Guide to the Best Bluetooth Auxiliary Adapters

Not all Bluetooth adapters are created equal. Depending on what you’re trying to do, grabbing just any adapter can quickly put your entire audio setup in a perilous space. Great adapters take advantage of the latest advancements in Bluetooth technology. With that comes a higher sound quality you’ll appreciate when listening to music, and the clear and intelligible sound you want for a phone call. A great adapter should be as easy to set up as plugging it in and pressing a button.

But bad adapters exist as well. If you don’t choose carefully, then you’ll end up chained to a 10-foot range, find yourself shuffling around dime-sized batteries, or have your device break after a few weeks of light use. Choose an adapter suited for a car while you’re in your home, you’ll be buying features you don’t need and passing up features that could have helped you.

Knowing What to Expect from Your Bluetooth Adapter

If you’ve got an auxiliary-audio input jack, then you have everything you need to add a quality Bluetooth connection to your devices. Whether it’s a car, a CD player, or your home stereo, Bluetooth auxiliary adapters can help you add wireless to your favorite devices without having to replace everything you own in the process. As long as you have an audio-in port, you’ll be able to modernize your old stuff with the cutting edge advances to Bluetooth.

The least an adapter can do for you is save you from the clutter and tangle of wires, and prevent you from bleeding out your sound quality in the process. The least it can do for you is help you connect to your headphones, speakers, car, and other devices. The least it can provide is convenience, helping you seamlessly transition from playing sound from your speakers to a Bluetooth headset, so you don’t bother anyone around you. You should expect more than that from your Bluetooth adapter, especially if you know precisely what you intend to use them for.

For example, if you want to add Bluetooth to your car, then features like noise and echo cancellation will be a must. They’ll improve how well your voice can get through a call, even if you’re in a convertible with the top down. And if you share a vehicle and need several devices to connect to the adapter, you’ll want to be on the lookout for support for multiple devices.

Making Quick Evaluations with Bluetooth Profiles

You’ll also notice adapters list the Bluetooth profiles that they support. For example, hands-free profile (HFP) and headset profile (HSP) are what handle phone interactions. Advanced audio distribution profile (A2DP) handles audio distribution from device to device. And A/V remote control profile (ACRCP) enables remote control over a Bluetooth connection, usually for features like rewinding, fast forwarding, and so on. For the most part, you can ignore these exhaustive list of acronyms. But if you’re not exactly sure what features are supported by the device, these initials are a useful way to quickly check.

Getting What You Pay For

Another sticking point is the range of connection. Your natural impulse is probably to go for an adapter with the greatest possible range, but that’s actually a mistake. When it comes to quality Bluetooth adapters, get the features you pay for. When you’re buying an adapter that lets you stand an entire football field away from your car during a call, you end up paying for that feature. That means if you don’t find yourself trying to make Bluetooth calls 100 feet from your car that often, then you don’t want to pay for special features you’re not using.

At the same time, you don’t want to end up restricted to something as feeble as a 10 foot connection. Short connections are quickly rendered useless if all of your devices aren’t perfectly arranged to accommodate the Bluetooth signal. A general happy-point between those two extremes is around 30 meters. That’s enough distance to give you breathing room around your car, and it works just as well in the largest rooms of your home.
