There is no doubt about it, the Westone UM1s are a great pair of earphones for the price. With an estimated retail price of only $109 these headphones are well suited to take on the competition in this price segment. Their balanced warm sound signature will be appealing to the majority of listeners.
The UM1's bass performance is on par with most of the in-ears in its price tier and with a good midrange they are well worth the price of about $109. Considering the superb comfort and good cable solution the Westone UM1s are the best bang for the buck in-ear solution I have ever had the pleasure of listening to. That being said it is not as good as the more expensive UM2s in almost all aspects.
If I had to buy a pair of in-ears and only had around $100 to play around with I would not hesitate to buy the Westone UM1s. To me they resemble the best combination of performance, comfort, and fit. Because of the superb comfort and good performance I would actually take these earphones over some of the more expensive competitors.
