Samson CO3 Review – Budget Recording Studio Microphone

We put the Samson CO3 budget condenser microphone to test and reviewed the microphone. In this review, we compare the sound of the Samson CO3 to a more expensive mic, the Rode NT1-A.

The Samson CO3 Condenser Microphone

USD185 (at time of writing)

The Samson Co3 is a budget condenser microphone aimed towards beginners in recording. The microphone has an XLR connection, where you would usually plug it into an audio interface or pre-amp. The Samson CO3 also has a USB version, called the Samson CO3U (U stands for USB). 

I’d recommend the USB version, CO3U to people who wants simplicity and probably going to work with light recording work. The problem with a USB condenser microphone is that you’ll face expansion problems. With a USB mic, you’re stuck with having to use it with a computer. You can’t just plug the microphone into a mixer. So if you prefer to stay versatile and use your microphone across a few types of setup, post-production or live, go for the XLR version.


Unboxing the Samson CO3

The Samson CO3 comes with a carrying case

The Samson CO3 came in a simple carry case. I, still prefer a simple carrying pouch that is usually supplied by other microphone manufacturers.

The CO3 comes with the microphone itself and a microphone clip that is used to mount the microphone on a stand. The microphone clip is a very basic one that is used by being screwed on the bottom of the mic. In my experience using a few of these plastic clips, they often break after a few uses, so you want to be really careful with it.

Optional: If you prefer a better microphone clip, you can consider getting the SP01 spider shock mount that is designed to mount Samson condenser microphones and add isolation from bumps and mechanical noise from the stand that is holding the microphone.

Samson CO3 Features

There are some nice features on the Samson CO3 condenser microphone that make it a worthy contender among many other budget condenser microphones.

First, it has a low cut switch (hi-pass filter) which is used to eliminate and low frequencies when recording. The low cut filter rolls off at 12dB per octave at 100Hz. This is extremely useful for removing low frequencies such as lows from drums when you’re using the microphone as a snare or overhead mic or can be used to filter out low rumbles.

Second, the CO3 also has a PAD switch built in which is used to lower the input sensitivity of the microphone. I hardly find myself using this in my everyday recording process, however, this can be useful when you’re trying to record very loud sounds with high SPL (Sound Pressure Level), such as a drum kick or a trumpet.

And third, the neatest feature of the Samson CO3 is that it has a switch to select different polar patterns for recording.  It has a dual 19mm mic capsule built in, together with a switchable pattern selection. This gives you the microphone the ability to record with different pickup patterns from super cardioid, Omni-directional and figure-8 patterns.

These patterns can be very useful when handling different types of recording setups, like recording a vocal duet, guitar, piano, drum or even a group recording, like a choir.

Super Cardioid

This will probably be the pickup pattern that you most often will use in the studio. The super cardioid pickup pattern is designed to reject sound from the side. This is great for recording vocals or instruments when you want better separation of instruments in the studio. You can also use this pickup pattern in a live performance setup and control where the microphone picks up the sound source.


Think of the omnidirectional pickup pattern as an ‘O’. The microphone will pick up sound source from all directions. This is used when you want to record ambient sound or a natural reverb from a room.

I normally use the omni-directional when recording ensembles and groups. A cool trick is also to use the omni-directional pickup pattern when recording a vocalist who likes to move around the mic. This way, you won’t lose the volume of the vocalist as you would if you were using the super-cardioid pickup pattern.

Figure 8

The figure 8 pickup pattern picks up sound in an 8-figure – from the front and back of the microphone. It’s like having two microphones being placed front and back, but only that this is still a single microphone.

The figure 8 is useful for recording a duet between to artists, laying down a background vocal track or recording a podcast of two persons.

Cool recording trick: The figure-8 pattern can be used to creatively record a slap-back echo effect where you the front of the microphone records the sound source immediately and the back of the microphone records the bounce of the sound source from the walls, thus creating a slap-back echo effect. Experiment with the Samson CO3’s pickup patterns and you’ll find all sorts of creative recording placement you could use with it.

Samson Co3 Sound Recording Test


At the end of the day, it’s the sound of the microphone that matters, so we put the Samson CO3 microphone into a recording comparison test between the Rode NT1-A, an industry level reputable recording studio microphone.

We recorded both the microphones directly through the Komplete Audio 6 audio interface which has pretty neutral sounding pre-amps.

Watch the video above to hear the sound recording.

The Samson CO3 sound

When recorded side by side another microphone, you can really hear the sound difference. Compared the Rode NT1-A, the Samson CO3 sounds slightly muddier in the bottom end. It also lacks a bit of brightness & sparkle on the high end.

On the positive side, the Samson CO3 does have a full-bodied and warm sound. The sound rejection from the sides is also pretty good and the noise floor is also pretty low.

The Samson CO3 would be good for light commercial voice over projects and also for vocal recordings. On a guitar, the Samson CO3 may sound a little dull, due to the slight lack of the brightness, but that can be fixed with some clever mic placements and EQ-ing.


Would the Samson CO3 make the top list as the ultimate budget recording studio microphone? I think so.

If I had to choose between the many condenser microphones at this price, I’d go for the Samson CO3.

The Samson CO3 would be a perfect condenser microphone for beginners in recording as it has a lot of options of miking and you could almost use the microphone in any recording situations in the studio, ultimately making it a great tool to learn and understand miking techniques.

It’s also pretty inexpensive for the sound you can get from it. Granted, you won’t be making Hollywood sounding recordings with it, but it will get you far as a start. Besides, with some clever editing & plugins, you can actually make the recording from the Samson CO3 sound really good.
