REVIEW – So here we go again. One of the most exciting testing series for me has been the earbud challenge and that battlefield where I enlist all earbuds to try out for the top spot. It is the battle to see which pair can be the best of the best for me and my personal taste. While individually subjective, it continues to be a great way to compare the various brands and what they offer. Now the Phiaton Bolt BT 700 Wireless Bluetooth Earbuds have entered the competition. Let’s see how they perform.

What is it?

The Phiaton Bolt BT 700 Wireless Bluetooth Earbuds are like most earbuds that handle audio listening as well as phone call functions. These earbuds feature Balanced Armature Drivers and a charging case that includes a built-in speaker.

What’s in the box

1 x Pair of Phiaton Earbuds
1 x Charging Case
1 x Micro USB Cable
4 x Pairs of Ear Tips
1 x Instruction Manual
1 x Warranty Leaflet

The Phiaton earbuds are not tiny but not large either. They come in a charging case that is approximately 3 1/2″ x 1 1/2″ x 1 1/.2″. The left side of the case is longer than the right because there is a  speaker that is housed in the left side.

On the right side, there is a Bluetooth button, 4 blue led lights for charging status and remaining charge, and the micro USB charging port.

On the other side of the charging case, there is a built-in speaker.

In terms of music, these earbuds fit comfortably in my ears, and they function quite well. They have a nice volume range that works for me for all of my favorite genres, with a maximum volume that does not overwhelm and will not cause any damage to my hearing. The lows, mids, and highs are good and without distortion, but if you want to experience the lows in their full capability, it is very important to use the correct size and properly fitting ear tips.

For phone calls, these earbuds work ok even for someone like me that has had issues with all of the earbuds that I have tested except for one set. These are decently clear for both parties as long as I raise the volume of my voice just a bit for the other party to hear me clearly.

The earbuds automatically pair with the Bluetooth connection when removed from the charging case, and the connection is consistently solid and did not once disconnect involuntarily. These earbuds like most others have voice commands that confirm the connectivity. You should keep in mind that because there is a speaker built into the case and because it also operates via Bluetooth, the earbuds do not automatically disconnect when returned to their respective place in the charging case. A standard function of earbuds is to disconnect when placed in the case and the charging contacts are engaged. With these earbuds, I can place them in the case, close the case and they will not disconnect until you press the Bluetooth button on the side of the case to disconnect them, or you disconnect via your phone settings. Otherwise, and as I experienced, when you receive a phone call, you are unable to hear the other party on the line until you realize that the earbuds you put away a while ago are still connected.

In terms of the built-in speaker, it sounds surprisingly pleasant albeit closer to a full range sound as opposed to the earbud sound that provides the easily recognizable separation of lows, mids, and highs.

What I like

  • The build quality
  • The sound
  • The comfortable fit

What can be improved

  • The ability to disconnect the Bluetooth connection when the earbuds are placed in the case without having to press the case button to power off/disconnect.
  • The manual is in such fine print that it is almost impossible to read

Final thoughts

The Phiaton earbuds do a great job with sound for all of the genres I tested including, jazz, R&B, Easy Listening, Reggae, Gospel. etc. They are well built and quite comfortable. They stay securely in my ears irrespective of any vigorous head movements, The only issue that bothers me is that they do not disconnect the Bluetooth connection when placed into the charging case. I quite understand the intended logic behind this design, but I would prefer them to automatically disconnect and I would re-engage them should I want to use the speaker that is built into the case. Since this is a challenge for the best of the best for me (my taste), this feature takes them out of the race for first place. If this issue does not bother you,  these would be a great buy and they still get two thumbs up!!
