## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great crisp sound Good fit
  

*by Z***A on Reviewed in the United States on June 14, 2018*

I bought these earphones for my morning workouts. They came with the middle sized "wingtip", but we switched it out for the smaller size. The medium size fit okay, but the smaller one was more comfortable. I thought that they might fall out if I changed  it to the smaller size, but they seemed to have fit like a glove. I could barely feel them and I never felt like they were going to fly out when I was jogging.I also really like the fact that you can hear the ambient sound around you. So if I was crossing the street or running next to the bike lane, I could kind of hear what was around me. It made me feel really safe. I also bought another model of earbuds from Sudio, but those ones really block out the sound. So I would probably prefer these when working out outside.Also the color is really nice!

### ⭐⭐ 







  
  
    Ridiculously overpriced, almost useless
  

*by A***R on Reviewed in the United States on May 23, 2018*

I got these to use as exercise headphones, having previously owned a pair of Sennheiser MM100s, which served me well for years. I switched to the Sudio buds hoping to find something similar to the Bose soundsport wired headphones, in particular the  StayHear tips that seem to beat everything else on the market.These left me entirely disappointed. On the plus side, the tips, while definitely inferior to the Bose Soundsport buds, stayed in fairly well while also allowing ambient sound through, a positive quality for headphones I wanted to use while running or biking. The sound quality is mediocre but not awful, and the battery life is decent.The big problem with the Sudio Tres are their terrible range. If you plan on using these while sitting stationary at a desk with your phone or other audio source within arm's reach and above your waistline with nothing in between, these will work just fine. If you plan on moving at all, putting your phone in your pocket, or moving your hand or arm between you and the phone on occasion, these will not. The audio begins to cut out once I get more than about 5 feet from my phone/audio device, if it's positioned otherwise optimally. If I'm carrying it with me, I have to hold the phone at about chest height on my right side in order for the sound to not cut out.With these limitations, these restrict my mobility more than wired headphones do, which kind of defeats the purpose of wireless bluetooth headphones altogether. I've experienced better reception with cheap $20 bluetooth buds from WalMart. The fact that these are priced as they are is frankly unbelievable. In the future, Sudio may do better to spend a little more on design and less on their needlessly robust packaging.
