Initially the set-up for the FlowFonix Buddies was a little troublesome, but once I got the pairing mastered, it worked well.
The trick is that the left and right earphones need to be paired to each other before you attempt to pair them to your device. There is audible feedback to confirm the device has paired; however, the feedback does not specify whether you're pairing to the other earphone or to the device. The good news is that with a little practice, it becomes second nature to pair successfully.
There was a bit of an issue with connectivity after pairing which was rather distracting. The left earbud is the "master" which connects to the right, and then to your device. When walking and moving the device around only a little, the right earbud had a very intermittent connection problem. The sound would drop out and fade back in at random intervals. The left earphone did not have this problem, so I suspect the issue lay in the connection between the two earbuds. I tested out two sets of earphones and the problem existed in both.
I would describe the sound quality of these earphones to be acceptable but not exceptional, taking price into consideration. Overall I was happy with the quality, but when comparing with a higher end model, such as Shure 215 headphones, the difference was noticeable.
I tested the earphones with a variety of music, including Flume – Wall F**k for low frequencies, AC/DC's Back in Black for mid frequencies and Darude's Sandstorm for high frequencies. The low-frequency (bass) response was quite average and washed out. When the bass dropped on the song, the experience was disappointing. The mid and high frequencies were better; however, they were noticeably lacking full "colour" in the music. Apart from the lack of bass, the sound of most songs was acceptable.
For situations where convenience is key, such as commuting, they're ideal, but for longer term appreciation of music, you might be better served seeking out a better pair of headphones, even if you do have to eschew the wireless feature.
