sleek.
Opening the carton, it was functional but not overly精致. The Cool Dog K logo was on the outside of the box, along with a barcode on the side. This barcode, according to my tests, was just Jingdong's shipping code and not for security purposes. I asked customer service about it, but they said they couldn’t temporarily check the security code. I was disappointed. Even though the price was reasonable, as a well-known music platform, you’d expect better attention to detail.
On the back of the box, the product name was listed: 13g aluminum-magnesium alloy shell, magnetic switch, dual battery with 120mAh, 10-hour battery life.
The packaging used a drawer-style opening method. After removing the upper and lower seals, you could push it out from either side. The diagram showed the box divided into two parts: the upper part contained the earphones and two sets of earplugs, while the lower part could be directly taken out. It was printed with “Music always has new ways to play.â€
Removing the headset and the tray, everything inside was visible. There was a data cable, three sets of ear tips (including the loops), a pair of three-hole clips, and a user manual. That was it—three sets of ear tips (large, medium, small), three sets of earplugs (excluding the loop), and earflaps for everyone to test. I used the smallest earbuds with medium earflaps. When not exercising, you can use the earflaps. They’re easier to lose, so be cautious. Also, they’re a bit stable, at least preventing my head from shaking. I haven’t tested it while running yet.
The headset automatically turns on when separated, with a white light above the line flashing. Bluetooth pairing has voice prompts: “Hello Kugo, Bluetooth pairing, Bluetooth connected.†For subsequent use, if the mobile phone Bluetooth isn’t turned off, pairing and connecting happens almost instantly. There’s a prompt tone in the headset, “Bluetooth pairing, Bluetooth connected.â€
My current usage time is less than half a month. The connection is seamless—Bluetooth pairing is quick, and the remote control has a white light that flashes for pairing. The connection is also fast, with a prompt tone in the headset. If you’re listening to content before, you don’t need to reopen the phone to play again; pressing the middle button on the remote control will continue playback.
For app testing, I used several commonly available music apps on my phone: Shrimp, QQ Music, and NetEase Cloud. Personally, I prefer Jay Chou’s music, so I didn’t delete my account even after running out of money. These apps were mostly compatible. The middle button plays and pauses, while long-pressing the volume buttons switches tracks. Initially, pressing the middle button to pause and then trying to resume playback caused issues. I experienced this problem four or five times, but I’m not sure if it was a minor bug. After a few uses, it seemed resolved. Other than that, the Cool Dog app had sound effects specifically for M1, but personally, I found it lacking. Listening to NetEase Cloud was better, with most songs having a standard 128kbps sound quality, which wasn’t bad. I’m curious about how different apps affect the sound quality of the headphones. Everyone should try different apps to compare.
Sound quality-wise, if you're chasing high fidelity, Bluetooth headphones will always fall short compared to wired ones. While I haven’t tried other high-end Bluetooth headphones, I personally feel that Bluetooth always loses some sound quality during transmission. Regarding this headset, I found it satisfactory, especially the in-ear style, which suited my preferences.
For calls, I tested it while running. My husband called me, and he said the voice was slightly softer than usual, but the headset was clearer than normal phone calls. Outside, there was no noticeable noise, even when I ran in windy conditions with passing cars. The headset’s middle button is easy to press, and there’s a prompt tone indicating who’s calling, which is convenient.
After connecting the headset to Bluetooth, it showed 100% full power. From 4 p.m. in the afternoon, it lasted until 40% the next noon. Charging it fully takes about 1.5 hours (when the battery is below 20%, there’s a voice prompt to charge). Full power allows for basic usage, including calls, WeChat voice, and listening to songs, lasting 7-8 hours. This is slightly less than the official claim of 10 hours, but it’s still useful for daily use. I charge it every two days when I commute and listen to music at night. Sometimes the battery display on the phone isn’t accurate, showing a decrement of 20 units without real-time updates. I’m not sure if it’s a problem with the headset or my phone. Overall, it works fine.
When it comes to sports, I found the wind noise to be a bit loud. It felt like taking them off at times, even when the wind wasn’t strong. The stethoscope effect is common with in-ear headphones, and it’s hard to avoid. You can hear every step and the wind mixed with background music—it’s overwhelming. I tried different earplugs, starting with the smallest size. Comfort varies from person to person, so it’s subjective.
During sports, the Bluetooth stability was okay when running normally, but arm movements or leg stretches caused brief disconnections. It was short-lived but noticeable. I’m not sure why this happened—perhaps my arm blocked the signal?
In conclusion, the advantages include fast Bluetooth connection, magnetic attraction for convenience, and quick pairing after opening and closing. Voice prompts are smart and practical. The battery life is decent, lasting 7-8 hours, meeting wireless demands for two days. The disadvantages include the common in-ear stethoscope effect, discomfort after wearing for over an hour, non-real-time battery display, and unstable Bluetooth range.
Overall, if you prioritize sound quality, go for wired headphones—they’re superior. Bluetooth is more about convenience. If you’re into sports, consider the Plantronics BackBeat Fit style. For casual users who just want to eliminate the hassle of wires, this headset is a good choice at a reasonable price. It’s surprising for its cost. However, if you plan to wear it while exercising, I’d recommend looking elsewhere. In short, buy based on your needs, and the price should reflect those needs.
PS: This is my first unboxing review, taking half a month to prepare. I took photos (real shots), tested, and edited. It was fun, and I hope to share my experience. I hope it helps others who might refer to it.虽然是 not professional, I did it with sincerity.
