ProGuard P2+1 custom IEM summary (review in progress), discussion, and appreciation thread

ProGuard P2+1 CIEM discussion and appreciation thread with review in progress.

 

Review in Progress: ProGuard P2+1 custom IEM review: On stage

 

 

 

ProGuard Hearing Protection is a part of Sensorcom Ltd run by Rob and Richard (ex–Garwood, original manufacturer of IEM radio systems), both with around 25 years of audio and hearing protection experience.  The P2+1 was launched around 10 months ago, designed for the gigging musician.  They felt many CIEMs lacked good low end response which is how they ended up with the driver configuration of the P2+1, which is a dual low and single high driver.  They auditioned quite a few triple driver configurations, but for them this configuration worked and they thought the retail price point was right for a 3 driver system.

 

Designed for stage use, the P2+1 has some competition in the UK from a few other companies such as Minerva, ACS, and Puretone among others, but as far as I know, the P2+1 is has the lowest cost for a triple driver CIEM.  Since it is made primarily for musicians, the focus is performance vs. looks and artwork, and we shall see if these provide a good price/performance level.

 

How to Order & Options

The P2+1 is £300 ($467) without impressions and £320 ($500) with impressions (for UK customers only), plus customers in European Union pay an additional 20% tax.  Shipping charges are included.  The order process is started by placing an order online and paying via PayPal or credit card, registering your serial number, and then if you are in the UK, making an audiologist appointment.  You can find their audiologists here.  If you are outside the UK, you will need to send impressions in.

 

Options: Faceplate colors: black, beige, red, blue and translucent.

 

Warranty

The warranty period is 1 year and they keep your impressions on file for 2 years.

 

Design

The P2+1 uses dual balanced armature drivers for the low frequencies and single driver for 2K Hz and above.  The shell is acrylic with flush mounted jacks for a detachable cable. 

 

 

Specifications:

Frequency Response: 20 - 18000Hz

Impedance: 20Ω @ 1kHz nominal

Sensitivity: 120dB@1mW

Crossover: Passive @ 2kHz

Connector: 3.5 mm stereo jack plug

Cable: Detachable 1.5m - Kevlar Reinforced PU 2 Pin Gold Plated Earphone Connectors

Transducer: Dual LF Balanced Armature Driver + Single HF Balanced Armature Driver

Colour: Black, Beige, Red, Blue, White and Translucent

Delivery includes: Faux leather storage pouch, Cleaning Tool and Earmould fitting gel.

 

Accessories

 

Faux leather storage pouch, Cleaning Tool and Earmould fitting gel.  The carrying case is compact and easy to take anywhere, but doesn’t provide the crush-proof protection of a Pelican or Otterbox case.

 

 

Cable

 

The cable is detachable, 1.5m long, Kevlar reinforced cable with 2 pin gold plated earphone connectors.  The cable is silver but isn’t a typical twisted cable, but is a coated cable and is very supple.  The silver will not discolor over time and the ergonomics are good, much better than other cables I have tested of this type, and the memory effect is low.  This cable also seems a bit more durable than the standard twisted cables.

 

 

Isolation

Once inserted into the ear the P2+1 will give up to 25dB of sound.  The P2+1 scores a 5/10 on my scale, offering average isolation for a acrylic shelled CIEM.

 

 

Preliminary Sound Summary

The P2+1 has a stage monitor sound tuning, with a forward presentation that puts you on stage with the musicians.  The sound is a bit on the thicker side, which has been the case with just about every musician’s tuned IEM/CIEM I have heard.  Even with the thickness, there is a nice clarity in the midrange, however it isn’t as clear as the brighter sounding CIEMs such as the Ambient Monitors AM4 pro.  Bass is present and has good power and rumble, besting the other BA CIEMs I have heard in the price range (up to the $565 aud-5X).  The coherence across the frequency spectrum is excellent and imaging is quite good with good detailing for the price point.

 

The overall size is not small, but it isn’t the biggest, with more depth and height than width.  The upper midrange is forward, at least with higher end sources, which really accentuates details, but the thickness gives body and richness to the presentation so it doesn’t seem analytical.  While both male and female vocals sound true to tone for the most part, female vocals are rendered better and are quite good.

 

The P2+1 does OK with my Clip+, but from my iPhone 5 and higher impedance sources such as the Nova don’t sound great.  Moving up the amp ranks does pay dividends in improving the finer performance attributes of the P2+1.

 

Note: This sound summary is preliminary.  The sound summary may change, at least to an extent after I have done all review listening.  Please feel free to ask questions about the P2+1.

Thank-you for introducing us to yet another custom option and I appreciate your willingness to post part of a review in progress.  Your readers can get impatient (whistles innocently) so this approach isn't a bad one.

 

How does this compare to the similarly arrayed Alclair Reference?

I still have to do my official A/B comparison, but the presentations are very very different.

Given your description, would it be right to call these a cross between the Mi3 and T1 Live! ? Of course being cheaper is a big draw. How do they compare to the Earsonics house sound?

The Mi-3 puts you quite far back from the presentation...it projects very far while the P2+1 puts you on stage closer to the presentation of some of the EarSoncis products, such as the SM3 and EM3 Pro.  The T1 Live isn't as mid-forward and the EarSonics house sound is more liquid and richer, but I will have more specific answers once I do my A/Bs.  If you are making a decision between two, let me know and I can move an A/B session up in my schedule.

Not urgently making a decision between the two, but certainly considering it for some time within the next few weeks/month. Since I'm in the UK and on a budget, the Mi3 and P2+1 are the two that seem to be the most viable options right now.

 

I enjoy the Earsonics sound so I think the EM4, judging by your descriptions, would be perfect. Just it's a little too pricey.

 

Looking forward to further impressions.

Is it too late for me to ask about the cable they have provided?

I was looking around and i saw this cable listed on Sensorcom website.

Will it fit IEMs with westone pin sockets?
