Stay away, product does not work with app

Great for professionals, good case Cons Sound terrible, Sennheiser app does not pair with CX 400BT, very low volume, no bass, connection takes 2 minutes with headphones out of the Taken case, bought headphones, so I use the equalizer and the app, but every time searching for the device cannot find the Sennheiser CX 400BT. Not worth $199 I'm buying JBL Live 300 Sound 100% better sorry Sennheiser. But not too many connection issues for me, especially the headphones not working with the app. The…

Pros
  • Finally bought it
Cons

Disappointing product

I have several pairs of these wireless headphones, which are very good sound for $. I saw them for sale and decided to give them a try as they are considered to be some of the best sounding headphones out there. I was excited when they arrived, but it didn't take long for that excitement to fade. These were some of the worst sounding headphones I've tried, including several that cost well under a dollar. I decided to leave them on for a while to see if the sound would improve with the burn, but

Pros
  • Long battery life (20 hours) and comfortable to wear: up to 20 hours of music playback on a single charge - Ergonomic design offers optimal comfort and secure fit with 4 sizes of ear adapters
Cons
  • Appearance

Very very very good

I was hesitant to buy another one buy Sennheiser because there was no bass, although everything else is perfect. The sound here is perfect. Plenty (even overwhelming bass) if you ask for it in the app, and amazing Sennheiser detail throughout the rest of the spectrum. That's all you get. Amazing sound. They should cost around $150 considering the lack of features compared to competitors in this price range. ANC is meaningless marketing, but information (transparency) had to be in it. If you're…

Pros
  • Included components: CX 400BT True Wireless, charging case, USB-C charging cable, silicone ear adapter sets (sizes XS/S/M/L)
Cons
  • A long time ago

Bad unboxing but happy ending

I usually don't write reviews after using a product for less than 2 hours but these buds won me over. Out of the box they didn't sound the way I expected them to. Especially after all the positive reviews. At first it looked like my JBLs would outperform these in terms of sound quality, but they just needed time to break in. The firmware update was inconvenient both in time to lock up and to tether the phone (I couldn't use it to work with another headphone). At this point, I was hoping that…

Pros
  • Easy to use
Cons
  • Functionality

Great sound, battery life, secure fit, comfortable, no noise canceling

Being pointless; They should be decent headphones for this price. The headphones I will be comparing are the Apple AirPods Pro (hereinafter referred to as "Air"), the Sennheiser CX 400BT (hereinafter referred to as "CX"), and the Sennheiser Momentum True Wireless 2 (hereinafter referred to as "MO"). We continue. *Sound* All 3 sound great, but the MO was the clear winner, delivering the most realistic sound, including all the subtle highs and lows. The air wasn't a second too wide; it lacked…

Pros
  • Great for a small home
Cons
  • Unreliable
