In June 2021, the price of the high-resolution music distribution service "Amazon Music HD" was significantly reduced from 1,980 yen (tax included) to 980 yen (780 yen for Amazon Prime members). You can listen to high-resolution audio sources for less than 1,000 yen. It was unthinkable until a while ago.
To listen to high-resolution audio sources via Bluetooth, you will need earphones / headphones and speakers that support "LDAC". However, since Bluetooth is a wireless communication standard aimed at low power consumption, it is not suitable for sending and receiving large amounts of data like high-resolution audio sources.
Since the sound is transferred in a compressed state, it is virtually impossible to faithfully reproduce a high-resolution sound source even if it is LDAC (LDAC is lossy compression). It's definitely a great codec for listening to music over Bluetooth, but it's not as good as a wired connection.
The most recommended way to listen to Amazon Music HD wirelessly is Amazon's Echo series, which supports "Wi-Fi" connection. If you think about it now, it may be a speaker developed for listening to Amazon Music HD.

However, Wi-Fi requires more power consumption than Bluetooth, so it is essential to secure power with a power cord ... but small Echo Dot (3rd generation), Echo Dot (4th generation) ) Has an integrated mobile battery, so if you purchase them, you can use it like a Bluetooth speaker.
The Echo series allows you to enjoy "volume" and "high resolution" that are incomparable to Bluetooth speakers in the same price range even with low-priced models. If you want the highest quality sound, don't hesitate to choose Echo Studio.
Equipped with a total of 5 speakers such as "5.25-inch woofer", "2.0-inch midrange speaker", and "1.0-inch tweeter", the three-dimensional effect and expressiveness of the sound are perfect. The size is several times larger than the Echo Dot, but there is a sound that can be heard because of its large volume.
Echo Studio that also supports 3D sound playback. Recommended for those who want to enjoy three-dimensional and realistic sound with one unit without using multiple speakers. It is also possible to build a home theater system by combining it with the Fire TV Stick.
You can enjoy the high resolution sound source of Amazon Music HD in high resolution, and the Echo series is also very useful as a speaker for watching movies. Now that Amazon Music HD has been reduced in price, it's the best time to buy!
How to connect the Echo series to your Fire TV Stick (3rd generation), Fire TV Stick 4K, Fire TV Stick 4K Max as a home theater
Make sure that any of the "Fire TV Stick (3rd generation)", "Fire TV Stick 4K", "Fire TV Stick 4K Max" and the "Echo" series are "online". Next, open the Alexa app on your smartphone and select "+" in the upper right from "Devices".
Select "Set up audio system".
Select "Home Theater".
If the Fire TV Stick is already paired, a warning mark will be displayed as shown in the image below. In that case, return to the "Device" item and cancel the pairing.
After canceling the pairing (if you don't need to cancel it, you don't have to do anything), select the Fire TV Stick and click "Next".
A list of connectable "Echo" series will be displayed, so select "Speakers to be used as a home theater". Up to 2 same speakers + 1 subwoofer can be selected.
When two speakers are selected, the "Stereo Channel" test screen is displayed. Select "Left" or "Right", and if you hear the sound from the correct direction, leave it as it is. If you hear from the opposite direction, select "Switch Speakers" and click "Next".
Specify "Audio system name" and click "Next".
Select a home theater Select "Group" and then "Save".
If the name of the audio system is displayed in the speaker group, the pairing work is completed.
If two speakers are connected, the stereophonic sound in the 360-degree direction will be further "two-channel" and "stereo playback". I tried connecting "2 units" of "Echo Dot (3rd generation)" as a home theater, but it's pretty dangerous. If you want to build a small and full-scale home theater, please try it!
