If you are a sporty person and you don't want to deprive yourself of your favorite music when you train, you will surely have tried and bought different earphones. The choice essentially falls on 3 distinct models: the classic in ear, the over ear and the open ear (which today I will talk to you specifically with the BM-CT3 Pro).
Topics of this article:

What are the differences between these 3 models? Well, if you are an expert I don't have to explain them to you, but if you are a "beginner" I can tell you that the first 2 are the best headphones for listening quality while the third are the best and most comfortable. The "in ear" are the classic small earphones that are inserted into the auricle and isolate you almost completely from the outside (with or without active noise reduction). The "over ear" are those with large pavilions that cover the entire ear (like those for gamers or DJs) and they also isolate you from the outside world, these again compared to the in ear. It is obvious that they also bring the best audio quality but the problem is precisely the isolation from the outside world. In fact, imagine a runner who runs on a road and in this way does not hear a car that is hitting him.. or in the gym where you often exchange a few words with friends having to continually take them off and put them back on. Well, open ear headphones solve this problem by leaving the auricle free and still playing music with a good quality level. Some time ago I tried the CT4 by BlitzRock and I found them to be a product with a very high quality/price ratio. Today I'm talking to you about them BlitzRock BM-CT3 Pro the flagship of the well-known Chinese brand.

HOW DO THEY WORK
There are mainly two technologies used in open-ear headphones:
- Bone conduction: In this case, the sound vibrations are transmitted through the cheekbones, directly reaching the inner ear. This bypasses the eardrum and allows the sound to be perceived without blocking the ear canal.
- Short-distance aerial conduction: This technology, used for example by Bose, involves reproducing sound at a short distance from the ear canal, creating a rich and deep audio experience without obstructing the ear.
What are the advantages of open-ear headphones?
- Environmental awareness: With your ears free, you can stay aware of what's going on around you, such as traffic or conversations.
- Comfort: Thanks to the open design, these headphones are generally more comfortable to wear for long periods.
- Security: They allow you to stay alert to external dangers, making them ideal for activities such as running or cycling.
- Sound quality: While they don't offer the same immersion as traditional headphones, many open-ear headphones offer surprisingly good sound quality.
When to choose open-ear headphones?
- Outdoor Activities: They are perfect for those who love playing sports or simply walking outdoors, ensuring safety and comfort.
- Hands-free calls: They allow you to clearly hear the voice of your interlocutor and be heard clearly.
- Prolonged use: Thanks to their comfort and less pressure on the ear, they are ideal for those who wear them for many hours a day.
What are the disadvantages of open-ear headphones?
- Limited sound insulation: They are not suitable for noisy environments, as they do not offer complete sound insulation.
- Bass quality: Generally, the bass output is lower than traditional headphones.

APPLICATIONS
The possibility of connecting our devices is truly exceptional. BM-CT3 Pro to the BlitzRock application from which you can manage the settings. Inside the package you will find a card with the QR code that will send you to the application to download through your store (google play or app store). You can also search for it manually in the store, you will have to search for Blitzrock. Once downloaded and installed, open it by giving the usual permissions (location, BT, nearby object detection, etc.). At this point you will find yourself in the home where you will find the "add device" button, click on it and the CT3 Pro headphones will be automatically detected, confirm by clicking on the headphones. Now you will be in the device list screen and at the top you will find the headphones just detected.




Now we can go into the details of our headphones and change the settings.
In the first screen we will find an overview of the headphones with the charge level of each earphone and the equalization curve set (by default everything will be flat).

By clicking on “choose other effects” we will enter the “recording studio” screen, here we can enter the equalizer customization screen. Here we will have the possibility to choose 3 preset curves (sporty, relaxing and warm) or modify it manually, up to 7 bands, by going to “custom eq”. If we then want to return to the “flat” curve we can click on “reset”





Returning to the home screen, at the top right we will have the gear icon of the general settings. Entering here we will find 4 menus: factory reset, firmware version, key settings and rename device. The firmware version menu, to update it, will be usable only after registering with an account, which you can do from the home screen at the bottom right (mine). Very interesting instead is the key settings menu where you can modify the actions corresponding to the touches of the earphones as you like.


On the home screen, as I said above, you will have the possibility to register by creating an account. In the “my” TAB you will then have other menus to browse. The language set for the voice feedback is English, there is currently no Italian language.

HOW DO BM-CT3 Pro FEEL?
I must admit that I never thought I would find open earphones that, at this price (which I will tell you about later) could deliver this sound quality. While for the mid-highs you can also find other quality products, as far as the low frequencies are concerned they surprised me. It is well known that open bone conduction devices cannot deliver very deep low frequencies but these CT3 Pro they really do a little miracle thanks to their 12x12mm drivers that guarantee us a truly significant sound on the lows. Let's be clear, we are not at the level of "in ear" products of the same price, it would be absurd to think so, but I can assure you that even the music that "pushes" on the lows you can listen to with good satisfaction. As a lover of dance music I can absolutely say that these open earphones are the best I have tried for this type of music.
Good mid-highs that feel really present and crystal clear, as I must say excellent audio quality in calls, both of the caller and the recipient. During the call in fact 4 microphones and AI will intervene to improve listening and suppress any background noise.
FINAL CONSIDERATIONS
First of all I would like to remind you what the best use of open headphones is, namely sports. The specific feature of these headphones allows us to listen to music and hear the noise around us. For example, it is recommended to use them when running/walking on the street to always have an idea of the possible dangers that surround us. In these cases, it is a terrible idea to use in-ear headphones that would isolate us from the entire outside world, dangerously putting our safety at risk. They are also perfect for use in the gym where I often see people taking their in-ear/over-ear headphones off and on 30 times during a workout because it is mandatory to do so to interact with other people. Absolutely recommended also for those who find in-ear headphones annoying and over-ear headphones too bulky.
Having said the most logical use of this product, let's move on to the price, a fundamental factor in choosing each product. Our BM-CT3 PRO they cost around €100 on the list price but we can find them on AMAZON with a 20% discount. At €80 I think it can be considered a really wise choice but if we add our personal coupon to this price you can take them home with an incredible discount equal to 40% approximately and at this price, if you are looking for a product like this, you would be crazy not to take the opportunity to purchase them.
