The very first impressions you get when you unbox this microphone are kind of classical. The way they have made it feels special with the wooden box. The wooden storage box for the microphone feels royal and professional as well.

The classy idea of the wooden storage box is something that I loved the most.


Obviously, that’s what you have bought. You get this amazing Blue Spark SL Microphone wrapped inside the wooden storage box.

That is nice. You get the shock mount with 5 – 8 inches adapter. Having a shock mount makes a lot of our work easy. It does help to reduce the vibrations and the noise on the desk as well. Everyone must get the shock mount for their microphones. Blue is giving it to you, that’s a good deal.

Build Quality

The design of this microphone is pretty nice. This design is specific for the Blue microphones. You might get confused with the Blue Spark SL and Bluebird microphone.

The first impressions on this microphone are pretty amazing and you will love it.

There is also the black version called “blackout” is available of this microphone. I will prefer black over red, always!

Metal body

Spark SL has an all-metal body. It has also got the metal grill in the microphone which makes it more durable and reliable as well.

That makes this microphone a bit heavier as well. Although it weighs 336 g and it has 220.5mm x 45mm of dimensions.

Specifications of Blue Spark SL

There are so many inbuilt specifications available in this microphone to make it versatile. All the technical specifications help make this microphone much better in a different way. All the specs are far better with the ideal benchmarks.

Blue Spark SL microphone is the large-diaphragm studio condenser microphone. It brings much more options while recording.

Spark SL has the cardioid pickup polar pattern which captures the sound perfectly without losing any details and without having any noise. Cardioid polar pattern records all the audio from the front side only to avoid the noise and produces ambient output.

Frequency Response of this microphone is 20Hz to 20KHz, which is ideal for every studio condenser microphone. You can capture almost all types of sounds being the right high and low range pitches as well.

The sensitivity of this microphone is -29 dB which is quite decent and makes it more natural to some sounds.

It has got the output impedance of – 50 Ohms, and the maximum sound pressure level (Max SPL) is 136dB. Which mean you use it for some high-end instruments, but you can’t use it for the acoustic guitars or drums. It will work very fine on the electric guitars.

The noise level of this microphone is 16.4dB-A which is perfect for noise cancellation. Signal to Noise ratio is 73dB-A of this microphone which is also very decent.

Spark SL is the studio condenser microphone, and that is why you will need the external power requirement of about 48 ohms. You can use the phantom power supply to use this microphone.

Experience with the microphone

Blue Spark SL is fantastic at the look even better at the sound. You are going to love this microphone if you are going to use it for your studio. I have made the list of 5 Best Studio Microphones Under $100 in 2021. Spark SL can’t be on that list because of the pricing. I would have picked spark SL over all of them for the studio recordings.

Spark SL feels like an entry-level condenser microphone if you compare it with the Blue Yeti. In terms of the usage, it is a much more versatile microphone.

I will suggest you use the pop filter while using this microphone to filter out the best input. I will recommend using the pop filter in almost all the mics you will get.

Spark SL is the condenser microphone, and it captures some of the ambient noises in your studio. Thus, this mic will also do the same. If you do have a quiet environment (studiolike), then there is nothing to worry about at all.

For the electric guitars, it sounds charming. The sound has the aggressions which boosts the sound wherever needed. The low end does not overpower, or it does not become muddy like other microphones.

For acoustic guitars, this microphone does not fit at all. I won’t recommend this microphone for acoustics. The sounds seem to bit distracted in acoustics.

For the singing and vocals, this microphone does the best job. You must have checked the vocal samples of this microphone above. They sound very nice. Air boost and the body of the sound is pretty accurate

-100Hz of high pass filter helps make sound smooth and natural. This gives the best feel for the audio output in the microphone.

For spoken words and recording, this microphone will do decent work. For multiple users, this is not recommended. If you are using it for the podcasts or gaming, then this will do the charms.

For the professional uses, I will tell you to go for the Blue Yeti over Spark SL. But for the stuff like podcasting, gaming or streaming, Spark SL can be your best pick.
