Review: Balanced Beats - I ordered the matte black version and really liked the finish, color, and overall appearance. The headphones fold up nicely and come with a compact case that fits easily in my gym bag. I bought these to replace my original Solos and was hoping for the same bass-heavy sound. The sound quality is very good, but it’s more balanced than the original model. The design feels durable, and the passive noise isolation works well enough that I didn’t miss having ANC. Battery life was also excellent. Ultimately, I returned them because I mainly listen to hip-hop and EDM and prefer a stronger bass response. That said, these are great headphones and would be a solid choice for anyone who enjoys a more balanced sound.

The black and gold design looks stylish and premium, and they connect easily with both Apple and Android devices. Overall, these are great headphones with excellent quality for this price good material

### ⭐⭐⭐⭐⭐ Fits tight. Finding it hard to wear after 20min.
*by J***M on March 31, 2025*

Over a year later update: I’m glad I kept these. They have been the most reliable headphones I have. I can always count on a connection, amazing sound quality, and no ear ache from wearing them long term. While I initially didn’t like how they felt on my ears, they’ve since softened and really cup my ears well. I changed my two star rating to a five star because even though there was “break in” time, they are consistently my go to and the reliability functions BEAT out any other competition (even the fruit named buds). Many months later update: I decided to keep them. They’re not my favorite headphones but they do well enough. I like using them at the grocery store but they’re still subpar in my book. I’ve been losing weight (unrelated to the purchase of this), and it is healing with the fit but they still don’t feel good in my ears. The ear pad just is too small. The battery is awesome though. I need to charge them about once a month. Overall, still would not recommend without testing them on your head before you buy. Good luck 👍 Update: after a week, I don’t like these. They are far too small and push my ears to my skull after 10-15 minutes of use. I’ve down rated these from 5 stars to 2. The ear pads are not condusive to an adults ear shape. I’m not a petit person but I also am not overly large. I’m actually typically fair in the middle on most occasions… but these ear pads are downright awful. They are not squishy enough when the pressure of the headband wrap the device around my ears, nor are they big enough to cover my ear. So they end up pressing firmly down on the top tip of my ear or the outer edge, leaving me with incredibly sore ears after just a few songs. I’ve taken them to loud places, like planet fitness where they blast their own rage music, and honestly, I had to boost the levels of audio on my headphones to compete… it’s just not worth the money. For $20-$30 more, I could just get the apple pro pods that have even better reviews… I originally got these because I’ll be flying more with my job and wanted something that didn’t go in the ear but also get comfortable enough for long flights… this ain’t it. Which sucks because this is my 7th(?) pair of headphones I’ve tried and had to send back? I don’t know what I need to do right now and I’m not sure if I am going to return these simply because I’m tired of this process. I’m tired of hoping and praying and waiting and experiencing let down after let down. The charge seems fine enough but honestly, I haven’t been able to wear these long enough to test how long the charge is. The connectivity seems fine. I connected them to my iPad and iPhone XR just fine. The buttons work and connecting to the audio port was nice but definitely drained my device battery faster than if it was Bluetooth… Anyway… if I keep them, I’ll come back and update again if things change. If I return, at least you know what you’re in for. Original: So far so good. Will give these a good trial run and report any findings back. I did just get these out of the box and they do fit tight but I’m on the larger side too. Time will tell if I can wear my glasses or for prolonged periods. Sound seems good. Not Noise canceling.
