The headphone impedance depends on what equipment these acoustic devices will work with. For example, for conventional stationary devices, audio accessories with a recommended impedance of 120-150 ohms are suitable. And for a phone, tablet, and player, much smaller values \u200b\u200bare suitable, only 16-40 ohms.
For a computer, or a music system, you need full-size high-impedance headphones with an impedance of up to 120 ohms. These are devices with an output voltage greater than 4 V. Only stationary devices connected to the mains can give such a high value. Therefore, to connect with them, you should select accessories with the appropriate impedance.
With a high output voltage (more than 200 mV), it is better to choose “ears” with low sensitivity, with a resistance level of 32 ohms. They use less electricity. High-impedance audio accessories require a special audio amplifier to function successfully.
Pros and cons of TWS headphones
Now consider the main advantages and disadvantages of wireless headphones. Let’s start with the strengths:
Pros
- No wires. The earbuds won’t get tangled up in your pants pocket and won’t stop working if the wire breaks.
- Freedom of movement. While cleaning in an apartment or subway, you don’t have to worry that the headphones will catch on a wire with an object and fly out of your ears.
- Gadget independent. You can put your phone or tablet on charge in the bedroom and safely go to the living room. At the same time, the music in the headphones will not stop playing.
Minuses
- The weight. TWS headphones weigh more than conventional wired solutions. This is because they have a built-in battery that allows the headphones to work without wires.
- They are easy to lose. Probably the main problem with wireless headphones. One “ear” can be easily lost, and it will be very difficult to find it.
- TWS headphones cost 3-4 times more than classic options.
- Recharging required. Wireless headphones work for 3-5 hours of active use, after which charging is required. This is inconvenient if there is a long flight ahead or a trip without power outlets.
How to choose active headphones?
When choosing active headphones for hunting, you need to consider:
- The presence of volume controls.
- Cut-off speed of the model you like.
- Ease of management.
- Fastening design.
- Level of protection against moisture.
- Availability of connectors for connecting external devices.
In modern models, it is possible to fine-tune the required volume level of the “soundtrack”. By purchasing these headphones, you can choose which sounds to muffle and which ones to amplify. Since the hearing of each person is individual, this feature is very useful. In this case, the advantage will be the ability to change the volume of the right and left speakers separately. If you hear worse in one ear than the other, this fine-tuning feature will allow you to perfectly adjust the headphones for you.
Clipping is the delay in audio that can occur as the signal travels from the microphone to the speaker. The smaller it is, the better, ideally it should not be at all. A pronounced cutoff will create inconvenience.
Also, when choosing, you need to pay attention to how the control buttons are located and how easy it is to use them.
Do not forget that the device will probably have to be used in quite extreme conditions – it is important to be able to quickly adjust the headphones
Active headphones can be attached with a headband that goes over the head, or with a headboard that sits at the back of the neck. The first option is well suited for use in the warm season when you put on a light and thin hat or go hunting without it.
The battery compartment must be especially well protected against moisture. Also, all other electronic components need protection – microphones, speakers, and so on. When hunting, headphones can not only get caught in the rain – but there is also always a chance that during active movement they will fall into the water.
