I got fed up with regular Bluetooth speakers, so I'm using one shaped like a sci-fi Martian robot instead — here's why you should too

If you were to stack all the best Bluetooth speakers together in one big pile, you'd very quickly realise that they all look very similar. Some are tubes of different colors, some are boxes with handles, and some are supposed to look like amplifiers from classic rock brands. If you're anything like me, that can mean things feel a little boring.
Well, along came Gravastar and this ridiculous thing. It's the Mars Pro, a mono Bluetooth speaker which is designed to look like a robot war machine thing from, I presume, Mars, and I love every single thing about it. I think you might too.,
Despite its bizarre styling, the Gravastar Mars Pro is actually a really good Bluetooth speaker. Its mono sound is powerful, and if you get two, you can connect them together for extra stereo sound. It's not the cheapest, but those looks have to count for something, right?
I'd hesitate to call it a work of art, but the Gravastar Mars Pro brings the fun unlike just about any other Bluetooth speaker. It's a weird ball thing on mechanical legs, covered with bits and greeblies likes something from a budget sci-fi film in the 90s. Is it up everyone's street? Almost certainly not. I can't imagine there are millions of people clamoring for a Martian walker from War of the Worlds that plays Britney at top volume, but there are some. And I am one.
Those legs are articulated to some degree, so you can kind of pose the speaker. For the most part, it's going to be fairly static, though. It's a statement piece, something that draws the eye of visitors and makes them ask, "What on earth is that thing in the corner of your room, and why does its eye thing follow me around the room — please turn it around."
Everything is topped off by those RGB lights. I'd say this is the first time I've seen a Bluetooth speaker where I've appreciated the lights. Generally, they feel a bit like a gimmick — they're never going to actually power a party. Here they're an accent to increase the Sci-Fi looks, and I'm a massive fan.
My mom was not — one look at the speaker and she asked me to put it back in the box. And, like every person who is still 13 years old at heart, I simply moved it closer.
It's also built like a tank. There's metal in them there legs, and the whole thing feels reassuringly hefty. It goes some way to justifying that slightly loftier price.
"Oooh, stereo this, stereo that..." I'm guilty of it — if it's not at least two channels, I don't want to know. Except I found that when listening to the Gravastar Mars Pro, I didn't really care. It sounds excellent, not just for a weird Bluetooth speaker with a single audio channel, but for a Bluetooth speaker in general.
That "plays audio out of the front, glowing eye" thing does mean that the audio is fairly directional. You have to be sitting in front of the speaker for it to sound its best, but given you're unlikely to make it face the wall (unless your guest demands it), you're generally going to be in the cone of sonic influence.
And when you are, you're in for a bit of a treat. I'd never call it 'HiFi' — it's not, and it's not intended to be. But it is big, loud, and very much in charge. There's some decent detail to proceedings, good mid-range representation, and then some fairly powerful bass that we're fed through the passive bass radiator on the back.
Fit for an Autopsy's The Sea of Tragic Beasts brings the slam, and the little bass radiator on the back of the Mars Pro gets moving. That characteristic sub-tone from the band is very well represented, shaking the table the speaker sits on. The drums are impactful and full, while the crunchy guitar distortion shows plenty of edge to keep things heavy.
The cymbals can get a little lost amongst the rest of the din, but for a small speaker, things are very tasty indeed. Loads of fun.
Given it's style, there's no way you can't try out The Eve of the War from Jeff Wayne's Musical Version Of The War of the Worlds. Those string swells are deep and wide, giving plenty of presense. The synth line is well seperated from the rest of the ensemble, while the shaker cuts through. Richard Burton's dulcet tones rumble, as the Martians launch their way to Earth. I presume they look something like this speaker.
What lots of speaker manufacturers forget is that audio is supposed to be fun. Making everything into austere grey boxes or colored tubes that look like every other waterproof speaker around isn't fun. Making your speaker look like a three-legged death machine that's going to melt down your mom to feed the alien war machine is fun.
And that's something that Gravastar seem to have gotten so right with the Mars Pro. It sounds good yes, and it's very well made, but it's the sense of fun that the speaker exudes that sets it apart from just about everything else. I spent a good hour posing various different action figures with the speaker before I'd even started listening to music — and I think that speaks volumes.

