Key Features of Bluetooth Helmet Speakers
How can you find the best Bluetooth helmet speakers? It’s a growing market so it can be tough to sort through all the brands, products, and features to choose wisely. While there is a wide range of features to take up here are some of the main ones:
That old saying “You get what you pay for” generally applies. If you buy a Bluetooth helmet speaker in the under-$20 price range, you shouldn’t expect a ton of bells & whistles. That said, it’s still important to think about the total value you’ll be getting. This is more important than the price point to make sure you’re getting more bang for your buck.
You should certainly set a budget. Make sure to stick to it since it’s just as important otherwise it sort of nullifies the whole concept of setting a budget, to begin with. Make sure to focus on how much you can afford to spend rather than how much you want to spend.
It’s also important to consider how a particular unit’s features will affect the price. What’s the maximum number of riders you’ll want in an intercom group? Do you want to multi-task by making phone calls and listening to music at the same time? Do you want the speakers to support Bluetooth 5.0?
These are some of the various factors that will affect the price point of the helmet speakers. You can also save money by shopping around, finding sales/discounts, and finding perks like free shipping through Amazon Prime. The bottom line is it’s better to focus on value rather than price. If you find Bluetooth speakers you want at a price you can afford, then it’s certainly a good situation to be in.
This is always important when picking a Bluetooth system, but it’s especially critical when using a Bluetooth headset/intercom system. When you’re riding your bike, it’s critical to cycle through the options as easy as possible.
The best option is one that includes a system of voice commands. This provides a hands-free way to make calls, play songs, and chat with riders. You can even find some units that let you interact with Apple’s personal assistant Siri after linking the Bluetooth speaker to your phone or tablet.
The next best option is one-button controls. This is also a simple yet effective way to cycle through the different options like Play/Pause/Track Forward/TrackBack, and so on. This system is 100% easier than dealing with a different button for each function, which isn’t practical when you’re riding.
An X-factor is the size of the button(s). One of the biggest complaints of some headset/intercom systems is the buttons are too small. When you’re cruising down a highway or country road, you won’t want to fiddle with small buttons.
If you pick a system over basic headphones/speakers, then this will include an intercom system. It allows you to communicate with people in your riding group that can range from 2 to over a dozen. Usually, only two people at a time can talk over the intercom system although there are some exceptions based on the tech used.
Another important factor related to the intercom is the maximum range for communicating with others in the riding group. This is a key issue especially during road trips when it’s common for riding group members to get spaced out due to various factors like traffic patterns.
It’s highly advisable to look for a Bluetooth helmet speaker that includes a warranty. Sometimes you can find comprehensive lifetime warranties, but it’s quite rare. Even if you get a limited warranty, it will add value to your purchase.
Make sure to read the terms & conditions to find out what is and isn’t included by the warranty. Usually, a limited warranty covers defects due to materials or manufacturing although it really depends on the company’s offering.
Then check how long the warranty is valid until since the date of purchase. The most common durations are 1 or 2 years although you can also find longer warranties. Again, make sure to find out not only how long the warranty is valid but also what it covers.
Bluetooth speakers also are sometimes covered by a satisfaction guarantee. This usually allows you to get a refund within 30/60/90 days of the purchase although sometimes you can only exchange the unit for a new one.
A money-back guarantee usually shows a company wants to provide top-notch customer service.
Sena and UCLEAR are among the best-known brands in the niche of Bluetooth helmet speakers. The formal Bluetooth specs were released about two decades ago in 1998, so it’s a relatively new technology. However, sales of wireless speakers including Bluetooth units have been spiking in recent years. This is due to various factors including improving tech and consumers not wanting to deal with a bird’s nest of wires.
Since Bluetooth speakers for helmets are less common than other Bluetooth speakers, it’s advisable to do some research about different brands you see at online retailers like Amazon. Make sure to research issues like the company’s history, social presence, customer reviews, etc. This will give you a general sense about whether the brand is one you should consider or avoid like the plague.
