Radius Atomic Bass (Black)


Colorful earbuds have become increasingly popular with headphone manufacturers, possibly due to consumer demand for something a bit more stylish than plain white or black. It's no wonder: earphones are basically accessories that serve to pipe music to...

The Radius Atomic Bass earphones feature a comfortable, compact, and stylish design. They're inexpensive and offer a ton of bass. Some songs sound great.

The Radius Atomic Bass earphones suffer from muffled, chaotic audio at times. The cable is thin, which means it's tangle-prone and may not be durable.

The Radius Atomic Bass earphones are a good choice for bass-addicts with an eye for style and a concern for budget.

Radius Atomic Bass Earphones for iPhone Review


For a while now I've been looking for an affordable replacement to my dying iPhone earbuds. I wanted a pair that had a built-in mic, as well as answer button, and of-course -it should have good sound quality without costing an arm and a leg. At home, I...

Clean range from lows to highs, stylish design with nice choice of colors, moderate sound isolation, solid controls with integrated answer/ipod control button

Some consumers may shy away from the design of the earphones as they go deeper into your canal

I have been using the Radius Atomic Bass for iPhone on a daily basis for almost two weeks and am very happy with them. It’s important to note, that the earphones are not only compatible with the iPhone and iPhone 3G, but they also work with the iPod...

"Overall good sound, but not durable."


Overall good sound quality with great bass, but they fell apart after a couple months. The ear cups always were falling off and I had to replace them often.

Great bass, good sound quality, fits well

Vocals a bit muffled at times, cable always was tangled, and they weren't durable.

"good sound, weak quality"


I got them for $20 on Amazon. They lasted a few months. If you're going to use them for working out, consider them to be disposable after a while. Otherwise, plan on taking pristine care of them.

good bass

skinny wire gets tangled easily

"Incredible headphones"


I like the product because they have TOP NOTCH sound quality (even better than my big headphones), are compact, the perfect length for ear-to-pants-pocket wiring, lightweight, different plug sizes..

Superb sound quality, extremely light and comfortable in ear, excellent noise cancellation.

Stick out a little too much for my taste

"Outstanding Sounds Quality!"


Contact Radius customer service at to receive a 35% military discount from their website! Thank you Radius!

I recommend these to anyone looking for a top quality in-ear headset. Radius sent 10 of my coworkers in Iraq a complimentary set to try out. We were extremely pleased with the sound quality.

Microphone headset doesn't work well with the IPOD touch/Skype. Not sure about compatability with Iphone but I was told that is what they were designed for.

"Bass is less than average."


I would not buy these again, I fail to see how Radius can market them as "Atomic Bass" when in my experience the bass production is the weakest aspect of the product.

Relatively comfortable, decent price, crisp highs and mid' "atomic bass". The bass is very thin. I compared them to some Ear Candy "Ink'd" ear buds; the Ear Candy buds (1/2 the price) had a TON more, boomier bass, Radius cleaner mids and highs.

See above; very thin bass.

"Great Bass and Affordable"


I purchased mine from the manufactures website , might get lucky and they might have a sale.

The bass and I got my earphones with a mic for my iPhone. An awesome addition to the "plain" atomic bass.

To be honest, I can't think of any for the price, its a great earphone.

"If you like bass, these earbuds should be your choice."


If you really like bass and reasonable mid and upper ranges, I don't think there is a better earbud for the money. The lifetime warranty is important because these like all earbuds will eventually fail, and it will probably be sooner rather than later....

Great bass. Several sizes ear inserts included. Lifetime warranty with very good customer support. My first pair shorted out after 4 months; Radius sent me a new pair quickly.

My first pair of Atomic Bass earbuds shorted out after just a few months. I use them for running, so maybe CNet's comment about the thin cord being not very durable is right.

"Great sound, cheap price, very sleek looking"


Great headphones. Got them as a gift, fits in my ear perfectly. Very cheap for its capabilities.

Great bass sound, not too much bass, has some noise canceling ability. Stays put, doesn't fall out when I'm working out.

Wire is too long gets tangled in clothing and jewelery
