The Cheapest Price, Best Selling High Tech Products 2019


Quality at the cheapest prices on the web

What is a connected or smart speaker?

Called both connected speakers and smart speakers, a phrase dear to many. It is a High-Tech product, then it's a speaker connected directly to the internet via Wi-Fi. This connection allows you to benefit from an integrated voice assistant.

At the start, the initial main function was the broadcasting of music but it was not interesting. Today several functions have been added to give the best use and get out of a simple enclosure.

Several manufacturers make sound quality their first objective while for these qualities come last.

A connected speaker (often a portable speaker), like the Bluetooth speaker will allow you to listen to music in two ways:

- By Bluetooth from a smartphone or tablet,
- By streaming from applications.

Several forms and models exist, the wireless or portable speaker, the compact speaker, the multiroom speaker, the small speaker or the large.

How it works ?

Wireless speakers use applications called skills. And adding these skills to the Amazon Alexa parent apps for Amazon Echo, etc., Google Assistant for Google, etc. and Siri for Apple, previously downloaded, you can access the desired functions.

Thanks to these skills, we will be able to add interactive functionalities to the speaker: radio, games, traffic, newspapers, etc.

For home automation, it is necessary to activate the skill on the speaker as well as the appropriate application on a smartphone.

What to expect?

There are many uses. The most common are:

- listen to music in multiroom,
- make calls,
- listen to news,
- ask questions,
- program alarms and timers,
- check the weather and sports results,
- manage lists of things to do,
- schedule purchases or make reservations,
- drive the house by equipping itself with the connected kit,
- locking the doors,
- centralizing the control of systems at home,
- etc.

Piloting is generally done by voice.

The prices offered are the same as those charged by the parent companies.

Amazon range

The Amazon company, pioneer in this field, presents several models of High Tech articles:

Google Giant range

The giant has also launched three High Tech products called "Home":

- la Home,
- la Max,
- la Mini.

He integrated all of his armada, Gmail, Google Photos, Google Drive and others to get the most out of it.

He integrated several features into his devices. Those not listed require the use of other tools and services.

Home replaced by Nest Audio

- This connected speaker has a good quality/price ratio.

The Max

It is a premium, smart and connected speaker. Personalization is at the center of Google’s concerns in this device. This is how, in a household of several people, she distinguishes voices and is not mistaken when someone asks her to do something for him.

The Mini

He's the little brother of the first Google Home. It takes the form of a small pebble running Google Assistant, Google’s artificial intelligence.

It is an entertainment, assistance and control system for connected objects, capable of responding to the user's voice requests. It can also access all the services offered by Google.


- two omnidirectional microphones,
- a 40 mm speaker,
- volume control is done by tapping the sides of the device to increase or decrease the sound.

The only physical touch to the device is on the back of the speaker. It is used to activate or deactivate the assistant's microphone.

Apple range

Apple already launched its product in 2018: The HomePod which claims to be the rival of Google and Amazon. For this, he bet on the quality of his product.


- it measures 170 mm in height and 142 mm in diameter,
- it weighs 2.5 kg,
- it is wireless and has Wi-Fi and Bluetooth.


- seven horn tweeters, each with its own specific amplifier,
- six microphones and deep bass,
- dynamic processing worthy of a professional studio.

It was presented as a “Home Assistant”. Several requests (weather, internet research, news) can be done thanks to the Siri Assistant (weather, internet research, news) which it will process thanks to the Siri Assistant.

Other types

Here are some of the connected speakers that are currently on the market: We can't speak of a better speaker. There are always improvements.

- Sony LF-S50G,
- Onkyo smart speaker P3 and V3,
- Panasonic SC-GA10,
- JBL Link20,
- Libratone Zipp,
- Harman Kardon Allure and Invoke,
- LG ThinQ.

And then there is a speaker that emerges from all the others. It's the Sonos one. It is certainly one of the best models on the market and has sound power with impeccable audio quality and stereo sound.

