By robustly analysing the many top conference phones on the market, we've been able to whittle down the daunting wealth of options to five of the best, listed above.

The speaker comes in a few different color options and has touch controls on the top along with LED lights that indicate whether you're connected via Bluetooth, on a call and whether your microphone is muted. You can also connect directly to your computer with the included USB-C cable -- the speaker charges via USB-C -- and a USB-C to USB-A adapter is included (you can store it in a slot in the base of the speaker, where you'll also find a threaded tripod mount). Battery life is rated at up to 20 hours, and a 10-minute charge gives you two hours of juice. The speaker is splash-proof and dust-resistant with an IP64 rating. I like how Jabra has redesigned the new models, giving them a sleeker, cleaner look, and all the models include an integrated USB-C cable with a USB-A adapter that allows you to plug the speaker directly into a Mac or Windows PC. The relatively compact Speak2 55 comes with a nice felt carrying case and is fairly lightweight, weighing in at 280 grams (9.88 ounces), making it easy to slip into a bag and carry around for conference calls on the go. While it offers Bluetooth 5.1 connectivity, it doesn't come with a USB Bluetooth dongle to plug into your PC for more reliable wireless connectivity with computers.The first thing to consider when choosing from this list of the best conference phones is the your business requirements. If your conference calls tend to only be populated by a handful of people in a single room, your needs will be more modest than businesses whose conference calls are held in bumper meeting rooms with tens of participants. Naturally, the latter will require a more sophisticated (and more expensive) option than the former, so make sure to also consider what budget you have available to spend when whittling down your choices. I played some music through the speaker and it sounds decent though not great for a compact Bluetooth speaker. As you might expect, it's strongest in the midrange, where vocals live, so it does well with acoustic music. We've also run the rule of battery life as well as portability, given that larger businesses in particular may be in the habit of changing conference call rooms frequently.

The built-in speaker provides excellent audio quality, and it can even be used to play music. Given the price, it is not as laden with additional features as some of the other best conference phones on this list, but its intuitive plug-and-play connectivity makes it easy to use in just seconds, and it's also among the most stylish around, too. As you might imagine, it is compatible with other Jabra headsets, though it's not a standalone unit, so it needs to be connected (either via a wire or Bluetooth) to a PC. For the price, though, this is an excellent choice. Lastly, consider other options and features that might prove useful. Would it be of any use if your conference phone could double as a speaker? Is it of benefit to ensure even tech newbies can use it, or is your business populated with IT-savvy workers who could handle a less intuitive but more advanced system? Would it help if the conference phone could record your meeting automatically? The speaker drivers remain the same as those in the previous model, but the Qualcomm chipset that powers the speaker has been upgraded (the speaker uses Bluetooth 5.1), bumping the sound quality up a tad, particularly at higher volumes, with better digital signal processing. It remains one of the best-sounding mini Bluetooth speakers, with richer more tonally balanced sound than other Bluetooth speakers its size -- and it should sound good, considering its elevated price point.. It's unclear if you need the dongle because the speaker has an integrated USB-A or -C cord to plug directly into a computer and charge the device, but the dongle makes for easier pairing.This has everything you want in a compact but portable speaker phone. Along with the USB-A connector, it has Bluetooth. A protective carrying case and lanyard are also included. There's also a USB out port for charging a phone. Battery life is rated at up to 20 hours.
