Nearly three years ago, I asked if the (then) $429 Dyson Supersonic was still worth the price of entry.

These days, with the Supersonic line having expanded, the standard model having increased in price to $449.99, and the most expensive version of the hair dryer topping out at $549.99, it's a question that feels even more apt.

The good news? If you're not super into the idea of spending about $500 for a hair dryer, Dyson just announced the Dyson Supersonic Travel, a $299.99 model of its famous hair tool. In addition to its lower price point, it comes with more travel-friendly proportions and features.

As someone who's personally tested Supersonics (and their many dupes), I took a closer look at the latest Dyson beauty launch to gather everything you need to know.

The design differences of the Dyson Supersonic Travel

In short, the Supersonic Travel is the standard Supersonic but smaller. According to Dyson, that comes out to exactly 32 percent smaller and 25 percent lighter than the OG Supersonic. In other words, it's 0.7 pounds to the standard Supersonic's 1.8 pounds, and 8.7 inches tall to the larger model's 10 inches.

This model also comes with one attachment, the styling concentrator, a la the now-discontinued Dyson Supersonic Origin (which ran for $399.99). For comparison, the $449.99 Supersonic comes with three attachments: a styling concentrator, diffuser, and wide-tooth comb. For all five attachments, you'll have to shell out $549.99.

The same attachments can be used between the Travel, original, and Supersonic Nural dryers. This means opting for the Travel could technically save you some money — individual attachments range from $19.99 to $44.99. If you only use a styling concentrator and diffuser, for instance, the total cost of a Travel dryer with the extra attachment purchase would come out to $344.98, making it still over $100 cheaper than the three-attachment original Supersonic.

The Supersonic Travel is more versatile in some ways, and less so in others

Functionality-wise, the Supersonic Travel is a slightly different product from the other Supersonics in the line. It has anywhere from 1,000 to 1,220 watts of power and an airflow speed of 11.6 liters per second, compared to the 1,600 watts and 13.3 liters per second of the standard Supersonic. In other words, the bigger dryer is slightly more powerful, so it wouldn't be unreasonable to expect longer dry times.

The standard Supersonic and Supersonic Nural also feature four heats and three air speeds, where the Supersonic Travel features three heats and two air speeds.

That said, the Supersonic Travel has universal voltage compatibility, so it can be used from 100 to 240 volts, whereas the other Supersonics are locked into 120 volt compatibility.

In terms of its portability, it's also worth noting the Supersonic Travel weighs the same as the Supersonic r, a professional grade hair dryer (priced as such at $549.99) that's become more popular due in part to being lightweight and easy to maneuver.

Where to buy the Dyson Supersonic Travel

The Dyson Supersonic Travel is available for $299.99 at Dyson's website, Amazon, and Best Buy. If you buy at the former, you will receive a complimentary $59.99 travel bag along with the hair dryer.
