B5 Wireless Bluetooth 4.0 Headset with 40mm Drivers and 3.5mm Stereo Interface
The B5 Wireless Bluetooth 4.0 Headset is an over-ear, head-mounted audio device that supports music playback and multi-point connection. It combines Bluetooth 4.0+EDR wireless technology with a 3.5mm stereo audio interface, giving you two ways to listen. The stereo channel output and 40mm speaker are stated specifications, while the frequency response range covers 20Hz–20KHz. Output power is 2*10mW, sensitivity is greater than 85dB, and the signal-to-noise ratio is 80dB. Working voltage is 3.7V and working current is 70mA. The headset comes in black, silver, and red. The source also lists gift occasions such as opening ceremonies, awards commemorations, anniversary celebrations, advertising promotions, trade fairs, and festivals, making it suitable for promotional or commemorative use as well as everyday listening.
Features and Construction
This section covers the stated technical features and the physical design of the B5 headset. The information below is limited to what the source text provides, so no additional performance claims are made.
Material and Build
The source does not specify the exact materials used in the B5 headset. What is known is the over-ear, head-mounted wearing style and the colour options: black, silver, and red. The speaker size is 40mm, which is stated but not explained in terms of performance. The electronic specifications include Bluetooth 4.0+EDR, output power 2*10mW, sensitivity greater than 85dB, signal-to-noise ratio 80dB, working voltage 3.7V, and working current 70mA. These figures describe the electrical characteristics of the headset as listed in the source.
Size and Practical Fit
No overall dimensions or weight are given in the source text. The only size-related measurement is the 40mm speaker. The audio interface is a 3.5mm stereo jack. The head-mounted design is intended to be worn over the ears, but no headband adjustment range or ear cup dimensions are provided. Because of the missing data, it is not possible to state how the headset fits different head sizes or how much it weighs.
Uses and Placement
The B5 headset can be used for listening to music and for multi-point connection between Bluetooth devices. It also has a wired option through the 3.5mm stereo interface. The source mentions specific gift occasions, which suggests it may be appropriate for promotional or commemorative purposes.
Event or Professional Use
The source lists gift occasions including opening ceremonies, awards commemorations, anniversary celebrations, advertising promotions, trade fairs, and festivals. These suggest the headset could be given as a commemorative item, a promotional giveaway, or a trade fair gift. The multi-point connection feature may be useful when switching between a phone and a computer, for example, but the source does not describe specific professional scenarios beyond the gift occasions listed.
Everyday Home Use
For everyday listening, the B5 headset supports music playback and has a stereo channel output. The 40mm speaker and 20Hz–20KHz frequency response range are stated for audio reproduction. The 3.5mm stereo audio interface allows wired connection to compatible devices when wireless is not needed. The over-ear design is worn on the head, and the three colour options—black, silver, and red—offer some choice for personal preference. No noise cancellation, microphone, or battery life details are given in the source.
Benefits and Buying Value
The main practical benefits come from the dual connectivity options (Bluetooth and wired), the multi-point connection support, and the colour choices. The source does not provide price, warranty, or durability information, so value is limited to the stated features.
Reuse and Low Maintenance
The source does not include care instructions, battery life, or maintenance details. The only reusable aspect implied is the multi-point connection, which reduces the need to repeatedly pair and unpair devices. The wired 3.5mm interface also provides an alternative when Bluetooth is not available, which may extend usability in different situations. No claims about long-term reliability or repairability can be made because the source does not mention them.
Why Choose This Product
If you need a headset that offers both Bluetooth 4.0+EDR wireless and a 3.5mm wired connection, the B5 model lists both. Multi-point connection is stated, which can be useful if you switch between two Bluetooth devices. The 40mm speaker, 20Hz–20KHz frequency response, 2*10mW output power, greater than 85dB sensitivity, 80dB signal-to-noise ratio, 3.7V working voltage, and 70mA working current are the concrete specifications available. Colour choices are black, silver, and red. The gift occasions listed may make it suitable for promotional or commemorative use. No other comparison or performance claims are supported by the source text.
