GUIDERAY has released the GR-V5, a 5 BA driver IEM, which, according to the budget model GR-i, belongs to the middle class and costs about 170€.

All new, all exciting... Nope!

The V5 is nothing different than the MAGAOSI K5 re-released. How do I know that? For one thing, I rely on my hearing, of course. On the other hand, I recently started measuring my IEMs as well. But I would say that this is not very representative for the outside world, because I don't use ear simulation couplers, but have made something up myself. But it helps me to check the channel equality and to find out gross errors in the frequency response, but also to compare in-ears with each other. See there, the frequency response of the V5 and K5 is identical, so my hearing is not wrong.

Consequence: the sound analysis is identical to the K5, so you shouldn't expect any new mental effusions, also the handling is quite similar, but read it yourself.


>> Slowly I am getting tired of reporting on the wearing comfort of individual in-ears. Either I have a universal ear, or I am largely insensitive to it. Or else, we have been more or less spoiled for some years now, by universal IEMs, which wear like Customs (assuming the correct tip is chosen). The latter applies 100% to the K5. There's absolutely nothing to complain about here.

As tips I use the foam tips (no foam) of the Audiosense T300, which form a perfect symbiosis here, despite the thicker sound tubes compared to the T300. But the tips of the T300 are flexible enough. <<

Enough about K5... uh, I mean V5. There are still differences. The V5 uses a 2-pin connector instead of MMCX and has a slightly narrower and rounder faceplate. But the fit to the ear and the sound openings are identical. You can also see the identical drivers and their arrangement through the transparent resin.

The biggest difference is the packaging design. In contrast to the K5, we still get an imitation leather case, but we have to do without the Bluetooth cable ( there is worse). The choice of tips, which includes double flange tips, is identical.

Finally, a short side trip to the K5:

>> The case is completely closed, which guarantees a perfect isolation inside and outside. When I close the sound opening with my fingers, there is almost nothing to hear, even at dangerously high volumes. <


Extract from the K5 review:

>> As with so many IEMs that emphasize the middles more than usual, it takes a short time to get used to the signature.

A typical BA bass. Fast, dry, clean with good control. The midrange bass is more pronounced with a fast roll-off in the sub range. This is however present, although not completely satisfying. It doesn't stand out very much, but harmonizes extremely well with the mids without overlapping them.

The K5 focuses its attention on the midrange and this is where it can shine the most. The mids are smooth, clear and convince with excellent transparency and separation. In general, the K5 is perfectly suited for voice-heavy music, as they impress with natural timbre and are not preferred by either man or woman. With their focus they create an emotional intimacy and build the instrumental arrangement around the vocals. The upper mids give the sound a slight hardness and effervescence without getting hot.

The trebles have a moderate extension and manage to open up the sound by the slight boost in the upper trebles. In general, everything that enters the stage plays more in height and depth. The width of the stage is a little less pronounced in comparison, but the K5 manages to split the music into several layers. Otherwise, the treble can be somewhat unnaturally metallic in rare cases, but on the whole, a very safe tuning was taken care of here, which makes the K5 very audible in the long run. However, the certain something is missing and also some details are swallowed, or require more concentration. <<

If someone really comes across a difference in sound compared to the K5, then first of all respect and secondly it can at most be due to a different material of the sound tubes inside, or the cable. At least subjectively I can't find any noteworthy one and objectively the frequency response doesn't let me find one either, except a little bit of scribbling beyond the 10kHz mark.


The V5 is not a new IEM, but a very good one.
Whether you decide on the equally expensive MAGAOSI K5 or the GUIDERAY GR-V5, the only question is whether you prefer a 2-pin connector or MMCX.
The rest is irrelevant and maybe colour/optics is a matter of taste.

With its safety-conscious tuning, great vocals and very good isolation, the V5, like the K5, is perfectly suited for stage use as a vocal IEM. But for the musical everyday life it is not the first choice for me.




Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.

Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
