The BS1 is a noble first effort from Penon, it’s refinement is especially impressive given that some vastly larger and more experienced manufacturers can’t pull off the earbud form factor. Several small tweaks over the original Tomahawk make a world of difference in daily usage; the BS1 is a comfortable, very well constructed and refined sounding earbud at a very affordable price. I’m a particular fan of their revised housings and vastly improved cable which is easily one of the best I’ve handled around this price. I also admire Penon’s subdued styling choices which reflect similarly upon their more refined acoustic tuning. So while they do have some bass spill and perhaps an overly laid-back high-end back for some, for just $40 USD, Penon provide a stunning soundstage, fantastic bass definition and a super natural, analogue tonality.
Verdict – 8/10, The BS1 provides all day comfort, exceptional build and comfort combined with a smooth, natural tone. It also offers a sizable performance upgrade over cheaper models and competes favourably to similarly priced models of differing form factor. The BS1 is a surprisingly well-rounded and versatile performer that addresses essentially all of the complaints we had from models before.
