To power on the earbuds you have to take them off from the charging case and place it in the ears. Follow by pressing the two top most buttons. Each button are multi-functions but you can probably master it within 5 minutes. The passive sound isolation is good thanks to the long sound tube length that goes deep into the ear canal.

The Treblab X5 is powered by a pair of 8.2mm Beryllium Dynamic Drivers. It should be noted that Beryllium driver are very rare to find in the market due to high cost and it is a miracle that this is available in a sport wireless IEM like this. The Beryllium is stiffer (for the strength diaphragm) and it doesn’t produce unwanted vibration that cause audio distortion at any frequency. Furthermore, it is highly responsive when it comes to reaction time (thickness of diaphragm). Treblab X5 uses Bluetooth 4.2 for connectivity and it has a maximum stable line of sight connection up to 11 meter.

AUDIO QUALITY

POP/EDM:
Tiaan – Be Ok (Low bass frequency)
The low bass frequency is superbly energetic and notable, and you can feel the air pressure booming in your ears. It doesn’t eat into the vocals and has zero bass distortion. The subtle bass vibration fades smoothly and the low bass frequency is well bodied. The low bass does slightly overpower the vocals just a tiny bit.

Pia Mia – Do It Again (Standard bass)
The bass is highly energetic and firm, you can feel the air pressure booming. You can feel the bass fades butter-smooth with a long drag especially at the 2:05 mark. The vibrations is just pure eargasm and one of the best in our reviews. The bass does slightly overpower the vocals, and there is a clear separation between the two. The bass is well bodied and EDM tones sounds fun and exciting.

Vocals/Instrumentals:
Violinder – Raindrops (Instrumental)
The piano/violin tone sounds right and natural. It leans closer to the crystal-clear type not the warm-sounding type, I personally prefer the crystal clear type. It has the right amount of shine at the high frequency. Tonse are well bodied and doesn’t sound half-hearted. The bass/drums feels balance with the piano/violin in term of audible levels. Sometime the piano/violin does sounds slightly notable and there is clear separation between the two. A good indication of a balanced IEM.

Pentatonix – See Through (High Pitch Vocals / Group Separation 5th volume)
Mitch Grassi’s high-pitched-male Tenor vocals perform really well at the high frequency with the right amount of shine and it feels bright. One of the best we have heard on a true wireless earbuds. Each singer can be identified easily, every diction and pronunciation is crystal clear. The vocal beatboxing, echoing, humming is just eargasm and the best part it does not overpower Mitch Grassi’s vocal in the song.

FINAL VERDICT

Calvinpixels.com | Calvin Pixels | Treblab X5 Review | Beryllium Sport True Wireless Earbuds

It is not easy to find a Sports True Wireless Earbuds that performs well throughout the range from the low frequency to the high frequency. A great improvement from the Treblab X11 that we review in the past and can closely rival to the Sony Wireless IEM like the Sony WI-SP600N and Sony WF-SP700N. Personally, I don’t mind a slightly larger charging case if they can bump up the battery capacity to keep the battery life longer. On the last note the Beryllium gave this X5 an edge to outmatch most of it competitors out there.         Calvinpixels.com | Calvin Pixels | Treblab X5 Review | Beryllium Sport True Wireless Earbuds