This compact Wi-Fi speaker from Sonos is sold in France but does not yet have all the new features: Alexa, Google Assistant, AirPlay 2 for the French language.

The One de Sonos

- Dimensions 162x120x120 mm,
- Weight 1.85 kg,
- Two finishes, black and white,
- Touch interface.

- Microphone deactivation function,
- Respect for privacy using an LED,
- Equipped with multiple microphones.

Voice control is not supported in more than one country. In addition, skills are added over time. On the other hand, you should know that there are wall mounting kits and suitable supports but which are enormously expensive on the site of the enclosure.

Kardon Harman's Citation One

Specificities - Dimensions 140x188x140 mm,
- Weight 2 kg,
- Wireless network 802.11a/b/g/n/ac,
- Microphones with high quality.

The Citation One is a speaker with sophisticated design. It is the ultimate in advanced audio. It is focused on the Google Assistant which allows you to:

- Get answers to your questions,
- Listen to music (300 broadcasting services),
- Order your home automation.


The factors that push you to buy this or that speaker are:

- The quality of the voice assistants and compatible applications,
- The quality of the sound, the sound system and the amplification of the loudspeaker or loudspeakers,
- The design, the hands-free kit,
- A speaker inexpensive, at the lowest price.

In 2017, the Amazon Alexa occupied the first place of sales with 70% of the market while the Google Home was placed in second position with 23% of sales.

Since the beginning of 2018, another speaker is talking about it, it is the Sony LF-S50G which has an irreproachable sound quality and other new functions.

The quality speakers, the best connected speakers, portable or not, are built around a Hi-fi amplifier of a few watts. They use 802.11b/g/n Wi-Fi or ac and the 2.4 Ghz and 5 Ghz frequency bands. They are sold with their hands-free kit.

   All of them are currently using advanced voice assistants Alexa and Google (OK Google, Bose Surround).

   And finally, plugging in your Hi-fi speaker is a plus. It allows you to add sound to the home through dialogue thanks to its integrated assistant.

Invasion of privacy

We are taking here extracts from the article of CNIL France (National Commission for Information Technology and Liberties) of 12/20/2018.

Operating steps

The operating principle of a smart speaker goes through 5 steps:

- Step 1:
The user gives an order using a keyword,

- Step 2:
The key word pronounced "awakens" the speaker. Some speakers use voice biometry, that is, to have the user record samples of their voice for one reason or another. This data is collected without the user's consent.

- Step 3:
The user provides his request. There are two possibilities:
  . Queries are saved locally,
  . The requests are sent in the cloud, that is to say on servers which keep a request history as well as the corresponding data (date, time, etc.),

- Step 4:
The speaker response sentences are first transcribed into text and then synthesized on the speaker,

- Step 5:
The speaker is on standby.

Vigilant point

Three essential points must be respected in order not to harm his privacy. These 3 points of vigilance are:

- First point: Confidentiality of exchanges

If the speaker detects one of the pre-recorded keywords, it can activate and save the conversation, even if it is on standby. To remedy this:

. It is necessary to privilege an enclosure equipped with a button of activation and deactivation of the microphone,
. You have to mute the microphone or turn off the device when you don't want to be listened to,
. You have to warn everyone around you at home,
. Above all, it is necessary to supervise children's interactions.

- Second point: Monetization of the ultimate

The enclosure is at the center of home life. Home living habits are discovered in the presence of the enclosure. The advice provided by the commission is:

. You have to connect services that are really useful for you,
. We must be vigilant about everything that is said in front of the device.

- Third point: The absence of a screen

The absence of a screen does not allow us to have an overview of all recorded data. The advice recommended in this case is:

. You always have to go to the "dashboard" to delete the conversation history.

News: Connected speakers

The main news of the moment is as follows:

- It will soon be possible to pay your bills with Alexa. The complete file which also speaks of the skills available in French and the pre-programming of Alexa and Amazon Echo can be found at the following address: Journal du Net
