As Amazon‘s most popular voice assistant device line, the Echo Dot smart speakers make it easy and affordable to add Alexa‘s helpful voice capabilities into your home. With the latest 4th generation model launching in 2020, many wonder whether it‘s worth upgrading from their existing 3rd gen Echo Dot.
In this comprehensive guide, we‘ll compare these two top-selling Alexa speakers across all key areas – from design and audio to intelligence and sustainability. Read on for expert advice that cuts through marketing hype so you can decide if moving to the Dot 4 suits your needs.
Brief Background on Echo Dot Evolution
Launched in 2016, the hockey puck-shaped Echo Dot kickstarted Amazon‘s goal of placing an Alexa assistant into every room of the house.
"Alexa wasn‘t very useful in those early days – you could ask silly questions and maybe set a timer," recalls smart home enthusiast Gary Tan. "But the Dot‘s low $50 price really attracted techies who were curious about voice control."
With the 2nd generation in 2017, Amazon focused on improving the Dot‘s mediocre sound quality by increasing the speaker size to 1.6". This helped counter criticism of tinny audio output.
The popular 3rd generation followed in 2018 with a more stylish fabric design but the same 1.6” speaker setup.
"By then Alexa had gotten much smarter," Gary says. "You could use voice commands for shopping lists, weather reports, controlling smart lights – it was actually useful!"
Buoyed by rapid AI advancements from Amazon, over 100 million Alexa devices had been sold globally by late 2019.
The 4th gen Echo Dot landed in 2020 to positive reviews. While retaining the same compact form, Amazon looked to cement the Dot‘s position as an attractive smart speaker anchor suitable for any room decor.
Echo Dot 3 vs 4: Design & Physical Features
On the surface, both Dots share a similar hockey puck-style shape at just under 4" in height. But the 4th gen model sports a larger footprint by about an inch, as well as more rounded edges. It definitely stands out visually next to the more utilitarian Dot 3.
Dimensions:
- Echo Dot 3 – 43 x 99 x 99 mm
- Echo Dot 4 – 100 x 100 x 89 mm
Despite increased dimensions, the 4th generation weighs slightly less at 300 grams vs 338 grams for the 3rd.
In another contrast from previous generations, Amazon moved the simple LED lighting ring that indicates Alexa is active/listening from the top surface to the bottom rim.
Thanks to integrated motion sensors, the LED ring now also spins when you adjust volume – a nice extra visual touch.
The Echo Dot 4 loses the 3.5mm audio jack of its predecessor. However it retains Bluetooth support for connecting external speakers if desired.
Overall the newest gen feels more like an attractive smart home gadget versus a budget add-on.
“I love displaying my Dot 4 – friends always compliment its unique spherical shape,” says Stacey L., early adopter and smart home enthusiast. “The fabric finish and refined details make this an accessory I’m happy to show off.”
Winner: Echo Dot 4th Generation
With refined flourishes like the spinning LED ring and soft rounded edges, the 4th gen Dot clearly wins on aesthetics. The increased footprint also gives it a sturdier, more modern feel.
Sound Performance: How Audio Quality Compares
Given tinny sound plagued earlier Echo Dots, prospective buyers reasonably want to know how these two models compare sonically.
The good news is that both utilize 1.6” front-firing audio drivers – a major upgrade from the anemic 1.1” driver in the original.
In practice however, there are discernable audio improvements with the 4th gen including:
- Fuller bass
- Crisper vocal reproduction
- Up to 70% less distortion at higher volumes
- Wider supported frequency range (100Hz to 20kHz vs 100Hz to 18kHz)
Reviewers unanimously agree the latest Dot surpasses its predecessor.
“Finally, an Echo Dot with sound that matches its physical appeal,” raved Wired magazine. “This speaker can actually fill a room, unlike earlier generations.”
Echo enthusiast Gary Tan agrees:
“I was shocked at how decent music sounds on the Dot 4. You can really crank tunes to party levels without that tinniness making your ears bleed. Alexa also comes through loud and clear when issuing voice commands.”
