They look great.
The product arrived and I tried it myself, the sound quality is very good (compared to the default earphone used for the iPhone 7), now I changed the earpiece, they are very comfortable. It fits perfectly into my ears and doesn't move too much, which also helps with the noise suppression provided by this helmet (which is very good). Coupling is very simple, they are preloaded, so there is no need to use it, magnetic parts are very useful when you are not using them, but you always want them. I would have liked this post to be a bit short, although it fits my personal preferences and not anything, so I can't really blame these headphones! I just need to see how long they last!

Constant sound problems
The sound is very special. I tried 6 different brands of in-ear headphones. When connected to Bluetooth, each note is clear and full. I have tried various classical music, jazz, new age, rock, pop music. The sound quality is very good.

Stick it in your ear - literally!
I am very picky about my headphones, mainly using professional headphones, I am amazed at how good these sounds are. I bought them at the gym so I can leave better gear at home, but it sounds great. The sound quality is as good as those of expensive ones.

Buy at a discounted price!
I am very satisfied with this. They have excellent sound quality and are more bass than my last earphone. They are also more suitable for my ears than my last pair. The sound is great. Great price. Thank you!

I like these more than before.
These are very good earplugs. Sound quality is comparable to headphones and headphones. The controls are easy to navigate and the microphone is great. Excellent value and performance. A combination of treble and treble and bass. Accept my advice, get some, then keep the music guaranteed to burst

My husband likes them. He said that their voices are clear and comfortable.
like! This is the perfect state. And it works very well! I am very happy that they have given different sizes of earplugs because I need those small earbuds; I have had to get used to the ear since I used the iPhone's headphones, but after that, it was very comfortable. And it's also very easy to use. The button can be turned on and off, increasing the volume/next song, reducing the volume/previous song. The sound quality is also excellent because it is in the ear, it is slightly blocked, and the music is more powerful. Bluetooth connection is very good!

Great price
As a student, I know that I want to buy a high quality helmet at a low price. I started to research famous companies such as Beats by Dre and Bose. The Beats by Dre series is priced at $120 and the Bose series is priced at $150. I know that these prices are far beyond my price range and I have to reconsider my strategy. Amazon has a lot of good options, but one of the things I didn't sell is quality. You can find hundreds of Bluetooth headsets under $50, but can they maintain quality? I decided to take this risk and buy superb wireless headphones at this price.

The headphones are very comfortable to wear and the sound quality is very good.
My husband just bought a pair of BOSE wireless devices at the airport for 120.00 euros, which is very interesting, because when I bend over to practice, my phone is always at the top of the gym. I don't know how far you can go before the connection is lost, because it hasn't happened yet. I walked 12 meters and left my bag at the end in the gym and the music was still playing well. My husband said that they are not much different from his quality. The sound, busy time and distance are enough for me. If I haven't bought a Bose pair, it would have been good.