You should definitely watch out for generic, off, and “fake” brands. If you buy speakers from these brands, you can save tons of money, but you’ll likely have to deal with other issues. That includes ones like product quality and customer service.
Saving some money on cheap helmet speakers isn’t really worth it if it means you could end up with a world of problems. For example, if the speakers break quickly, you might have problems returning the units or even contacting the manufacturer. The end result would be money down the drain.
More specifically, does the particular system you’re considering have it? This is important because it could cause issues if others in your riding group own Bluetooth speaker gear that’s incompatible with yours. Make sure to consider options like Sena since they use a universal intercom protocol. While you technically could ask people in your riding group to buy new intercom gear for your next road trip they might not be too keen to do that. It’s better to go with a universal protocol.
You can use helmet speakers to enjoy your favorite tunes in different ways. You can play favorite playlists on a media player. Another option is to connect your speakers to your phone then stream music through Spotify, Pandora, etc. You can even share music with other riders through the intercom system. Music is easily one of the best ways to make your road trips less humdrum. Tech advancements in areas like music streaming have made it easier than ever to take your favorite playlist with you on the road.
Many companies offer this feature, but the technologies and quality can vary a lot. Highways and byways can be loud places, so it’s important for you to hear as clearly as possible when you make/take a phone call or chat with another rider. Look for intuitive systems that automatically make tweaks for incoming/outgoing audio. How do you know if a noise control system actually works? There’s no way to 100% sure until you actually test it.
So it’s a good idea to read some reviews based on Amazon’s Verified Purchase. This will usually give you some honest feedback about issues like the effectiveness of noise control systems. High-end systems will have steeper price tags so make sure to factor that in when doing price comparisons.
Lithium-ion batteries are often used for Bluetooth speakers based on the various benefits they provide. When picking a particular speaker unit, you should research the quality/capacity of the battery. As always make sure you bring at least one spare with you since “stuff” happens in life and especially with batteries.
Then you should also check the battery’s specs. How long does it take to juice up fully? How many hours of talk time, music playback, and standby time will you get on a single charge? These figures differ from unit to unit but can be a major factor when you’ll be motorcycling all day.
Bluetooth was developed in the mid-80s but has only been commercially available since 1998. The latest version is Bluetooth 5.0, which was launched in late 2016. As with other tech upgrades you can find solid Bluetooth speakers for motorcycle helmets that don’t support the latest version. Yes, in one sense Bluetooth 5.0 has the clearest audio versus past versions.
That said, there are other factors that affect the audio quality of Bluetooth speakers. They include the materials, design, and craftsmanship. Even the amount of interference blocking a Bluetooth signal can affect how clearly you can stream music or chat with your buddy.
Is water-resistance an important feature?
Can the headset's volume affect the durability?
What range is usually needed?
It depends on factors like where you'll be riding. Ranges can range from 400m to 2km. There are various factors like whether you're riding in an open area or through a city/woodland, weather conditions like rain/snow, etc. If you stay within the above-mentioned range, you shouldn't have any problems using your Bluetooth helmet headset. You should also consider higher-end units since they'll have higher ranges.
What range is usually needed?
Make sure to have the headset inspected from time to time and check for damage. Note that since the headphones are often built into the helmet, the process will be tougher. So it's a good idea to consult a professional to do the inspection for you.
It's one of the main reasons you should consider standalone headphones instead of built-in units. In fact, it will also be easier to remove the unit and inspect it yourself versus helmet/speaker combos. Plus you can still use the headset for non-riding applications, so there's also that.
Can Bluetooth waves be harmful?
In a word: no. The waves are actually weaker than for an average cellphone. Another factor is headsets are located outside the helmet, which creates a buffer between your ears and the sound waves. You might have heard that Bluetooth waves are dangerous in smartphones. That's simply an untruth myth. The Bluetooth waves are safe and cause no harmful rays, radiation, etc. That's also true when using the wireless tech to listen to music, take calls, or get GPs info while riding with your best Bluetooth helmet speakers.
