Shure SM58 Vs PG58 Comparison

If you are looking for a reliable dynamic microphone, you certainly have heard about Shure SM58 quite some. It is the cult classic, has been trusted by many beginners and experts on the field since a long time ago. However, there is also Shure PG58 available over the market, which is priced quite more affordably. So, how does Shure PG58 compare to Shure SM58? Which is the model that you should get?


In terms of design, Shure SM58 and Shure PG58 are somewhat similar. Shure SM58 comes with an off-black color and is a little bit slimmer, while Shure PG58 comes with a darker black color and a little bit bulkier. They each has a silver metallic grille that is very rugged and durable, ready for heavy-duty usage. The cheaper Shure PG58 comes with a dynamic cartridge that features a simple but rugged coil, allowing it to handle extreme volume levels without any distortion. However, Shure SM58 comes with a more complex internal design. It features a pneumatic shock-mount system that cuts down most handling noise, and a built-in spherical wind and pop filter. It is also supplied with a break-resistant stand adapter that is rotatable up to 180 degrees for easy and versatile mounting.  FYI, Shure SM58 Vs SM57.

Both microphones are also cardioid, which means that they pick up sounds the best from the front. The pick-up angle is somewhat wide, extending slightly to the sides, while attenuating the rear. Such design allows the mic to minimize background noise and feedback, and to focus on the main sound source.

In general, Shure PG58 is similar to Shure SM58. These mics perform an excellent job in capturing vocals with decent clarity and crisp. Tuned specifically for vocals, the midrange is brightened and there is some bass roll-off to embolden the vocal presence. However, Shure PG58 indeed comes with a narrower frequency response range and a lower sensitivity. Shure PG58 is also more prone to mechanical vibrations. On the other hand, Shure SM58 boasts a decent frequency response range of 50 Hz – 15 kHz. Hence, you can notice that Shure SM58 delivers more power into the reproduced audio. The sounds are also more properly staged and defined. In addition, the integrated spherical filter also helps a lot in eliminating the proximity effect and minimizing low-frequency noise such as wind and breath sounds.

Both Shure PG58 and Shure SM58 are available in several variants. You can get either mic without any cable if you already have your own XLR cable to work with. If not, Shure PG58 can be purchased along with an XLR-to-XLR or XLR-to-1/4” cable. Shure SM58 can be bought with an XLR-to-XLR or XLR-to-USB cable. They each also has a variant with an on/off switch included.

Shure SM58 Vs PG58

- Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect
- Effective built-in spherical wind and pop filter. Frequency response: 50 to 15,000 Hz
- Pneumatic shock-mount system cuts down handling noise
- Tailored frequency response is smooth and extended. Tuned specifically for vocal applications
- Cardioid polar pattern picks up the most sound from in front of the microphone and some sound from the sides
