M4U TWM True Wireless Micro Planar Earphones

COMING SOON

Uncover the pinnacle of portable, hi-definition listening with PSB’s next-generation TWM True Wireless Micro Planar Earphones. Bleeding edge Magneto-Static technology in a Hybrid Planar dual driver design work together to deliver smooth, studio-quality sound in a remarkably compact earbud design. Extended battery life lets you listen for up to 8 hours with an additional 24 hours of charge stored in its smart charging case. Built-in technologies including aptX™ Adaptive Bluetooth, Audiodo™, RoomFeel™ and more create the most customized, audiophile-grade listening experience.

  • Premium True Wireless Micro Planar Earphones
  • aptX™ Adaptive HD Bluetooth connectivity
  • Custom sound calibration with Audiodo™
  • Natural and open RoomFeel™ tuning
  • Leverages Magneto-Static technology

Superior Sound, Perfected for You

The TWM leverages powerful Magneto-Static technology in a Hybrid Planar dual driver design which reproduces sound with minimal distortion, crisp highs, natural midrange and deep, lush bass. Dedicated transducers, one for high frequencies and one for low frequencies work together to make the whole mix sound truly pristine. The high frequency Magneto-Static driver utilizes a thin, low mass diaphragm driven in a static magnetic field to move the diaphragm at ultra-high speeds with minimal distortion for crisp, clear, ultra-high resolution sound reproduction, even at low volume levels. The dynamic planar midrange/bass driver combines deep, fast bass and rich, natural midrange with a wide soundstage. The result of this Hybrid Planar design is destined to be pure music to your ears.

While most earbuds assume that your hearing is consistent on both ears, the reality is the opposite – no two ears hear in the same way. Accessed through the PSB Headphones App, a custom hearing test by Audiodo Personal Sound™ analyzes your left and right ear separately and maps out a precise understanding of your unique hearing. The latest implementation of Audiodo includes a Volume Dependent Compensation feature so the TWM can accurately match the timbral balance of the music at any volume level you choose. In addition, there are four EQ presets you can engage for specific music or movies – tighter bass, more detail, better dialogue and the default preset – RoomFeel™.

Signature RoomFeel™ Tuning

Created to deliver rich and natural sound through headphones, the next generation of PSB’s proprietary RoomFeel™ technology mimics the experience of listening to a pair of high-quality, full-range speakers properly set up in a good room. Carefully developed, using research and expertise around ‘Room Gain’ – the energy and warmth that room boundaries add to the response curve of a flat-measuring loudspeaker, RoomFeel makes the music feel less ‘in your head’ by recreating an open and in-room listening experience through the M4U TWM. Whether you’re moving through a busy street, catching transportation or at the gym, RoomFeel brings you the most non-fatiguing and natural sound possible.

Active and Adaptive

Using adaptive technologies, the M4U TWM headphones adjust to your environment while you move, work and play. Pair the headphones to your device seamlessly with aptX™ Adaptive Bluetooth, a 24-bit, HD universal Bluetooth technology that uses a variable bitrate to enable low-latency audio reproduction for playing games or watching movies while still offering the best possible sound quality. Whether you’re at home or outside while taking a voice call, cVc™ (clear voice capture) technology suppresses any background or ambient noise around you, so you still transmit crystal-clear voice quality no matter what environment you’re in.

Easy, Extended Listening

Hard click buttons on both earphones make volume control, skipping tracks, and voice calls easy and intuitive. The smart charging case with auto-pairing offers both wired USB-C and wireless charging options. Enjoy 8 hours of playback time and an additional 24 hours of charge stored in its accompanying case.

Included with the earphones are 3 sizes of comfortable silicon tips to provide excellent noise isolation and an in-ear fit that stays put, even if you’re moving. The earbuds are IP65 rated, making them sweatproof, water resistant, dustproof and well-suited for any active endeavor be it the gym, cycling, running or a long commute.

The full featured PSB Headphones App turns your device into a remote control for your M4U TWMs, giving you access to specific sound settings and features that you can adjust for a richer listening experience. With the tap of a few buttons you can create a sound profile using Audiodo, control noise transparency levels, choose from preset EQ settings, check battery level and more.

