When it comes to studio-grade headphones, many people may immediately think of professionalism, high prices, and a distance from ordinary users. However, this stereotype is actually inaccurate. For example, the Bowen Fei Para50 headphones I have purchased, which feature studio-grade sound quality and a dual-mode design, are more suitable for daily use and are very affordable.
The Beyerdynamic Para50 headphones, as a pair of headphones with monitor-level sound quality, emphasize "reproduction" in practical use. In terms of style, they lean towards neutrality and objectivity, without pursuing a unique sound style. This design will actually be more appreciated by experienced music enthusiasts and is also suitable for creators.
Next, let's share our experience with the Byrnefei Para50 headset, a dual-mode Bluetooth earphone, starting from its exterior design and moving on to its overall sound quality.
Appearance ｜The gift box version is well-designed and excellently crafted
Let's first take a look at the appearance and detailed design of the Bose QuietComfort 50 headset with dual-mode Bluetooth.
First, let's introduce the brand, Bornfree.
Brianfay (B&F): A professional brand in China specializing in wireless audio, founded by a team of professional sound engineers, dedicated to providing services for musicians.
Ordinary users may not be very familiar with it, but the wireless system for musical instruments under the brand of Beyonfei has been ranked among the TOP 3 in the music equipment category on Amazon's US site for three consecutive years! Moreover, it is highly renowned in the domestic music industry and has collaborated with numerous bands and artists.
The Bose QuietComfort 50 headphones I experienced this time are a new product from 2025. A special gift box version has been launched, which can not only be purchased for personal use but is also very suitable for giving to music lovers.
The specially designed storage bag is highly praised! It is more suitable for carrying when going out. After all, it is a dual-mode design that is applicable in more scenarios.
Packing List
Bernfly Para50 dual-mode Bluetooth headset, accessory storage bag, Type-C charging cable, 6.35 to 3.5 conversion head, 3.5mm audio cable (1.8m).
You may not be familiar with the 6.35mm connector, which is mainly used for professional audio equipment such as mixing consoles.
In terms of appearance, the Bernfei Para50 dual-mode Bluetooth headset is indeed well made, with an overall fashionable style, but the gold accents also give the headset a retro element.
There are two more details in the design, the RGB lights are hidden inside the earmuffs.
Not only does it support constant on and off, but it also supports rhythm jumping, adding more technological elements to the headphones.
The interfaces and buttons of the headphones are very rich, from left to right, including a pickup microphone, Type-C charging port, 3.5mm audio interface, up and down function buttons (short press during music playback can also be used as volume adjustment; at the same time, Changan can turn on RGB lights), volume adjustment dial, and power on/off button.
Let's take a look at some details of the design of the Bernfei Para50 dual-mode Bluetooth headset.
Firstly, the design of the volume control dial adds a vintage style.
Secondly, the sponge wrap of the headband design is very thick, and the top pressure is very low after wearing.
Thirdly, the design of the adjustable head beam adopts a metal adjustment arm, which is more sturdy and durable.
Fourthly, the protein skin earmuffs are very soft and support disassembly and cleaning.
As a head mounted earphone, the Bernfei Para50's earmuffs have excellent physical sound insulation. Whether it's listening to music in daily life or using tools for creation, they can all achieve immersive listening effects.
Powerful hardware design with a more pure listening style
The hardware design of the Burnfly Para50 is still excellent.
The most concerned sound unit is a 50mm high-sensitivity dynamic coil unit with an impedance of 50 Ω. The impedance is not large, and when using priority connection, it can be easily pushed without the need for a high thrust front section. The frequency response range is 15Hz-20kHz, and the ultra wide frequency response range also makes me very excited about the three frequency performance of the headphones. The Bernfei Para50 adopts a powerful dual cavity frequency division system, where independent cavities can distribute signals of different frequencies to different cavities to achieve better sound quality.
Here, it should be noted that wired connections of headphones can result in less signal loss, while Bluetooth requires compressed audio data during transmission, and even higher encoding and decoding technologies cannot avoid sound quality loss.
That's why our sound quality testing process abandoned the Bluetooth mode that we prefer for daily commuting, and instead used a professional music player and wired connection to deeply test the sound quality effect of the Burnfly Para50.
On the front-end, I chose ACTIVO CT10.
Firstly, the low-frequency sense and texture are really well done. When I started listening, I even took off the headphones and looked at the brand again. I was surprised by the significant progress in sound quality made by domestic manufacturers, and the excellent diving performance of the Bernfei Para50, 《THE WAITING GAME》、 The music pieces "Sky" and "Dust Drum" exhibit a very distinct sense of hierarchy, and the instrumental performance is excellent.
As a monitoring grade headphone, the Bernfei Para50 does not have too much intervention in sound quality, ensuring more authenticity. For example, the mid-range that people are concerned about is more about pursuing restoration, such as the classic Zhao Peng's "Song of the Boat", where the recognition of vocals is very high, and the rich voice is expressed very naturally. The details of the sound are precise and the contours are very clear, and authenticity remains the biggest feature.
And one of my favorite high-frequency representative works, "Just Like You", the performance of the Burnfly Para50 surprised me greatly, with clear details and excellent transparency. This song uses a lot of strings, piano, and so on, and the Bernfei Para50 performs very well in terms of details, with no distortion at all.
The performance of Bernfly Para50 is actually more suitable for creators, especially some music creators. The vocals and instruments ensure high fidelity, rich details, and excellent tri band performance.
Of course, the biggest advantage is that as a product that sells well overseas but belongs to an emerging brand in China, its cost-effectiveness is extremely outstanding. This is also the reason why the price of monitoring grade headphones may not necessarily be expensive, as mentioned at the beginning.
Overall, I think the Burnfly Para50 is definitely worth buying for music enthusiasts.
