★★★★☆ The new Echo 4th Gen is a big change in aesthetics and design for the Echo line. The new spherical shape is wider and shorter than previous Echo versions, and now focus sound in one primary direction instead of 360 degrees. It adds an extra tweeter, and seems to produce more sound than previous versions. Here are my early thoughts so far, after using it for about 24 hours:THE GOOD:Setup was incredibly simple. I just powered the device on, and the Echo announced that it was ready for setup. I opened the Alexa app on my phone, and the new Echo was automatically detected and set up instantly. I didn't have to enter any information at all. It can't get any easier than this.BETTER SOUND. This new Echo has an extra tweeter, for a total of two 0.8 inch tweeters, and the same 3.0 inch Sub from the Gen 3 Echo. This new Echo is designed with the tweeters pointed forward, and the speaker placement seems to generate more bass also somehow, even with the same Sub as the Gen 3. All in all I think it sounds much better than Gen 3, with a little more bass and louder max volume. This could also be do to the sound-mapping feature that allows Echo to maximize the sound by detecting the acoustics and shape of the room. You can also pair two of these in stereo; and you are supposed to be able to use it as a speaker for your FireTV device, though I haven't tested that out yet.Temperature sensor included. Yes, you can ask Alexa what the temperature is, and it seems very accurate so far. This is a nice touch, and I look forward to doing more testing, to see if I can set up routines based on temperature.AZ1 Processor. This new Amazon processor promises better voice recognition and faster Alexa responses. In my testing so far, I have barely noticed a slight speed improvement (for example turning on certain room lights) but there are supposed to be upcoming updates that will make an even bigger difference in speed.Zigbee + Sidewalk Bridge. This comes with a Zigbee hub, just like previous versions of the Echo Plus. It also contains the new Sidewalk Bridge, which allows the Echo to use bluetooth and radio connections to connect to some smart devices at long range, and push data to the internet.THE BAD:No 360 degree speakers. While I personally prefer the sound of this new version, some people might miss the 360 degree speaker setup of previous Echo generations. It certainly might lead to a situation where the ideal placement of the Echo in your room could be different.White power cord. This is minor, but a strange choice. No matter what color Echo you get, the power cord is white. Some people might find that annoying.Voice detection is not great while loud music is playing. This surprised me, as previous generations haven;t really struggled with this in my experience. I'm not sure if it is because this speaker is much louder, but Alexa hasn't heard me a few times when I talked while the music was playing at max volume. This could be annoying if you often listen to very loud music.NEUTRAL: -Aesthetics. I think I preferred the look of the cylinder design, instead of this new sphere shape. This is totally personal preference of course. I also wish the entire sphere was fabric, instead of being plastic on the back side. Some people might prefer the ball shape though, so that is up to you.All in all, I'm keeping this new Echo because of the better sound and faster responsiveness, but it is not really a massive upgrade. Pretty decent so far, I'll update this review and try to answer any questions in the future!

★★☆☆☆ I actually prefer the more balanced sound from my echo plus (2nd gen) without needing to mess with the equalizer. I also prefer the 360° sound from the echo plus. after going back-and-forth I’ve personally experienced the microphones on the echo plus pick up my voice better. in my opinion this new version just sounds a little bit louder with more bass even though they both have the exact same drivers with the exception of the new one having an extra tweeter which doesn’t really make a difference in the sound. I actually had to turn down the bass just a little because it sounded a little... messy. i’m not really sure why they completely changed the design and got rid of the 360° sound and made it a directional sound speaker instead. i’m a little confused. One more thing I noticed about the new speaker is when the volume goes up the bass goes down which is very common for all these speakers and most Bluetooth speakers but it seems especially evident in this newest version of the echo. they could’ve at least made the bluetooth option volume sync with your phone with this new version. and of course it wasn’t compatible to pair with my echo plus for stereo. ok i’m done.

★☆☆☆☆ - Inconsistent when responding - sometimes will answer you from 10 feet away, sometimes won't respond from 3 feet away. Hot/cold.- On some occasions, will understand you perfectly - better than you expect. At others, you wonder if you're on the same plane of existence.Speaking of Echo though, I do like the sound quality. It does sound bassy but I think there's a higher degree of clarity. I tested this by playing "50 ways to lose your lover" (aka Steve Gadd's iconic drum groove) on Echo 3rd gen and 4th gen. The song sounds so much better on the latter.Anyhoo, the model in question has poor listening skills on account of which, I rate it a glorious 1 star.

★★★★★ 1.) It's a Bluetooth receiver only, not a transmitter. It RECEIVES audio via Bluetooth radio from remote devices such as laptops, smartphones, desktop computers, or any devices that transmit audio over a Bluetooth carrier signal - only one device at a time. It WILL NOT SEND/TRANSMIT a signal over the air TO any other device. I'm not trying to belabor the point or be sarcastic, but some of the questions I've seen seem to indicate confusion as to whether it transmits and receives, or just receives.2.) It feeds the audio it receives to an amplifier as a LINE-LEVEL signal via a stereo signal cable (provided) - RCA to 3.5mm or vice-versa. You can use the cable either way depending on your amplifier's input jacks. Both the RCA and Aux. jacks on the Esinkin are line-level OUTPUTS; just use whichever one you need. If necessary, you can use your own cords or adapters to make the correct connections to your amp.3.) Will it drive speakers? ONLY IF they are Powered Speakers, meaning each speaker has its own built-in amplifier. It WILL NOT drive non-powered speakers directly without amplification. Headphones? Probably; I haven't tried it. It would depend on the headphones, and since there is no volume control on the receiver, you would have to be able to adjust the volume at the source: phone, laptop, etc. Proceed with caution so you don't wreck your headphones or your hearing with an initial super loud blast. You know how getting blasted makes it nearly impossible to find the volume control or rip the phones off your head without hurting yourself.4.) Power Supply - It comes with its own plug-in supply and cord, and that's the only way to power it. It WILL NOT run off a USB supply or port on a computer. The input is keyed to the cord supplied with the AC adapter. If that fails, you could probably find replacements.5.) Performance: I am pleased with the quality of the sound. I use it as an input to a 160 watt rms (80 X 2) Onkyo TX-8050 stereo receiver driving 2 pretty decent Pioneer speaker systems from the early 1990s, and it sounds about as good as strong FM reception or CD playback. I don't use the NFC function, so can't comment on that. Range is easily 25 feet, which is no problem for the layout of our living/dining areas. It seems to sync up quickly with my Bluetooth devices.I would recommend it, based on our experience so far.

★★★★★ I'm using it with my Echo dot to allow Alexa to play music through my Yamaha receiver. The Echo connects quickly and seamlessly. And the best part is when I tell Alexa to disconnect, the Echo disconnects and stays disconnected.

★★★★★ It was so easy to connect, easy to pair, works excellent. I have a old school stereo receiver with rca jacks, sounds very clear.