Doesn't really taste like bacon. I know becaused I chewed it. Great as a slower eating thingy.
Style: Dental Chew, Flavor Name: REAL Bacon, Size: Dental Medium
So my dog has this thing where she does not want to chew on anything that she is supposed to chew on unless it's a knuckle bone that she cannot be trusted with (because she bites off fragments of bone) or one of those flexible, edible nylabones for "gentle" chewers, which she will eat in a single sitting. If I want to get her to chew something that might actually withstand her for more than an hour, I have to pretend it's mine. It's a secret forbidden treat that I love very much and just "accidentally" left within her reach to steal and covet. So it's pretty much standard practice at this point that, when I get her a new chew toy, I gotta carry it around for a while, pretending to chew on it. I got this bone in the mail and did exactly that, but I noticed right off the bat that, for a bacon-flavored thing, it didn't smell like anything at all. It was just this plain sort of plastic scent. And that's how I ended up actually chewing on it instead of just miming it out because maybe the bacon flavor was under the initial layer? But no, it wasn't. It was just bacon-colored plastic. So if your dog is the type of chewer that will chew regardless of flavor, this should work out fine. If not, go for something else. My dog did not give a heck about this bone, even once the "this is actually mine but you cleverly stole it away" ritual was completed. After that, I tried putting it in her bowl with her food, thinking maybe the flavor of the food would rub off enough that she'd want to chew it. She didn't, but what did happen is the reason I'm giving this a positive review at all. While it fails utterly as a chew, it makes a really great impromptu "stop eating so fast, you tornado shaped like a dog" mechanism. We've bought actual slower eating bowls for her and never had any success, because she just gives up and cries if she can't get her face into the crevices. But when we put this in her regular round bowl and pour her wet food around it, she's able to nose the benebone around in the bowl as she eats her food, but it does slow her down considerably. She's way less farty and whiny after food time, which anyone who has experienced how specifically racid dog farts can be will know is a blessing. So, thanks, Benebone. For us, your product is worthless as a chew, but invaluable as a makeshift slower eating thingy. Edit: Benebone got in contact with me about my review and offered to refund my purchase and send me some different products to try. I declined the refund, because I do find the bone I bought useful for the above-described purpose of slowing my dog down when she eats. But I did accept the samples. She's still pretty unimpressed with them, and I will probably end up passing them along to other dog-havers I know, but I myself am pretty impressed with Benebone's customer service and so have changed my review from 3 stars to 4. It was "suggested" that I mention that other dogs will probably be more satisfied with Benebone's flavors if they are not as picky as my dog is, and that sampling a Benebone yourself is maybe not the most reliable way to test its tastiness, when dogs have much more sensitive noses/tongues than humans. Which is certainly true! But I don't think my dog is a complete alien for wanting something with slightly more discernible flavor and scent. And I do think some of the advertising for Benebone implies more of that than you actually get in the finished product. So I'm gonna have to double down on my previous assessment that, if your dog likes to chew for the sake of chewing, Benebone will probably really appeal to them. But if they're a more food-motivated chewer, you're better off with fully-edible chews like rawhide or bully sticks.

My Dog’s Favorite – Durable & Keeps Them Busy
Style: Fishbone, Flavor Name: REAL Jack Salmon, Size: Small
This is my dog’s favorite chew by far. I used to go through chew toys constantly and could easily be replacing them every week, but this one actually holds up. It keeps my dog engaged and gives me peace of mind knowing it’s something they enjoy and I can trust in terms of durability. If you have a dog that goes through toys quickly, this is definitely worth trying.