My favorite Bluetooth speaker just crashed to its lowest ever price — the EarFun UBoom L is just $49 right now

When I'm using one of the best Bluetooth speakers, nothing makes me happier than feeling the bass in my jaw or in my temples. I want earth-shattering bass that makes me concerned for the walls in my rental. I want it to be so rich that I feel like it's calling me poor. I want it to feel deeper than the pseudo-feelings I had as a Tumblr emo girlie. My poetic musings aside... I love testing wireless speakers and putting them through their paces to determine whether they're good value for money. I have a couple speakers at home but the one I (and my partner) use the most is the EarFun UBoom L — and right now, it's down to its lowest ever price as it's discounted by 38% at Amazon U.S. and 13% at Amazon U.K. The EarFun UBoom L offers big sound on a budget. This portable speaker produces powerful bass, clear vocals and well-balanced sound across a range of genres. With a dedicated outdoor mode and an IP67 resistance rating, the speaker can soundtrack pool parties and hikes, it's got great battery life, and the customizable EQ via the user-friendly companion app works really well. Even at its retail price of $79 / £79, the UBoom L easily warrants a recommendation. It provides big sound on a budget, and it's highly portable so you can take it anywhere you like. Adding to that is the UBoom L's IP67 rating, which means it's waterproof down to 3 feet and fully dustproof. Trust me, I use this speaker in the shower nearly everyday, and I've even submerged it in a sink full of water just to show off to my friends — and it has always come out unscathed. Now, onto the sound quality... Utilizing the brand's "JumboBass technology," the UBoom L delivers powerful bass thanks to its passive bass radiators on each side working in conjunction with the 55mm drivers. When you play a bass-heavy track, you can see the side radiators vibrate and, like I mentioned up top, you can feel the bass in your soul (depending on how far you are from the speaker, of course). Residents of the rainy British isles will be pleased to hear that the EarFun UBoom L is discounted here too... although not by much. It's down to £69 from its retail price of £79 but even though you aren't saving as much as the Americans, it's still worth the investment. One thing I really like about this speaker as that basslines never feel overpowering. They have an oomph with a lovely warmth to them, so you can really appreciate each note that the bassist is plucking. Even at high volumes, music remains free of distortion, making the UBoom L the ideal speaker for soundtracking social gatherings. Vocals sound just as good, if not better, and there's plenty of detail in every track to be enjoyed and appreciate. I often hook it up to my laptop too when I'm watching a horror or thriller movie, and the speaker creates an eerie soundscape. For a small, portable speaker, I'm always taken aback by how powerful the UBoom L sounds. If you want a rugged speaker that doesn't cut any corners, I'd recommend saving $30 at Amazon U.S. or £10 at Amazon U.K. You can thank me later.

Bag These Sennheiser Wireless Sport Earbuds for Just $75, a Whopping 50% Off

We firmly believe that a good pair of headphones or earbuds can be essential, especially if you want to listen to audio without bothering those around you. But if you're looking for sport headphones, you need something built for the task. The Sennheiser Consumer Audio Sport true wireless earbuds are a great option thanks to their combination of great features and comfortable design. They'd normally run for around $150, but you can grab a pair with a huge 50% discount today, dropping the price to $75. While you still have almost two weeks to place your order before this deal ends, there's one caveat to consider. Woot's stocks often run dry before its deals' end dates, so ordering soon is still recommended if you want to lock this special price in. Hey, did you know? CNET Deals texts are free, easy and save you money. These Sennheiser Consumer Audio Sport true wireless earbuds are Bluetooth in-ear headphones. Your purchase comes with the earbuds, a charging case (with a lanyard), a USB-C charging wire, closed and open ear adapter sets in three sizes and even ear fins sets. This ensures the earbuds will be super comfortable since you can adjust the fins and adapter sets to what fits your ear best. As for features, these earbuds are rated IP54, which protects against dust and water. So, if you're sweating while using them, they'll still work fine. They have a battery life of up to 27 hours, giving you all-day usage. They have a frequency range from 5 Hz to 21 kHz, meaning you can hear low subs and soaring vocals. Phone calls can be heard pretty well, too. Why this deal matters These Sennheiser earbuds have dropped to a new all-time low price. Previously, the record low price was $80, but that was last seen about a year ago on Amazon. Currently on Amazon, these earbuds are full price at $150. Woot has the lowest price on the market for these Sennheiser earbuds right now. But as you know, deals on Woot don't last very long. This deal is set to expire in 12 days, but if quantities sell out, it could be even sooner.
