great for on the go, one time use

The sound of speaker is loud enough in my room. As I know from their website, this brand has its own line audio product. Therefore, I bought this speaker. After test, the sound is good enough in this price for me.
Also, I usually go hiking and I will bring this speaker. It is a little bit heavier than I expected. But it is alright if I hook it on my backpack. I love these earphones. The sound and build quality is superb compared to the cost of less than $65.00. The sound is crystal clear and really sparkles when listening to good recordings. These earphones have a pretty flat response that really deliver what the artist and recording engineers intended you to hear. As others have mentioned, this is not a set of earphones for a true bass head. The bass is punchy and solid when it needs to be but it doesn't overtake the overall sound. If heavy non stop bass is your cup of tea then you may need to look elsewhere. This product definitely qualifies as more of a 'studio monitor' earphone when compared with many of the other earphones on the market. The Heaven II is certainly a model you'll want to add to your collection if quality sound reproduction is important to you. With expedited shipping they were delivered in 7 days. I am an extremely happy customer of both the very high quality product and the prompt delivery service. A double win in my book. I discovered Final Audio Design while doing research on my most recent set of earphones and I'll certainly keep them in mind for any future purchases as well.
