Review: Acceptable Battery Life - Some reviews that I read before buying the DB-30 questioned longevity of the battery. Today is my first battery change after two and a half months of daily usage. The battery didn't die, per se; the metronome just started responding oddly to some input. A new battery fixed that. Longer battery life is always a plus, but I am fully satisfied with that of the DB-30. I also like the metronome very much because of its size, ease of use and overall quality.

## Questions & Answers

**Q: Does this "click"  or "beep" to indicate tempo?**
A: There are four tones.type 1 (clockwork metronome sound), type 2 (electronic metronome sound) type 3 (child clicking sound), type4 (Human Voice)

**Q: can you control volume?**
A: yes you can control volume, but volume is louder with earphones on and not very loud through its speaker...so it is not the best for me as a drummer...

**Q: Can you connect an AC adapter to this?**
A: No, the only external port is a 1/8" audio jack for headphones. You need to just buy extra batteries (CR2032). They last around six months for me with light daily use.

**Q: What is the beats per minute range?  Does it go down to 30?**
A: The BPM range goes from 30-250.  Hope this helps!

### ⭐⭐⭐⭐⭐ Best Metronome for the money
*by D***R on December 26, 2019*

I am a professional organist and use a metronome on a daily basis. I have gone thru at least 9 different metronomes in the past 10 years. The KLIQ was nice until it lost its mind before the year was up. I own a few Korg TM-50 units and they are real good, but they are a little too quite for my purpose (pipe organs are loud). This is the first time I have tried any of the Boss metronomes and was very immediately impressed with the functionality of it. If there was a higher grading than 5 I would have given this more than five stars. What I like about the Boss DB-60: Ease of use. I love the actual sound, it is more of a old wooden tock instead of a digital ping. I can instantly add or change half beats or third beats on the fly and give them different volumes. There is nothing to like about this DB-60, and if and when it breaks ( I am very hard on equipment) I will buy another Boss DB-60. I have finally found a metronome I really like after 50 years in the business.
