The Blue Baby Bottle is an absolute gem.
The Blue Baby Bottle is an absolute gem. The sound is rich, warm, and detailed—perfect for vocals, acoustic instruments, and even voiceovers. It brings a professional polish to anything I record. It’s become one of my go-to choices in the mic locker—reliable, versatile, and always delivers a clean, balanced tone. Build quality is solid too. Easily one of the best investments I’ve made for my studio.

economical but professional microphones
These are well made, economical but professional microphones. Low noise floor and good output. They also look cool.

Beyond expectations
Originally, I had attempted to cancel the order to get the cheaper version but was late to the punch. Ended up being a blessing in disguise as the microphone quality sounds amazing.I had an old Blue Spark microphone from back in 2011 and it broke while I was moving place to place over the past few years. This microphone was far better quality which I didn't know I was missing until I used this one. Very clear and crisp sound, capturing only what I need it too and not all the extra crap in the background.They say this one has an almost vintage sound to it, but with my current effects rack, I can't be sure. All I know is it's got some class to it and I'm so glad I got it. I had been away from music for 3 years and since purchasing this, I've been recording week to week on a regular basis. Definitely happy with this and would highly recommend it to anyone looking to up their quality of their vocal performance.

Does what it needs to
Good darker sounding condenser mic. My only complaint is that the switches feel extremely cheap. Everything else on the mic feels high quality. The mic is also very heavy.I’ve recorded saxophone and voice on it so far. For alto sax, it sounds great. Very clear and the high ends are not piercing. Soprano sax sounds okay on it. I would need to do more work with that to dial in a better sound. I’m sure it works well for all woodwinds, I would just experiment with placement.For male voice, it’s good. I would recommend speaking or singing at an angle and with a pop filter because it can be a bit boomy up close. With good mic technique and eq, it’s fantastic.

A good vocal mic, BUT ! ...
Like most Blue mics, it's dead quiet and focused on a purpose. This is vocals. It's got a strong mid, upper mid and good treble, but it's not bright, not neutral either. Cardiod, but not wide. NOW ! Mine is a refurb. The label does not read "Baby Bottle" ! It has NO model ! ? unlike all other BabyBottle mics ever made. Is this a brilliant fake ? I may buy another.

Almost As Good As the OG Baby Bottle
I had one of the OG Baby Bottle microphones before Blue had been sold, I believe my mic was made in Latvia at that time. I ended up trading that mic many years ago because I didn't love it on my vocals, but in going back to some of my old recordings, I realized that I REALLY loved that mic on acoustic guitar (pro tip, when recording label the mic name on your audio files in your DAW, i.e. Acoustic_Guitar_Blue-Baby-Bottle.wav). I bought this on sale and it's definitely very close to what the Blue Baby Bottle sounded like on those previous recordings. It's a bit bright for vocals, so I would use it slightly off-axis, but it might be the perfect fit for certain singers. I think a pair could work nicely for drum overheads depending on what type of SPL's you are looking at from the drums.For those of you in 2025 that are still unsure what type of mic can interface directly with your computer, this is an XLR microphone that requires an XLR mic cable to a microphone preamp with 48V phantom power to work. An audio interface like the Focusrite Scarlett is the link to your computer through USB, the mic would plugin to the XLR port on the Scarlett which would provide phantom power and gain. If you're looking for a mic that would plugin directly to your computer and just work, look at something like the Blue Yeti USB or Shure MV7, peace.

Sounds expensive, and feels high quality
It makes my voice sound so good it’s crazy, upgraded from a $180 mic to this one, and the difference was night and day to me. This mic does a really good job at defining your voice, a lot of your voice’s uniqueness shines through, and it’s sounds super crisp. When gaming people compliment my voice and I’ve even had some ask if I’m using a soundboard, I got it on sale but I still would’ve considered it at its original. The mic itself feels very sturdy and luxurious, has a nice weight to it to, and the shock mount it comes with is a 10/10.