The 4th gen sonic improvements stem from a unique audio architecture. In simple terms, the speaker is better optimized to suppress vibration, resonance and distortion.
Of course, the Echo Dot has never aimed to rival audiophile speakers. Those seeking deeper bass or stereo separation can still connect via Bluetooth or the 3.5mm jack on gen 3. But if choosing one, sound quality goes to…
Winner: Echo Dot 4th Generation
With a better driver enclosure, upgraded components and distortion-busting elements like anti-vibration silicone rings, the Dot 4 gives noticeably better audio reproduction that finally fits its physical footprint.
Intelligence & Features: What‘s Under the Hood?
You don’t get far in the world of smart speakers without serious AI power. Alexa development has progressed swiftly since first launching and both Echo Dot generations benefit.
But Dot 4 has distinct advantages from its newer Azure Sphere chip running Amazon’s AZ1 Neural Edge processor – a first for the Echo range.
Faster, More Accurate Alexa
With extra machine learning muscle, Alexa responds up to twice as quickly on 4th gen devices while managing requests more elegantly.
An example:
“Alexa, what’s the weather this weekend?”
Dot 3 response time: 6.2 seconds
Dot 4 response time: 3.1 seconds
This responsiveness delta is crucial for smart home gadgets, especially if you‘re controlling devices in rapid sequence.
The AZ1 chip also enables Alexa to parse conversations more accurately amid background noise. This avoids the frustration of shouting multiple commands when you weren‘t heard correctly the first time.
Proactive Home Monitoring
Additional components facilitate new Echo Dot 4 capabilities like:
- Care Hub – Lets you check in remotely on elderly family members also using supported Echo devices
- Guard Plus – A subscription service where Alexa listens for alarms, breaking glass etc. and can contact emergency responders
- Sound Detection – Sends alerts to your phone if the Dot hears smoke alarms or crying babies
These home monitoring features may appeal for users wanting extra security or to care for loved ones remotely.
Eco-Friendly Materials
The Echo Dot 4 introduces more recycled materials into manufacturing, including 100% post-consumer recycled fabric, plastics and die-cast aluminum. The latest gen is also optimized for low power consumption.
So inside and out, the 4th gen device pushes Amazon‘s sustainability efforts forward meaningfully – which may appeal for environmentally-conscious shoppers.
Winner: Echo Dot 4th Generation
With specialized hardware like Amazon‘s latest AZ1 processor unlocking huge Alexa IQ gains, plus innovative home monitoring options, the Echo Dot 4 is decisively smarter. Yet it retains full compatibility with over 100,000 Alexa "Skills" (voice apps).
Verdict: Which Echo Dot Should You Consider Buying?
In head-to-head comparison between Amazon‘s most popular smart speakers, the 4th generation Echo Dot consistently comes out ahead.
With gorgeous spherical aesthetics, noticeably better audio output and cutting-edge components making Alexa even more useful, the latest iteration leaves its predecessor in the dust while still staying affordable.
Consumers seeking an intelligent hub for controlling smart home gadgets or accessing Alexa’s ever-growing repertoire of voice skills will get the best experience from the Echo Dot 4.
Upgrading from the 3rd gen brings tangible lifestyle conveniences thanks to faster, more accurate Alexa responses and forward-looking features like home monitoring and elderly care tools.
Perhaps most importantly, the Echo Dot 4 finally produces room-filling, vibrant sound that matches its sleek modern design. No longer must buyers compromise between attractive styling and decent audio from Amazon’s entry-level smart speaker.
The 3rd gen Echo Dot is still a competent, budget-friendly choice for using Alexa in a basic capacity around your home. But splurging a little more for the 4th generation grants advanced capabilities that meaningfully enhance day-to-day convenience and enjoyment.
In 2023 and beyond, Echo Dot 4 represents the new gold standard for affordable Alexa integration. Consider grabbing one for the kitchen, bedroom or office to fully experience hands-free control over music, smart devices and everyday information via your reliable voice assistant.
