With a precise 4-way crossover, the Stardust delivers high-resolution sound with impressive clarity and a deep-diving, solid bass response. Unique Melody has featured specially developed 3D printed medical-grade titanium material ear shells. The stardust packs the look and feel of an intergalactic space element with its dynamic design. Unique Melody Stardusts is here to take you on an intergalactic journey of top-quality sound!!

Six Drivers Producing Magic:-

UM Stardust is equipped with a six-driver hybrid architecture featuring dual dynamic drivers and four balanced armature drivers. This combination creates the ultimate sonic harmony with a punchy lower end, crisp midrange, and detailed high-frequencies. The custom dual DD setup is precisely tuned to deliver a strong bass response, while the four BA drivers are precisely divided to produce delicate and defined mid-high frequency bands. The stardust delivers a warm, immersive sound with clean and detailed instruments.

Precisely Tuned With Four-Way Crossover System:-

Unique Melody has adjusted the tuning of Stardust with a seamless four-way frequency crossover system. It integrates the dual DD and quad BA architecture with precise adjustment for different frequency segments. We have a DD working for ultra-low frequencies, a DD for punchy mid-bass section, dual balanced armatures for crisp midrange, and dual balanced armatures for a defined high frequency segment.

3D Printed Titanium-Material Ear Shells:-

Unique Melody has crafted the ear shells for Stardust using aerospace-grade 3D printing technology. They have utilized titanium from powder materials through a high-temperature laser sintering process, which helps them create a unique hollow shell and a distinctive look for the pair. Titanium material is extremely light in weight, with an ergonomic shape, and the Stardust offers a comfortable wearing experience for the users.

Custom-Developed Stock Cable:-

Unique Melody Stardust comes with their own customized Tunewire cable that is specially developed for this set. It is made up of high-purity 5N long crystalline oxygen-free copper and 5N long crystalline silver-plated copper wire cores. Featuring Litz Type 4S braiding, the cable offers crisp sound signal transmission with minimal loss. It is available in 4.4mm, 2.5mm, and 3.5mm termination options.

Well-designed and quiet, but didn’t keep my dog interested
Color: Blue
My dog was interested in this at first, but she would lose interest after a few minutes and move on. I do like that it’s quieter than the hard plastic ball toys, and the charge lasts well. The internal charging port that twists closed is also a nice design feature. That said, it will occasionally turn on by itself, which can be a little surprising. Overall, it has some nice features, but it just didn’t keep my dog engaged.

Good - for a few hours
Color: Blue, Color: Blue
Concept is fantastic. Dog loved it. Problem is that she figured out how to open it within two hours of play. The robot core, alas, did not survive. In the photo, you see a tooth went cleanly into the button and that was the end of the toy.

The most engaging interactive toy for my Border Collie
Color: Orange, Color: Orange
My Border Collie is not a big ball player. He prefers tug type games and actually gives me a look like, “Are you stupid? I’m not going to keep bringing that to you if all you’re going to do is throw it away again!” after about the third time I throw a ball for him to fetch. However, I can only play tug so often and I need him to be entertained and engaged as much as possible. I got him a smaller, non-padded ball like this hoping he would like the interactive aspect of it. He did- he actually loved it! But it was loud, hard on his teeth, would come apart periodically, and he kept hitting the off button when playing with it. It drove me crazy. This one is so much better overall! The soft outer shell is not only easier on his teeth, but it is super resilient to biting and chewing. He actually likes to carry this thing around in his mouth while it’s bouncing and vibrating. The three modes give great flexibility for different kinds of play. His favorite is the most active mode: the ball reacts to touch and practically bounces itself across the floor when he touches it with his paw or mouth. I will point out that in one of the modes, I thought the battery wasn’t charged or there was a motor issue because it’s very subdued movement; however, it’s just set up as a low-key option. Be sure to check out each mode to see which works best for your dog at different times. I can’t say enough about this ball- I have been so pleasantly surprised by how much he loves it. The rechargeable feature is super convenient, it’s big enough to not get stuck under the couch, and it automatically shuts off based on whichever mode it’s set on. As the owner of a busy, super-smart dog who needs to be engaged in mental and physical activity, I think this all is worth every penny. In fact, I’m buying one for a friend who has a Border Collie pup with lots of energy to burn! I highly recommend this toy- it’s the most engaging toy I’ve found that Finn will play with on his own.

Not as Smart or Interactive as You Think it Will Be
Color: Blue
This is an honest review from a schnauzer owner who has has wanted this cheerble ball for their dog for more than one year. I finally bougI finally bought this toy and both me and my dog are disappointed. The settings are...i would say dog friendly as I'd assumed a dog ball would be. What I mean by that is, for example: the calm play setting is muuch too calm. Super light puffs of energy, like a battery is dying. And the playful setting is scary, alarmingly so. The intervals in between are too long. The ball does not bounce. So they just have settings all wrong. The size is good for a large dog only. Do not buy if you have a small to medium dog. I even think the material is okay. I've only had it for a few days so I can't even speak to how the material holds up. Really hoping to love this ball for my dog. It was not the distraction I was hoping it would be so I could work from home while my dog had fun. I'm hoping this can help someone else who's been pining over it. Essentially, it's a $35-$50 well made weighted ball that moves occasionally.

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
