Guide how to choose Bluetooth Headset. The most common dilemmas and doubts

Posted on Posted in Headphones

The domain of wireless headphones is definitely not the sound quality. This problem specifically relates to Bluetooth technology, which typically uses the A2DP (Advanced Audio Distribution Profile) profile. If we listen to lossy music (such as popular MP3s), it will be re-compressed during transmission, which further aggravates the average quality.

Connections using traditional radio signals (2.4 GHz) provide slightly better quality, but they also have their drawbacks, such as signal delays or noise. Some models also have limited sensitivity – they only start to sound at the right volume and turn off when the volume drops.

What is the difference between earbuds and earbuds?

Mostly comfortable to use and easy to carry. When it comes to comfort, there are probably as many people who prefer earphones as well as earmuffs. But in terms of mobility, however, the first ones dominate – we usually fit them together with the cable to the smallest pockets in the pants.

Earphones typically include larger diaphragms that have a positive effect on the quality of the reproduced sound.

What are intrinsic earphones?

These are structures that are partially inserted into the inside of the ear, but unlike earphones, they require sealing of the ear canal. They are usually fitted with one or several silicone gaskets that perfectly suppress ambient noises. Headphones are miniature equivalents of closed earphones.

When to choose a handset that dominates the bass and what models?

If we listen to dynamic music (eg strong electronics, hip-hop) we should pay attention to the good, strong, pulsating bass in the headphones. Receiving music is a completely individual matter, so we are not able to recommend specific models, but many manufacturers have “DJs” in their offer. Such constructions are optimized for strong, dynamic, pulsating music.

However, if you are listening to stringed music (such as cello), excessive bass may interfere, and DJ designs may cause poor bass distortion.

How long does a wireless headset work on a single charge?

Working time can vary widely. Depending on the manufacturer, small portable Bluetooth headphones can withstand from 5 to 10 hours of play at 50-75% volume. Headphones with larger rechargeable batteries will last for a dozen hours, and large interchangeable battery designs will work on average between 15 and 25 hours, although there are also models withstand 30 or even 40 hours.

In addition, we can replace standard batteries with larger capacity cells. It is often the case that the AAA batteries included in the kit have 600 mAh, and in the “corner kiosk” we are able to buy 1000 mAh models for a small fee, which significantly increases the working time.

Can the docking station attached to the headphones only be used for charging?

Yes, the Philips SHC8525 wireless headphones can serve as an example.

Will the long-term use of the headphones not damage my hearing?

It’s an individual issue (each of us reacts in a slightly different way). It can be assumed that the upper limit during long listening will be 80 dB, but none of us will after all listen to music with the acoustic pressure meter under the handset. My site … If there is a situation in which we experience pain in the ears, we should immediately turn off the music or at least clear it.

What should have earphones to keep from falling out when running?

The best earphones are the earbuds. Silicone gaskets ensure that the handset is not torn from the ear and that the headband improves stability and prevents slipping. Also check structures with a single headband.

What is the principle of surround sound in headphones?

Surround sound in the headphones is achieved by a few small speakers located in key places. Each of them is responsible for playing a separate sound channel – for example, front (stereo), rear (stereo), central and two main diaphragms working as a midrange driver. The number of plugs depends on the number of channels.

What exactly are earphones referred to as audiophiles and who should you recommend them for?

Audiophile headphones are designed primarily for people with high sensitivity hearing, for which the sound reproduction perfectly pure and consistent with the original is a passion for life. No compromises are made when designing and creating such headphones – all materials are of the highest quality. Membranes are not plastic or paper, but are made of special microfibers, for example, and reproduce even the most delicate nuance of the sound.

The frequency range of the audiophile headphones is much higher than that of the average “emp-to-ear” headphones. In fact, the range is so large that it exceeds the human hearing capabilities (for example, the Denon AH-D7000 or the AH-D2000 offer 5 – 45,000 Hz), and everything to suit even the most sensitive hearing impaired.

The left and right high-end headphones should be of the same length and made of 99.99999% oxygen-free copper (eg 7N-OFC). At the end of the cable should be a gold plated plug of 6.3 mm or possibly 3.5 mm with the option of tightening the adapter to 6.3 mm.

Reproduction of the sound closest to the original also requires that the audio track be stripped of all the bewilderment and artificial enhancements that actually change the sound to something that is not compatible with the original. Audiofilter devices should offer the option of turning off any interference with raw audio recorded on the media.

High-end headphones must achieve a (high) quality ceiling, but definitely the most important is the pleasure of listening to music. So if you choose audiophile headphones for 2, 5 or even 2 thousand dollars, the first thing we take is to visit the living room and listen to the reference gold disc, using a reference SACD player, amplifier and several selected headphones.