My Pitbull absolutely loves the bacon flavor.
Style: Stick, Flavor Name: REAL Bacon, Size: Medium
This is officially my dog’s new favorite toy. She plays and chews on this thing nonstop. She has dozens of toys and she doesn’t touch any of them unless, she forgets where she left her bacon stick. This is a must for the perfect Dental Toy. I kinda suspected she’d love these things, so I also bought the knob in chicken flavor. She likes the chicken but, it’s so obvious she loves the bacon flavor. Smart girl. I absolutely love bacon also, bacon is perfect by itself, and it makes everything else much better. Except a bacon martini, so disgusting. The main reason I bought two was to put one in my vehicle, for road trips. My dog is my child, my Princess, so she goes almost everywhere with me. I knew this would be great for keeping her entertained and distracted while we’re out running errands and stuff. I always keep separate toys in the cars for her to chew on. A few years ago I forgot to grab a few toys out of the bin and she decided that boredom was a good excuse to chew on a seatbelt, no cool. Ever since then I decided to have dedicated toys that stay in the vehicles, so I’ll never forget again. The toys she loves the most are the ones I buy multiples of. One for the house and one for each vehicle. For me it’s simpler. I did notice at first, her gums did bleed a tiny bit. She’s a Pitbull, very aggressive chewer but, only with certain toys. This is definitely one of those toys. The bleeding stopped after a few days and things are back to normal. This is truly a unique product. I call it a toy but it has many positive perks. It’s her favorite. She plays with it all the time. Any time I need to distract her for something I grab the Benebone and show it to her, she immediately gets excited and self soothes. I feel like dental hygiene is the biggest bonus of all though. I’d say 80% of her toys have dental hygiene in mind, that’s very important to me, along with not having bad breath. She see’s a flavored toy, and I see her getting dental praises at every vet visit. All parties are extremely happy. This toy is also extremely durable. With that said, I knew she wouldn’t be able to chew through it overnight, or even in a week. It’s tough finding toys that she won’t chew through overnight. This product is lasting her a long while. It’s not always about the price. To me, a toy lasting more than a few months is more important than the money spent. Based on the video ad I saw online I knew it’d be a durable product, plus I love supporting happy families that bring something different, and unique to market. Happy family equals happy products. Once it arrived and I could feel the material and texture in my hands I knew for sure “no way she’s gonna chew through this fast, or maybe not at all”. Even though it really is lasting for a long time, I still feel like she’s chewing through it faster than other dogs. That’s just my particular dog. I had a tough time picking the right size for my dog. My Pitbull is small, about 35lbs. But man does she chew in the 100lbs + size range. I really wanted the biggest size for her but, I thought I don’t want it so big she won’t be able to even chew on it, or even just getting her jaws around it. So I went with ONE SIZE ABOVE the size/weight chart that is provided in the description, and it turned out to be perfect for her. It’s small enough she can chew and have fun. It’s too big for her to bite chunks off. In the past she’s bitten chunks off all her small toys. I put both the chicken and bacon in front of her to see which one she’d grab first. Of course it was the bacon. Then it took them both and put them in her toy bin to see which she’d grab. Again the bacon right away. I love bacon too, great choice thinking like me. So I the bacon flavor stays in the house, and the chicken I put in my car for road trips. The noises my dog makes while chewing and playing with this thing drives my wife nuts. It doesn’t bother me at all, not even a little. Thanks to multiple tours to Iraq, I can completely ignore petty noises and sounds. My wife on the other hand, will tell her to play in a different room. She listens and goes into a different room. That applies to both us for all of our dog’s toys, not just this one. To be honest these Benebones do have kind of a hard texturized plastic feel to them, so yes it does make a tiny bit of noise when she’s playing and chewing. I can almost promise and guarantee that any every dog will love the Benebone in any of the shapes, sizes, and flavors. It really is the perfect toy for a dog. Especially for aggressive chewers like my Pitbull, Princess Polly. She keeps her favorite toys in her bed. This Benebone has a spot beside her big squeaky tennis ball, rubber tug-a-war, and her deer antler. I haven’t even seen her touch the other toys since I bought the Benebone. I am extremely happy with my purchase and will for sure be buying more forever. I recommend buying multiple for inside your home and for each vehicle. You will not be disappointed, unless you buy one and your dog looses it and forgets where they hid it for later.

🐾Ridiculous aggressive chewer🐶
Style: Stick, Flavor Name: REAL Bacon, Size: Medium
Sooooo happy I finally found something that my moms pup couldn't chew up! Not going to like its been very tough. She has now for at least a week (sorry days pushing together 🤪) Let's just say the pup is a chihuahua mix that LOVES to chew. Emphasis on the chewing youre lucky if a toy lasts more than a day let alone a week 🤣 This is so durable I may not need one for her for a while but this will come HIGHLY recommended for ridiculously aggressive chewers. Suitable for ang size dog just make sure you go one size bigger then you think you should. Quick easy chew toys but definitely has some weight to it.
