Do Not Bother Others with Your Loud Music, Putting On Your Over Ear Headphones or Earbuds

“Why do you do it? Can't you use headphones? My wife and I have been doing a bunch of hiking lately in the San Gabriel and Santa Monica mountains. Every time we have run into multiple people hiking while playing loud music from their phones or speakers. The reason I go hiking is to escape from city life and enjoy nature, but it's much harder when I keep hearing rap music reverberating around the canyon walls. So frustrating.” A netizen wrote on Reddit.

There are over 300 comments below this topic. Most reply support the original poster, they all think that it’s annoying. Someone shared their similar experiences on the topic. Of course, I don’t like the people who blare music out on public. Why not put on your headphones for music? If you don’t like wired headphones, you can choose wireless Bluetooth headphones. There are lots of Bluetooth headphones on the market. I’m sure you will find the most suitable headphones for yourself.

Mixcder, a new brand of Bluetooth audio devices, they provide many types of Bluetooth headphones, and the price is very reasonable. For example, ShareMe series, it allows you to share you music with your family or friends with two ShareMe headphones, only for 49.99$. ShareMe is very comfortable to wear, and has long battery life up to 18 hours playing time.

If you prefer earphones, PRO911 wireless Bluetooth In ear headphones or X5 wired earphones with mic is for your choice. I have bought PRO911 for workout. With wireless design, sweatpoof features, it’s very good for gym use, I love it.  By the way, Mixcder will offer coupons sometimes. Please do remember to visit Mixcder official website for coupon code.

 

In a word, for those people who like listening music with speakers on public, this is a recommendation for you to replace your speakers with headphones. Thanks.

Bluetooth Headphones with aptX low latency or aptX HD headset, How to choose?

Le 19 septembre 2017, 09:12 dans Musique 0

Pertaining to audio, aptX is advertised as the means of achieving CD quality sound, wirelessly! What is AptX? Get to start to understand aptX, you’ll need to know how digital audio works.

Digital audio is a compilation of audio signals encoded in a digital format that can be used to record, store, generate, and/or reproduce sound. As CNET so eloquently explains, a sample of the collection shows what a sound wave looks like at a specific moment, like a freeze frame. With enough of these freeze frames put together these frames can be converted back into a smooth sound wave by a device designed for digital playback. CD-quality refers to rate of 16 bit/44kHz which accounts for 44,100 samples every second and where each sample has a value between 0 and 65,535 (referred to as "16-bit").

Digital playback devices can play 16 bit/44kHz though this rate isn’t easily streamed via web or say wireless device as it’s about 10MB in size. MP3 files are much smaller (at about 1MB) and easier to stream because they are compressed. Bluetooth is a global wireless communication standard that allows for the easy exchange of data over short distances. Translation, only so much data can be transferred at one time down the tiny Bluetooth pipeline. Wi-Fi would allot for much more. So if you’re sporting over ear Bluetooth headphones but want to hear the best in audio quality, your device is going to need some help.



This is where aptX comes into play. It is a codec algorithm that compresses the digital audio signal by removing parts of the audio that aren’t noticeable by the listener and cause the least amount of impact on the fidelity of the audio.

AptX Director of Sales and Marketing, Johnny McClintock explained more to LifeWire, “AptX runs at 354 kilobits per second, and it’s a fixed 4:1 compression ratio so the performance is guaranteed… SBC and MP3 and AAC have more aggressive compression and are thus far more efficient than aptX. But if you have the capability of addressing more bits it’s going to sound better.”

There are two types of aptX you’ll see on most devices today. There is Qualcomm aptX HD and aptX low-latency. The HD version supports 24bit/48kHz LPCM audio data which is better than CD-quality (44kHz/16bit) to better enhance audio quality. As for low latency Bluetooth headphones, this version is best suited when watching movies and playing games as it reduces delay and ensures the audio is synchronized with the video. It supports a latency of less than 40ms and 48kHz / 16bit LPCM audio data.

 

For example, our new HD601 and MS301 are equipped with the aptX low-latency technology, which are definitely perfect for watching videos or playing mobile games.

Guiding To Pick Out the Right Headphones via Important Specifications (Part 1) -Make Sense of Headphone Frequency Response

Le 30 août 2017, 12:35 dans Musique 0

What do we care about when picking up a new set of over ear headphones? Some factor like the look and comfort are personal preference. Headphones specifications are a surprisingly complicated business. Today I’m going to explain headphone frequency response, and tell you how to identify the best headset via headphone spec.  

Frequency response indicates the range of audio frequencies the headphones can reproduce. It’s measured in Hertz, with the lowest number representing the amount of bass, and the highest treble. Most headphones have a stated frequency response of around 20-20,000Hz, which matches that of human hearing.

The numbers are not really a good indicator of sound quality, though they can help you choose the right headphones for a particular type of music. For instance, if you want lots of bass, then you should look for headphones that support a low bass frequency.

Learn to read headphone frequency response graphs

let's go over understanding headphone frequency response graphs. Often times reviewers use graphs to illustrate how great or poor is. You can better understand how well the wireless and wired headphone may perform by understanding how to read the graph. Again, this is not the only indication of how good a headphone is.

 

In theory, the line on a frequency response graph should be relatively flat line since the range demonstrates the headphone's ability to reproduce all frequencies equally. A "natural sounding" headphone is said to be slightly higher in the bass between 40Hz and 500Hz. That's where bass instruments and deep male vocals live, remember?!

If the line on the graph is slightly higher on the left side that means the headphones produce sound with more bass response. If the right side of the graph is higher than the left, that means the wireless headphones have a greater response in the mid, highs, and treble. That headset would be considered bright.

 

Bluetooth headphones have to compensate for the drivers being so close to the ear in the highs, so the highs are "rolled-off" and illustrated by a gradual sloping flat line from 1kHz to about 8-10dB down to 20kHz. In addition, small spikes at higher frequencies are normal as that is due to reflection cancellations in the folds and ridges in the outer part of the ear. But, sharp spikes in frequency (peaks and deep valleys) over 3,000Hz or so are indications of when the headphone sounds harsh.
